For the effective and safe implementation of quarantine measures for the prevention of infectious diseases, it is necessary to a create the conditions for the maintenance of physical and mental health of the population, especially of the children and adolescents, the most vulnerable part of it. The monitoring of quarantine conditions, as well as a lifestyle of children with the identification of possible negative factors affecting the health of schoolchildren, is a prerequisite of it. Objective: We assessed the living conditions of school-age children during the COVID-19 pandemic lockdown. Materials and methods: We analyzed the results of the online survey of the parents of 920 children and adolescents from all regions of Ukraine (497 boys and 432 girls). All respondents signed informed consent. Data were collected from April 17 to June 5, 2020. We applied STATISTICA 8.0 for statistical analysis. Results: Only (59.4±1.7)% of urban and (33.1±4.3)% of rural families with school-age children adhered to quarantine rules (p<0.001). The probability of the deviation from the quarantine rules is 1.7 times higher in rural regions than in urban ones (RR=1.65; CI 1.42-1.92; p<0.001), and 1.4 times higher in the parents with secondary education than in the parents with higher education (RR = 1.41; CI 1.22-1.62; p<0.001). (25.0±1.4)% of school-age children were determined not to leave their homes during the lockdown. About 60% of school-age children went for a walk 1-7 times a week (10-60 min/day). Proportion of children and adolescents with walk duration of more than 60 min/day with a frequency of 5-7 times a week during quarantine made up only (10.3±1.0)%, while before quarantine - 48.5%. Conclusions: Revealed trends demonstrate a need for the development and promotion of the measures for the rise of the population awareness on the importance of compliance with quarantine rules, taking into account demographic and social characteristics. It is necessary to develop ways to achieve optimal duration of outdoor walk for children.

The analysis of the documents of the authoritative international organizations and scientific works was carried out from the point of view of the development of the strategy for ensuring the radiation quality of drinking water. The radiation parameters of the quality of drinking water, the interpretation of monitoring results by screening and recommended levels, the value of the individual dose criterion, as well as algorithms for establishing the frequency of monitoring of the radiation parameters of drinking water were considered. Objective: We analyzed the documents of reputable international organizations and scientific works in terms of the development of the strategy for ensuring radiation quality of drinking water and the features of the practical application of the parameters of water radiation quality in the world and Ukraine. Methods: bibliographic, analytical. Materials: We performed the analysis of the documents of international organizations (WHO, IAEA, ICRP, UNSCEAR), as well as scientific publications on the radiation quality of drinking water in the light of the experience in measuring the content of drinking water radionuclides at the territory of Ukraine. Results: Materials of the international documents and scientific publications demonstrate that the assessment of radiation quality of drinking water requires a balanced analysis. In some cases, based on the results of only one determination of the total alpha and total beta activity, it is impossible to draw an unambiguous conclusion about the suitability or unsuitability of drinking water for consumption. Taking into account the geological heterogeneity of the territory of Ukraine, in order to obtain sufficient data on the radioactivity of groundwater, it is necessary to conduct extensive screening studies of the radiation quality of water in the regions of the country with the involvement of geological and monitoring services, local authorities.

Objective: We assessed the conditions of the work of medical personnel under conditions of the coronavirus COVID-19 pandemic and determined the risks associated with them. Materials and methods: We used bibliographic, hygienic, questionnaire and mathematical methods in the study. The results of our own observations, questionnaires for a survey of medical workers, data of the WHO, Ministry of Health of Ukraine, Center for Public Health of the Ministry of Health of Ukraine, the State Labour Service of Ukraine, data of the State Statistics Service of Ukraine and thematic scientific sources of information were used as a material for the study. Results: The work of medical workers, involved inthe COVID-19 pandemic overcoming, is classified as dangerous (extremal). The risk of infection of medical personnel with the SARS-CoV-2 virus is increased with a deficiency of personal protective equipment for medical workers and its wrong application. The work under dangerous conditions of work at the healthcare institutions leads to a high incidence of COVID-19 in medical workers. Nursing personnel (38.43%), junior nursing staff (22.69%), anaesthetists (5.87%) predominate among medical workers with acute occupational disease COVID-19. Conclusions: The analysis of the results of performed studies allowed to make a conclusion that measures for the prevention of the incidence of COVID-19 in medical workers and measures for the improvement of the safety of the hospital environment should be aimed at more stringent compliance with national legislation and regulatory-and-methodological requirements for the protection of the conditions of workin medical personnel and infection control at the healthcare institutions

Objective: We evaluated and analyzed the level of dietary supplement (DS) consumption in Ukraine and detected the risks arising with their consumption. Materials and methods: We conducted a questionnaire-based survey on the issue of DS consumption among the residents of the cities of Kyiv, Poltava, Kharkiv and Vyshneve (Kyiv oblast). We analyzed the statistical data on the number of the Ukrainian population, availability of the pharmaceutical facilities in the regions of Ukraine, DS sale volumes and laboratory data, concerning correspondence of DS to the claimed composition of active ingredients. Statistical analysis was carried out with the help of the standard software Microsoft Excel 2007 and STATISTICA 8.0. Results and discussion: The survey allowed us to evaluate the health state of the respondents taking DS, to find out the information concerning recommendations for the application of DS, to detect the ways of the purchase of the product, to identify the risk of poor-quality DS taking. According to the survey results, about 72% of the respondents are taking DS. The survey results indicate that 39% of the respondents, taking DS, are healthy, almost a half of the respondents have insignificant health problems and about 12% of the respondents have serious health problems.79% of the respondents buy DS at the pharmacies, it allow us to conclude that about 59.7 million packagings of DS were consumed in Ukraine in 2019. It has been proved that the provision of the population of Ukraine with pharmacy institutions is even for all regions of Ukraine and, accordingly, the population has the opportunity to purchase necessary DS at the pharmacies. Taking into account the results of the laboratory tests of DS quality, the risks of the consumption of poor-quality DS may be about 9.5% in Ukraine in 2019. The results of the investigations of the control procurement show that given risk may be increased significantly. Conclusions: The level of the consumption of dietary supplements by the Ukrainian population was established. It was found that the most widespread way of DS purchase is a network of pharmacies, but nearly 20% of all respondents, taking DS, purchase them at the web-stores, through network marketing, etc. The similar ways of the purchase cannot be easily tracked and are not under serious control, which creates significant risks of DS falsification, therefore, much attention should be paid to these indicated ways of distribution. It was established that in Ukraine, the probability of the consumption of non-compliant DS might be up to 9.5% (among those who used DS) in 2019. For the safe use of DS by the citizens of Ukraine, it is necessary to have a confirmation of the qualitative and quantitative composition of the active components of DS while conducting their quality and safety control.

Objective:We identified the social risks among the population of surveillance areas (SA) of the NPP and their impact on socio-psychological state. Methods: In the course of the work, we performed the comparison of the assessment of the life quality by the population in the SA of Rivne NPP (RNPP) and South-Ukrainian NPP (SUNPP) located in different physical-and-geographical regions of Ukraine. We studied seven spheres of life quality, the level of psychological stress, and the concern about the risk of the emergencies among the population. The samplingpopulation made up 232 people in the SA of RNPP and 227 ones in the SA of SUNPP, the sampling error was 5.4%. Results: Employment, democratic governance, health are the critical spheres of life for the population of satellite cities, and welfare, living conditions, employmentare the critical ones for the population ofrural areas. The assessment of the level of well-being is closely connected with the assessment of living conditions, job satisfaction is closely connected with the sphere of security, social protection and the well-being level. Reliable connections have been established between the socio-psychological state of the population and the main spheres of life quality among the population in SA of the NPP: high - among the indicators of the scales of somatization, concern and reactive anxiety and the sphere of security and protection, medium - with the spheres of employment and welfare, low - with the sphere of health care. Conclusions: The data of the sociological survey of the population of SA of the studied NPP indicate the community of interests and demands of the population. The population of SA of RNPP and of SUNPP is characterized by the territorial behavior, stipulated by the awareness of the subject of their attitude to the area, where the activity of the NPP is a leading factor. Most of obtained assessments of the spheres of quality of life are similar in values irrespective of theregion. The involvement of the population of Rivne region in the liquidation of the consequences of the Chernobyl accident affects the concern of the population in case of possible man-made emergency. The population of SA of the SUNPP has a higher level of concern about social emergencies, including possible hostility and terrorist attacks, in particular.

Оbjective: We improved the hygienic criteria to ensure optimal conditions, training, and preservation of the health of primary school age pupils, which are common for the assessment of architectural-and-planning decisions of urban and rural secondary schools in accord with modern town-planning and sanitary legislation. Materials and methods: We applied bibliosemantic, analytical methods, method of sanitary-and-epidemiological examination of construction projects, sociological, instrumental and medico-statistical ones using StatSoft STATISTICA (v.5.5) application packages, Excel. Results: The exceeding 1.8-2.3 times the number of the actual studies that do not meet the standards for natural light and noise in urban secondary schools in comparison with the rural secondary schools, is due to the dense town-planning situation. The results of the survey of the parents of the pupils in grades 1-4 on the impact of dense school conditions of secondary schools on the indirect parameters of architectural-and-planning decisions showed that in case of insufficient space of the school room, a poor well-being was registered in 26.3% of pupils (rS <0.78), impairment of working capacity was noted in 18.75% of schoolchildren (rS <0.88).The presence of numerous interrelations between direct parameters of architectural-and-planning decisions (the intraschool space is formed according to them) and the pathological affection of urban schools’ pupils was determined. Conclusions: The occupational diseases in primary school age pupils are caused by direct and indirect impact of the parameters of architectural-and-planning decisions and hygienic provision of optimal conditions at urban and rural educational institutions by the improvement of the design of new and reconstruction of existing schools according to the hygienic criteria. We have developed a set of preventive measures to prevent these diseases.

Objective: We analyzed the current state of the study of the problem of OCC in drinking water according to the results of research of the Ukrainian scientists. Materials and methods: We used the sources of the scientific literature on the field, experimental, toxicological and epidemiological studies of OCC in drinking water. We applied the method of theoretical analysis of the scientific information. Results: The contribution of the Ukrainian scientists into the study of the problem of organochlorine compounds in drinking water of Ukraine is shown.The spectrum and levels of volatile THM and non-volatile HAA in tap water have been established. The distictions and basic regularities of their formation at the use of different chloragents (gaseous chlorine , sodium hypochlorite, chloramine, chlorine dioxide) and removal of water pipelines at the treatment plants, influence on the process of formation of various natural and technological factors (type anddose of chloragent, concentration of organic substances, exposure, pH, temperature etc.) have been defined. The obtained findings of the research on the problem of OCC in water are new for Ukraine, they indicate a potential threat to the health of the population at the long-term consumption of drinking water contaminated with OCC in excess amount. In recent years, the first results of biomedical studies of the effects of the contaminated with OCC drinking water on the organism of the animals and human health have been obtained. Epidemiological data on the effects of long-term consumption of chlorinated drinking water with excess OCC on non-communicable morbidity are being accumulated.

Objective: We determined a list of the objective research methods for assessing the sanitary and epidemiological welfare of institutions for children in the context of reforming the medical and educational systems in Ukraine. Materials and methods: A range of issues and research methods in child institutions of various types, regarding their sanitary and epidemiological welfare was determined on the basis of the analysis of scientific literature, evaluation of laboratory research results on the functioning conditions of child institutions conducted by the regional laboratory centers of Ukraine, data of the State Statistics Committee of Ukraine, own research in 2018-2019. Results: Taking into account the processes of the reform of medical and educational systems in Ukraine, the issues of sanitary-chemical, sanitary-bacteriological, physical research and assessment of the risk from economic activities of child institutions: nutrition safety; anti-epidemic measures of the occurrence and spread of infectious diseases; the quality of air environment and child household items; lighting and microclimate in the main premises for children’s stay; the presence of noise and vibration factor, electromagnetic radiation (EMR); organization of training process; indicators of the health of children remain relevant. Conclusions: Nowadays, the identification of the risk factors for child health during their education should be underlined. The inconsistency of state control between different departments leads to a violation of the healthy conditions for vital activity of the large groups of children, a deterioration of the material and technical equipment of the laboratory base and a decrease in the professional competencies of the specialists of laboratory medicine.

Objective: We carried out the epidemiological analysis of the incidence of non-tumor diseases of digestive organs in the people evacuated from the 30-kilometer zone of the Chornobyl NPP at the age of 18 years and older during the post-accident observation period. Materials and methods: In the post-accident period during1992 - 2016, we performed an epidemiologic study of the incidence of non-tumor diseases of the digestive system in 7,143 people (2,198 men and 4,945 women) aged 18 years and older evacuated from the 30-kilometer zone of the Chornobyl NPP. To assess the digestive disease incidence in the examined people, we studied a structure of the diseases according to the international statistical classification of the diseases of the tenth revision (ICD-10) by the information base of the clinical and epidemiological register of the NACRM NAMSU. Results: As a result of the study of the structure of digestive system diseases, it was found that 91.05% belonged to somatic pathology by the Digestive Diseases’ class. The health of the examined by this class persons deteriorated mainly due to the the development of the diseases of oral cavity, salivary glands and jaws, which made up the largest component (47.17%) and the diseases of esophagus, stomach, and duodenum (34.39%). But a significant loss of health was caused bythe diseases of the gall bladder, biliary tract and pancreas, chronic hepatitis and cirrhosis(8.13%), non-infectious enteritis and colitis, and other diseases of the intestine (1.36%). Only digestive pathology made up8.9% among different classes of ICD-10: "Some infectious and parasitic diseases (A00-B99)", "Tumors (C00-D48)", "Congenital abnormalities (malformations), deformities and chromosomal abnormalities (Q00-Q99)". Irrespective of gender, the morbidity structure of males and females is characterized by the identity of the diseases and the ratio of indicators in the structure of the overall cohort. But females suffered more from gall bladder disease, biliary tract and pancreas disease, oral cavity disease, the malesfrom esophageal, stomach, and 12 duodenal diseases. Conclusions: Determination of the structure of the diseases on the example of diseases of the digestive organsamong the people aged of 18 years and older, evacuated from the 30-kilometer zone of the Chornobyl NPP, enables the identification of priority nosological forms for further illustration of the determined relationship of the effect of ionizing radiation on the health status of the suffered for preventive measures.

The ecologically dependent diseases are gaining more and more weight in the structure of the general morbidity of the population, and as a result, there is a need to develop the scientific bases of the ecological safety of Ukraine, a methodology for provision and its implementation. Objective:We developed a conception and a methodology for the functional and ecological expertise (FEE) of the regions of radiological (ecological) control in Ukraine and a fast simple method for the assessment of the functional and vegetative health of children. It will make it possible to identify the areas with a high integral ecological load for a human and provide functional and vegetative certification of the children’s population. Methods: The FEE of the radiation control regions of Ukraine is based on the survey results of the functional and vegetative health of 18,650 children that lived in 92 settlements of the Vinnytsia (moderately contaminated), the Lviv (relatively clean) and the Chernihiv (strongly contaminated) oblasts of Ukraine in1993-2010. For this purpose, we used functional and vegetative diagnosis of the vegetative health of the children’s population after the V. Makats’ method, which makes it possible to reveal the indices of the dispersion of the vegetative levels which are the integral bioindicators of internal homeostasis. The integral features of the ecological state are formed on this basis and the zones of its ecological pressure are determined as well. Results:The FEE results of the Lviv oblast (2001-2006) showed a compliance with the criteria of the official dosimetric certification of the RS and the stable preference of the sympathetic activity in the children was revealed. According to the FEE results inthe Vinnytsia oblast (IV radiation control zone), only one case (Chervona Hreblia village, Chechelnytsk area) of a discordance with the official dosimetric certification criteria of the RS (according to the FEE, it is in the "Functional safety" zone) was revealed. The FEE confirms the classification of the number of RS in the Chernihiv oblast as "relatively radiation-free" ones. At the same time, in 2000, according to the functional health of children, the Borzna area (Borzna, Velyka Zahorivka, Shapovalivka) was assigned to the zone of " the development of functional strain" and the Ichnia area (Ichnia) - to the zone of the "development of functional catastrophe" (IV zone), which does not meet the criteria of the official dosimetric certification of the RS. Conclusions: The results of the FEE of the functional health levels, obtained at the contaminated territories of Ukraine, coincide with the data of the state radiological monitoring which indicates the effectiveness and reliability of the proposed FEE method. The FEE, as a method of bioindication, based on the functional and vegetative health of children under modern conditions, is a highly sensitive method for the identification of the environmental problems of the territories and it fundamentally complements the accepted forms of dosimetric and thyroid dosimetric control.

Objective: We developed the hygienic approaches to the assessment of planning decisions of the cities with different city-forming systems in terms of environmental pollution and risk to the health of the population. Methods: We used a set of general scientific and special research methods: bibliosemantic (for the analysis of regulatory and legal literature in the sphere of town-planning), theoretical (evaluation of the retrospective data of the research on the hygiene of planning of the settlements), analytical (development of the method for hygienic evaluation for various purposes), sanitary-epidemiological examination of master plans of the cities and SPZ for the objects of different hazard class, epidemiological and medico-statistical ones. We applied a risk assessment methodology to evaluate the risk of exposure of chemical pollutants of ambient air of the cities to the population. Results: The cities were studied taking into account the nature of the main sectors of the economy which form their city-forming base, as well as the features of the planning structure of the cities, which made it possible to identify the residential areas that were heavily influenced by the industrial enterprises and beyond their influence. The obtained data make possible to develop measures for environmental adjustment and to resolve reasonably the issues of general plans for urban development of the cities, taking into account the specificity of the development of main industrial complexes, to make management decisions on the ground, their implementation to create safe conditions for human vital acitvity. The processes of restructurization of the major branches of heavy industry, the consolidation and re-profiling of large industrial complexes and enterprises, and the intensive development of relatively small production facilities have become essential. In connection with the scarcity of land resources in the largest cities and megalopolises, the issues of the siting of existing filling stations and the design of prospective residential buildings near them, as well as the siting of designed filling stations under conditions of existing residential development, amid the rapid motorization of modern society are becoming increasingly important and require legislative regulation of the standardization of the SPZ for modern filling stations, taking into account not only hygienic requirements, but also the requirements of fire safety.

Objective: We summarized the results of published research papers related to the development of the main areas of personalized medicine in health care practice, including occupational medicine and definied the prior issues that dictate the need for further study. Materials and methods: We performed the analysis of literary data on the use of personalized medicine for the prevention of the occupational diseases. Results: The personalized medicine was established to be a relatively new promising direction for the further development of medical science, its main task is to create an optimum model of the health care system in order to preserve the health of the working-age population. At the present stage of scientific and technological progress development, the crucial in the implementation of the basic principles of personalized medicine (prognostic, personalized, preventive and partner), as an integrative modeling system, is given to the development of information support and molecular genetic methods for the study of public health for the purpose of early detection, prevention and treatment of diseases. Conclusions: Despite the prospect of using the concept of personalized medicine in the health care system, the domestic information and organizational, regulatory and legal (medical in some cases) base is significantly behind the needs of modern times, which makes it difficult to implement this direction in practice. However, over many years of scientific research in domestic occupational medicine, a fundamental basis has been formed for the further development of the personalized approach to the prevention of health disorders amongworkers. Nowadays some progress is being observed in the field of the search for biomarkers for early diagnosis and prevention of the formation of chronic occupational and work-related pathology, the Register of the Occupational Diseases of Ukraine has been substantiated, the methodology for the assessment and management of occupational risks is being improved, in particular, quantitative assessment of the potential and real danger of work-related exposure which is the basis for the real prevention of occupational pathology as a part of individual approach to the patient. Taking into account the current realities, the solution of the problem of the health preservation in the working requires a comprehensive approach with the involvement of the specialists in various fields: hygienists, occupational therapists, medical geneticists, specialists in the field of information technology, health care organizers.

The aim of the work was to study the features of lipid peroxidation in the organism of the animals under effectof electromagnetic radiation. Material and methods.The investigations were carried out under conditions of 4-month chronic experiment on outbred white rats which were divided into groups according to the effective intensity of 2000 V / m •hv, 4000 V / m •hv and 6000 V / m•hv. Results.An increase ofthe LPO processes in the blood and liver has been established.These changes were manifested depending on the level of electromagnetic radiation intensity and exposure time. Non-enzymatic stimulation of Fe2 + -dependent lipid peroxidation, increase of the enzymatic NADPH-induced accumulation of TBA-active products in rat liver homogenate, increase in the dynamics of spontaneous MDA accumulation in rat blood plasma and liver homogenate were revealed. Conclusions.Performed investigations show that the enhancement of lipid peroxidation processes is a mechanism of the manifestation of the hazardous effect of EMR, which makes it possible to develop oxidative stress and, as an indicator of intracellular disorders, can serve as a biomarker of adverse effects. The severity of activation of lipid peroxidation system allows us to consider this as a criterion for the assessment of the hazard of the electromagnetic factor.

Objective: Our aim was to substantiate the methodological aspects of the study of the radon hazard of the territories. Materials and methods: The measurements of the radon-222 levels were carried out with the help of the passive track radonometry method in the heating season. Cellulose nitrate film of LR-115 type was used as a detector. The time of the exposure of radon accumulators made up 1-2 months. After the chemical etching procedure, the detectors were counted for the number of damage tracks by the method of spark counting. To establish the registration efficiency of the track detectors (calibration), they were exposed in the radon atmosphere with a known radon activity. The radon atmosphere, patented by the Institute of Public Health, is a calibration source accredited by the National Body of Standardization and Accreditation of Ukraine. Results: Indoor radon-222 measurements were performed in more than 30 thousand buildings. The indoor radon-222 EEVA geometric mean for rural houses was found to be 52 Bq*m-3 (for gas radon, this value is 130 Bq*m-3), for apartments located on the ground floor of multi-storied buildings - 40 (100) Bq*m-3, above the ground floor - 23 (58) Bq*m-3 with a standard deviation of 62 (155) Bq*m-3, 48 (120) Bq*m-3 and 28 (70) Bq*m-3, correspondently. The national average level of the standard for radon-222 of 100 (250) Bq•m-3 was found to be exceeded in 19% of cases, the level of 200 (500) Bq*m-3 - in 5.7% of cases. Effective radiation doses for the population of the country have been determined. Non-radiation factors, affecting the effectiveness of studies, have been analyzed. The algorithm for the assessment of the radon risk degree for the territory has been developed. It includes the analysis of the structure of housing resources, determination of the most typical engineering-and-planning solutions for buildings, integral method of radon measurement, identification of the critical types of buildings based on the measurements of radon levels, calculation of radiation risks from radon for the population. The basic requirements for the primary radon monitoring in the context of the action plan implementation have been identified.

Objective: to determine the dependence of the indicators of students’ health on the sanitary-hygienic conditions and the organization of training in urban and rural SEI. Methods: sanitary and hygienic examination; epidemiological method with the application of sanitary-statistical, mathematical and sociological analysis. Results: Our studies demonstrate that the material and technical basis of urban and rural SEI has not changed significantly over the last 20 years and does not meet the hygienic requirements (equipping with services and utilities - water supply, heating, sewerage; in architectural-and-planning decisions - set of premises, lighting, ventilation) in 72% of cases. It is especially concerned with the rural SEI, where there are no gymnasiums in 36%; assembly halls in 67%; training computer rooms in 69%. Due to the organization of the grades for the children six years of age on the basis of existing school premises, the index of actual occupancy of the SEI exceeds the design level by 26.7% in urban SEI and by 4.5% in rural SEI, which has resulted in a two-session training regime. Nowadays, only one-fifth of the first-grade students in Ukraine, i.e. about 22%, have necessary conditions for stay and study, and the rest, almost 78% of the first-year students study at SEI where there are no such conditions. In mentioned SEI, the data of statistical reporting and medical records of 49,193 students, have been studied and analyzed in details. The number of the children with functional disorders in health state (II and III health groups) is naturally higher in all age groups of surveyed students who studied at SEI with unsatisfactory sanitary-hygienic conditions and the organization of educational process in comparison with the similar indicators in their peers who studied under optimum conditions. Dependence of health indicators of the children on the conditions and organization of training at school has been substantiated. The proportion of sick students in 2nd, 5th and 7th grades with satisfactory conditions was lower in comparison with the similar grades where these conditions were unsatisfactory (13.3% vs. 15.8% (p <0.05) in 2nd grades; 9.5% vs. 10.2% (5

Background: A clearly structured hierarchical vocabulary related to logical and qualitative relationships in the field of food consumption, in other words, with their ontology, is extremely necessary to solve the problems of data harmonization which cover areas of food safety, certified quality, production technology, distribution, as well as health and comfort of the end-users of food. Objective: We analyzed the current state of the process of the development of standardized and computerized foodclassification systems that are connected to existing modern databases and provide real-timeinformation on the composition and nutritional features of foods. Methods: We used the methods of theoretical synthesis and deductive analysis, literary review of foreign scientific reviewed sources. Results: The lack of a single and understandable digital language was found to be an obvious gap in the field of computerization and unification of information on food products, as food objects are constantly moving from their natural or farm origin, through the technological processing and distribution chains to the consumers on different continents that are characterized by various nutritional and physiological needs that may differ in the countries throughout the world.
