The article presents the results of a comparative assessment and selection of effective methods for assessing microbiological contamination and the activity of disinfectants in the food production. At assessing the degree of microbiological decontamination in food production, the use of «Dip-slide», a polymer plate coated with the «Oxoid» medium, saves material costs and research time, as well as excludes subjective factors. The general regularities of the stages of formation of heterogeneous biofilms of microorganisms in the study of food raw materials, products, technological equipment and environmental objects have been revealed. At the first stage, the adhesion of vegetative forms of bacteria occurs, which have a shape and size typical of the species. Due to the coaggregation of cells, a monolayer of microorganisms was formed in the form of a diffuse layer. There were also identified secondary microcolonies associated with primary ones and separated by matrix voids, in the microcavities, the formation of cell strands in the form of beams was revealed. Dispersion of microcolonies was accompanied by the destruction of the extracellular matrix and the separation of cells capable of attaching to the surface and forming new microcolonies. Under the influence of various concentrations of chemotherapeutic and disinfecting drugs, the frequency of occurrence of clusters – the aggregation of microorganisms united by a layer of the extracellular matrix – significantly decreased.

The results of the technological assessment of new apple, cherry, black currant, red currant and gooseberry cultivars of VNIISPK breeding for the suitability for the natural food production are given. As a result, the cultivars that are promising for cultivation in raw plantings have been selected. For the production of raw materials in the juice industry, apple cultivars with a high juice yield and content of soluble solids higher than 10.0% were selected: ‘Bolotovskoye’ (Vf), ‘Candil Orlovsky’ (Vf), ‘Osipovskoye’ (3x), ‘Rozhdestvenskoye’ ((Vf + 3x), ‘Zaryanka’ (Vm), ‘Priokskoye’ ((Vf + Co), etc. Based on the long-term study of cultivars for their suitability for compote, jam and jelly, the cultivars that are most suitable for these types of processing are identified. It has been found that taking into account the daily needs of vitamins C and P as the most important antioxidants, all processed products from black currant can serve as their sources, all processed products from cherries, as well as apple juice and gooseberry marmalade can serve as a source of P-active compounds. All columnar apple cultivars as well as ‘Bolotovskoye’, ‘Rozhdestvenskoye’, ‘Veteran’, ‘Imrus’, etc. show high suitability for the production of apple chips. Cherry cultivars ‘Rovesnitsa’, ‘Putinka’, ‘Podarok Uchitelyam’ and ‘Novella’ are suitable for dried fruit. Based on the long-term studies of the technological qualities of the VNIISPK gene pool, a new generation assortment has been formed that has an optimal combination of chemical and technological indicators of fruits that meet modern technological requirements and are suitable for cultivation in the raw plantations of Central Russia.

The light industry is an important inter-sectoral segment and a chain of individual production areas. The purpose of the article is to carry out a comparative assessment of the cross-sectoral linkages of light industry of Ukraine with some EU countries and to prepare relevant analytical conclusions. The research revealed that the largest consumers of light industry products in 2013-2017 in Ukraine were the industries that belonged to this type of industrial activity (textile, clothing, leather and other materials), as well as the trade, furniture industry, public administration, and defense. The key problem for the functioning of the Ukrainian light industry is its high import dependence. In particular, the share of imports in intermediate consumption of light industry of Ukraine in 2017 was almost 60%. The share of imports in the expenditures of the Ukrainian light industry was almost 49%. The production activities of light industry in Ukraine use products of many ECs, but the main suppliers of raw materials and components are: textile production, production of clothing, leather, and other materials; production of chemicals and chemical products; wholesale and retail trade; supply of electricity, gas, steam, and air conditioning. In 2017, these four sectors totaled 70.74%. The following types of industrial activity in Ukraine have a significant potential for increasing output: production of rubber and plastic products; production of motor vehicles, trailers and semi-trailers; production of other vehicles; public administration and defense; compulsory social security; health care and social assistance. The further development and improvement of the technological level of Ukrainian light industry products requires greater integration of the latter with the trade sector. However, the trade sector in Ukraine requires a thorough “unshadowing”, i.e. legalization of all operations.

AbstractMicrobiological control is of crucial importance in the pharmaceutical industry regarding the possible bacterial contamination of the environment, water, raw materials and finished products. Molecular identification of bacterial contaminants based on DNA sequencing of the hypervariable 16SrRNA gene has been introduced recently. The aim of this study is to investigate the suitability of gene sequencing using our selection of PCR primers and conditions for rapid and accurate bacterial identification in pharmaceutical industry quality control.DNA was extracted from overnight incubated colonies from 10 bacterial ATCC strains, which are common contaminants in the pharmaceutical industry. A region of bacterial 16SrRNA gene was analyzed by bidirectional DNA sequencing. Bacterial identification based on partial sequencing of the 16SrRNA gene is the appropriate method that could be used in the pharmaceutical industry after adequate validations. We have successfully identified all tested bacteria with more than 99 % similarity to the already published sequences.

The quality of raw materials and goods of animal origin depends first of all on the safety of feed, their balance in terms of the main nutrients and digestibility by the body. As a rule, the lower the quality and safety of feed, the lower the productivity of all types of animals and poultry. The quality of feed is influenced by all stages of their production: growing conditions, harvesting and storage, processing technologies, canning and preparation for feeding. Where high-quality feed is used in diets, maximum productivity and high realization of the genetic potential of animals are obtained. During the storage and processing of plant and animal raw materials its physic and mechanical, biochemical, sanitary and microbiological properties change. This can be avoided only by observing the sanitary and hygienic requirements for bagging, harvesting, and storing feed. The quality of feed is confirmed by its physical, chemical, organoleptic, microbiological and other indicators, which determines the variety of feed control methods at all stages of their turnover. In this connection, the development and strengthening of control over the quality and safety of feed and feed additives is one of the important tasks of modern animal feeding science. The purpose of the work was to carried out a comparative assessment of four samples of the starting compound feed SK-3 for piglets of different producers. The experimental part of the work has been carried out in the laboratory of veterinary expertise at the compound feed plant LLC “Athens-Volga”. For the study of compound feed an average sample was taken from each sample, separating from the combined sample using a hand scoop according to Federal standard 13496.0-2016. Methods of sampling. Quality and safety control was carried out according to organoleptic, physic and chemical, microbiological indicators and the content of mycotoxins in compound feed. Monitoring of compound feed of the compared samples of the starting compound feed for piglets SK-3 according to the studied indicators has shown that all samples meet the sanitary and hygienic requirements of Federal standard of our country.

This study presents the results of the examination of potential donors of blood and its components for immunoglobulins M and G to patients with coronavirus disease 2019 (COVID-19) living in St. Petersburg. A total of 6782 people aged 1824 years were evaluated, which accounted for 2.07% of the regions population (326 760 people) of this age group. The study was carried out in the spring and autumn of 2020. A negative result (absence of antibodies) was obtained in 93.5% of the participants. The rates of immunoglobulins M and M + G were 0.58% and 4.18%, respectively, in the spring and autumn. Moreover, the number of participants who had immunoglobulins M and G + M in the autumn period was four times higher than the indicators of the spring period, which indicated greater infection activities in the population during this period. This is most likely due to the active movement of the population in the summer. When comparing the rates of COVID-19 infection and the frequency of occurrence in donors of the same age, markers of human immunodeficiency virus 1 and 2 and hepatitis B and C in 2020 (0.024, 0.012 and 0.13%, respectively) indicate the urgency of the problem of donor selection during blood services, especially during a difficult epidemiological situation because of COVID-19. Along with organizational measures for the selection of donors (e.g., attracting individuals from organized groups in which there are no signs of an unfavorable epidemiological situation to donation), mandatory testing of potential donors for immunoglobulins M and G should be considered.
