It is well-known that melliferous bees are the most sensitive indicators of ecologic conditions of natural environment. Researches in recent years show that bees and bee products can accumulate selectively some heavy metals, radioactive substances, pesticides and other polluters. Scales of heavy metals accumulation on the territory of Ukraine, as toxins of technologic origin unfortunately increase. Environmental pollution by heavy metals leads to their accumulation in plant and animal raw materials and production, consequently their quality decreases. It was proved that apiary accommodation in heavy metal polluted territories leads to their accumulation in pollen, honey bee-comb and wax. But the questions concerning study of peculiarities of sources, ways of pollution and heavy metals content in bee products are not enough lightened, and that was the purpose of our work. Generalized we present in literature information and results of our researches about the use of bees and bee products in quality of bioindicator contamination of environment by heavy metals. Dependence of content of heavy metals is set in the organism of bees in relation intensity of greening to contamination of environment. It is marked on the necessity of lead through of systems research in relation to determination of content of heavy metals in fabrics of bees and bee products with the purpose of search of new methodological approaches for authentication these toxicant of objective environment of contamination and him apimonitoring. Methodological elements of the researches of regularities of heavy metals and lipids content in the tissues of different anatomic sections of the organism and bee products were elaborated.

Over the past few years, the demand for the introduction of fish products in public canteens (schools, hospitals and nursing-homes) has grown due to their good nutritional proprieties. The particular health conditions and sensitivity of some groups of consumers exposes them to greater risks of food poisoning. It is therefore important to monitor the raw materials that end up in mass catering implementing strategies of mass catering control, both with self-monitoring strategies and with regular controls performed by the competent health authorities. The purpose of this study is to assess the overall quality of seafood dealt out from public catering services located in Northeast Italy. In this paper we illustrate the results of microbiological analysis performed on 135 fish samples (58% of samples were raw fishes, 27% cooked fishes, 6% raw fish products, 9% cooked fish products) and species identification performed on 102 fish samples. Additionally, 135 environmental swabs were collected to determine the effectiveness of cleaning and sanitation of food contact (cutting boards, cooking equipment and food processing surfaces) and non-contact (refrigerator wall and handle, tap lever) surfaces. Of raw seafood samples 24% had total aerobic mesophilic bacteria count &gt;10<sup>5</sup> CFU/g and for <em>Enterobacteriaceae</em> the faecal contamination was excluded since no <em>Salmonella</em> spp. and <em>Escherichia coli</em> were isolated. Just 3.8% of raw seafood samples resulted positive for <em>Listeria monocytogenes</em>. The results of swab samples of cooking utensils and surfaces showed that sanitation practices should be improved. Molecular analysis for fish species identification revealed a mislabelling for 25% of sampled fishes. The results of this survey can provide valuable information for monitoring and surveillance programmes for the control of quality of fish and fish products.

Fish is a valuable food product that has a high biological value, but spoils quickly because its muscle tissue contains a lot of moisture and can be contaminated with microflora through the intestines, mucus of the skin and gills. Insufficiently fresh fish can cause serious diseases: toxicoinfections and toxicosis, intestinal infectious diseases caused by Shigella, Salmonella, Escherichia coli, Proteus, Clostridia, various coccal microflora. The urgency of this problem encourages the study of sanitary-indicative microorganisms of fish and seafood to prevent foodborne infections. The purpose of the work was to study the microbial contamination of ready-to-eat fish and seafood sold in the retail chains of the city of Dnipro, to determine the compliance of product quality with sanitary requirements. Material and methods. 53 samples of fish and seafood of different brands were analyzed: 23 samples of low-salt products, among which were preserves from fish "Herring", preserves from mussels, salted low-salt and 30 dried products: dried squid, dried squid rings and dried bull. The number of mesophilic aerobic and facultative anaerobic microorganisms, Escherichia coli bacteria, the presence of coccal microflora, mold and anaerobes were determined in each of the samples. Results and discussion. The results of the sanitary-microbiological study showed that 43.4% of the analyzed samples (23 samples) did not meet the normative indicators. The largest deviations from the norm were found in the content of mesophilic aerobic and facultative anaerobic microorganisms and Escherichia coli bacteria. The study showed that in 39.6% of samples the number of mesophilic aerobic and facultative anaerobic microorganisms was exceeded, and in 32.0% - the number of Escherichia coli bacteria. Most contaminated products were found among the samples of dried squid – 50% of samples, preserves from fish "Herring" – 36.4% and preserves from mussels – 36.4%, dried squid rings – 33.3%. It was found that 18.8% of samples of fish and fish products contained Staphylococcus aureus, 7.5% of samples – sulfate-reducing clostridia. Conclusion. The obtained results indicated the non-compliance of a large number of fish and seafood with the normative indicators. This may be due to the condition of the reservoirs in which the catch was made, improper processing of raw materials, non-compliance with storage conditions, transportation of the product. Therefore, it is important to further improve the quality of fish products by controlling raw materials, compliance of production technology with international and national standards. The solution of this problem is possible under the condition of state involvement in the process of quality control of fish products on the market of Ukraine. The results of research can be used to monitor the quality of fish and seafood sold in retail chains

A key component of the quality management system is the incoming quality control of raw materials, materials and components. The course of the further production process and the quality of manufactured products depend on the correctness of its implementation, the accuracy of compliance with all the necessary procedures. Another important aspect that is inextricably linked with incoming inspection is working with suppliers. In order to minimize costs and increase the effectiveness of actions, it is necessary to establish a stable and well-coordinated work on the supply of raw materials, materials and components. To accomplish this task, the enterprise must develop and approve a methodology for evaluating suppliers, which allows them to conduct a comprehensive analysis, choose the most reliable suppliers with a proven reputation and high performance. The research base is a machine-building enterprise – public joint-stock company “NEFAZ” (PJSC “NEFAZ”). The article identifies problem areas and suggests methods for their improvement. Based on the results of the study, a comprehensive methodology for assessing suppliers has been developed, which makes it possible to determine the rating of the supplier and, depending on this, to establish the type of incoming control. Possible types of effect from the introduction of this technique at the enterprise are considered.

Marine fish species infested with Anisakidae larvae are reported in many fishing grounds. Besides the problems related to consumer’s health when the live larvae are ingested (anisakidosis) or to allergic problems caused by the larvae, the products excreted/secreted or released by the larvae are recognized as proteases, protease inhibitors or antioxidants, which can cause changes in fish muscle during storage. To study this problem, live larvae or a homogenate of larvae in water were added in controlled conditions to gelatin agar gels and minced fish muscle and stored at 20 or 5 °C for 7 days. A high activity in the gelatin agar gels was observed, whereas the inclusion of larvae or larvae homogenates in the muscle did not produce detrimental changes in texture, viscosity, color, or oxidation of fish muscle. The electrophoretic pattern of the extracted natural actomyosin presented fewer changes during storage in the larvae and larvae homogenate added lots than in the control lots. Nevertheless in naturally infested fish different parasite-host mechanisms might be involved. Parasitized fish has to be processed with treatments which kill the larvae to avoid consumers’ anisakidosis. However, as some of the Anisakis allergens are very stable to heat, patients allergic to Anisakis sp. have to be informed before ingesting parasitized fish or fish products.
