[Microbiological and parasitological risk analysis of novel food sources obtained with the use of insects].

The problem of food safety being an important component of the country's food security, provides not only for continuous improvement of the methodology of hygienic standardization, but also for the formation of requirements for novel food, in particular, those obtained from non-traditional sources. The accumulated practical and theoretical competence in the food hygiene area, as well as knowledge of current trends of the food base broadening, allow us to analyze the risks associated with novel food obtained of insects. The purpose of the research was to analyze the microbiological and parasitological risk of novel food sources obtained with the use of insects, suggest the effective risk management measures. Material and methods. The analytical part of the work included literature search, collection of information and statistical materials published in domestic and foreign scientific editions. The search was carried out using the Google Academy retrieval system and electronic databases (PubMed, MEDLINE, EMBASE, Scopus, Web of Science, eLIBRARY), mainly in the last 25 years, using the keywords: Hermetia illucens, Tenebrio molitor, Acheta domesticus, insects, parasite, nematode, pathogen, cysts. Results. Based on the published materials' analysis, a systematization of microbiological and parasitological factors potentially capable of colonizing edible insects has been carried out. There were identified representatives of 24 groups of pathogenic and 18 opportunistic microorganisms and helminths related to microbial and parasitic pathogens, the spread of which is significantly influenced by inappropriate conditions of feeding and keeping insects. As there are currently no veterinary requirements for insect breeding and farming conditions, contamination of end products with infectious and parasitic pathogens can vary over a very wide range. Conclusion. The use of native insect biomass carries certain risks associated with its microbial and parasitic contamination, and the development of measures to prevent them requires significant resources. The possibility of deep processing of such raw materials can be considered as one of the solutions to mitigate these risks. For use in the food industry, insects should be subjected to processing similar to that currently used for soybean seeds, which includes separation of protein (entomoprotein), fat and chitin fractions, each of which would have an independent use. Thus, at present, insects should be considered as a source of novel food ingredients, first of all, complete protein of animal origin.

A parasitological evaluation of edible insects and their role in the transmission of parasitic diseases to humans and animals.

From 1 January 2018 came into force Regulation (EU) 2015/2238 of the European Parliament and of the Council of 25 November 2015, introducing the concept of "novel foods", including insects and their parts. One of the most commonly used species of insects are: mealworms (Tenebrio molitor), house crickets (Acheta domesticus), cockroaches (Blattodea) and migratory locusts (Locusta migrans). In this context, the unfathomable issue is the role of edible insects in transmitting parasitic diseases that can cause significant losses in their breeding and may pose a threat to humans and animals. The aim of this study was to identify and evaluate the developmental forms of parasites colonizing edible insects in household farms and pet stores in Central Europe and to determine the potential risk of parasitic infections for humans and animals. The experimental material comprised samples of live insects (imagines) from 300 household farms and pet stores, including 75 mealworm farms, 75 house cricket farms, 75 Madagascar hissing cockroach farms and 75 migrating locust farms. Parasites were detected in 244 (81.33%) out of 300 (100%) examined insect farms. In 206 (68.67%) of the cases, the identified parasites were pathogenic for insects only; in 106 (35.33%) cases, parasites were potentially parasitic for animals; and in 91 (30.33%) cases, parasites were potentially pathogenic for humans. Edible insects are an underestimated reservoir of human and animal parasites. Our research indicates the important role of these insects in the epidemiology of parasites pathogenic to vertebrates. Conducted parasitological examination suggests that edible insects may be the most important parasite vector for domestic insectivorous animals. According to our studies the future research should focus on the need for constant monitoring of studied insect farms for pathogens, thus increasing food and feed safety.
