Ensuring the population’s access to high-quality and safe food products is of exceptional
social and epidemiological importance. This is especially relevant for livestock products,
particularly meat, since under modern production conditions there are numerous factors
affecting its quality and safety. According to statistical data, about 15.0% of meat and meat
products entering the retail market are found, based on veterinary and sanitary inspections, to
have various defects. Food safety is determined by compliance with established requirements
for a range of indicators, including microbiological contamination, radionuclide content, and
xenobiotics. Determining these indicators involves specific methods that are often complex,
time-consuming, and, most importantly, do not allow for predicting the combined effect of
contaminants on the organism. In contrast, the express method developed by the authors for
determining overall toxicity through biotesting, using the ciliate Colpoda steinii as a test organism
(“Method for determining the toxicity of meat from slaughtered animals”, utility model patent of
Ukraine No. 149685, 48/2021), makes it possible to account for the effect of the tested sample
on the organism as a whole. In this study, we assessed the degree of freshness and overall toxicity
of meat sold in the retail network of Odesa. The research objects were beef samples (n = 25),
lamb samples (n = 15), and pork samples (n = 20). Freshness testing showed that, according to
organoleptic and biochemical indicators, 88.0% of beef samples, 86.67% of lamb samples, and
85.0% of pork samples were of good quality and fresh. The remaining tested samples were
classified as being of “questionable freshness”. The overall toxicity assessment showed that
100% of fresh pork and lamb samples did not exhibit any signs of toxicity, while one beef sample
demonstrated slight toxicity. All samples classified as “questionably fresh” showed varying
degrees of overall toxicity: slight toxicity was found in two beef samples, one lamb sample, and
one pork sample; moderate toxicity - in one lamb sample and two pork samples; and strong
toxicity - in one beef sample.The obtained results indicate that 16.0% of beef, 13.33% of lamb,
and 15.0% of pork entering the retail market exhibit overall toxicity and pose a potential hazard
to consumers.
