[The occurrence of foreign substances in food products from animals fed food supplements of animal excrement].

The products of the animal origin (meat, organs, adipose tissue, eggs) from bulls, pigs and poultry which had been given animal excrements as supplements to their feeds (mostly pig excrements, in one case poultry excreta) were studied as to the content of foreign substances. The almost complete absence of aflatoxin and antimicrobial substances, and the determined levels of pesticide residues and chemical elements demonstrated that the studied foreign substances did not accumulate in the tested food as a result of the presence of non-traditional components in the diets of the animals.
