[Presence of chlortetracycline residues in the organs and tissues of poultry].

Poultry products (meat, liver, kidneys of hens and chicken) were found to be contaminated with chlortetracycline used as a stimulant of the poultry growth. From among 603 samples examined 91 (15.1 per cent) were found to contain residual amounts of the antibiotic comprising from 0.01 to 1.0 gamma/g of the tissue. Most often the antibiotic was definable in the tissues of the kidneys (24.7 per cent), liver (19.5 per cent) and more seldom in that of the muscles (2.4 per cent). Regular control is needed in the country over the presence of antibiotics in the products of poultry industry.
