DETECTION OF ANTIMICROBIALS IN RAW MILK CONTAINERS

Abstract

749 raw milk samples were collected from milk cans at the reception platform of dairy industries, distributed over Goiânia and in the interior of the State of Goiás, from April, 1984 to July, 1985. It was found out a prevalence of 7.47% of antimicrobian residues in this food. This value indicates the lack of worry by the Federal Inspection, A. M. , dairy industries, etc., with the quality of this product and with the public health. The comparative results related to the types of federal inspection existing at the dairy industries, approximate distance, in kilometers from farm to the reception platform, milk cans arrival time, dry and rainy periods, showed that the higher frequency of positive samples appeared in the dairies industries with permanent federal inspection, in the farms located 50 km from the dairy industries, and in the milk cans which arrived late to the reception platform. On the other hand, it was found the voluntary addition of antimicrobians in the milk by the conveyor to avoid its acidification. This result may explain a higher positive frequency of cases observed during dry period, instead of rainy period, as expected.
