The aim of the study was determination of the contamination of raw milk, milk for consumption and powdered milk with antibiotics and inhibitory substances. The study was carried out in the years 1990-1993 with the assistance of the Province Sanitary-Epidemiological Stations using methods agreeing with the Polish Norms 91/A-86033: the enzymatic test Penzym, the microbiological tests S.STD Polulest and the plate method. In all, 16334 samples were tested.
Depending on the method used the number of positive samples was:
- in raw milk: from 13.1 to 22.4%
- in milk for consumption: from 10.5 to 19.5
- in powdered milk: from 12.9 to 18.2%.
These results point out that the health quality of milk is insufficient, both milk for processing and milk in the market failing to meet the standards. The source of the seem to be inadequate hygienic conditions during milking and, especially, failure to meet the necessary requirements for keeping the time period during which milk is not suitable for consumption after treatment with antibiotics.
