摘要：Seasonal contamination of milk with Butyric Bacteria was examinated in bulk milk over three years, 1987-1989. It was found that milk produced in summer season (April-September) was considerably less contaminated than milk of winter season (October-March). Spore counts in summer milk were varying from 0 to 200, mean 67 per liter, and in winter milk from 700 to 70.000, mean 12.665 spores per liter. Spores have not been detected in 48% analyzed samples of summer milk. Only about 34% samples of winter milk had less than 2.000 spores per liter. About 66% of samples contained higher number of spores and were unsuitable for cheesemaking.
