Bacteria in Fresh Milk - what count of bacteria is found in the fresh milk?
What was the lowest allowed count possible of bacteria to have in milk when first secreted by the law of the USA in 1929?
Norms of today maybe slightly changed, but not too much. The answer was found in the magazine of the USA- The Creamery and MILK PLANT MONTHLY, Year 1929, Month of December.
The bacteria in the first secretion of milk - right after milking is always present, but theoretically in ultra sterile milking conditions, probably it is possible to have cows that give milk that is almost free of bacteria in the milk. However, the milking process will never be super duper sterile- this will never happen, so to expect the milk without any colony of bacteria right after milking the cow is the most unusual thinking.
It is generally accepted that the normal udder may and usually does harbor the standard bacteria throughout the whole extent of the lactiferous ducts of the normal cow, including the most minute ducts where the milk becomes contaminated as soon as secreted. The question is- what kind of bacteria are found in the milk is more important.
