A Wisconsin dairy is recalling cottage cheese after the state tested and found alkaline phosphatase, an enzyme naturally present in raw milk that is used as a measure of pasteurization in that it should be eliminated if processed properly. Since the enzyme was found to be present, this would mean that the milk used to make the cottage cheese was not properly pasteurized, and because of that, foodborne pathogens such as Salmonella could be present. It seems the dairy tested the cottage cheese and found no pathogens.
In reading the notice posted on the FDA website, it is hard to determine what the issue is. Going back to the Warning Notice published by WI Dept. of Ag, the issue is better detailed.
