MILWAUKEE (AP) -- With buying from small, local, family-run farms becoming more popular, the results of a new study from Wisconsin could be surprising: It found that milk from big dairies is cleaner than that from small ones.
The lead researcher was Steve Ingham, a former University of Wisconsin-Madison professor who now works for the state agriculture department. He says he looked at cell and bacteria levels use to evaluate a cow's health and a farm's cleanliness and found them lower in milk from big farms.
All the farms met federal safety standards.
Wisconsin Farmers Union spokesman Tom Quinn dismissed the results, saying a truly meaningful study of milk quality would have to evaluate factors like taste and nutrition.
The study was published last month in the Journal of Dairy Science.
