The Pensylvania Department of Agriculture has advised consumers who purchased raw milk from Jersey Hollow Farm near Kutztown to throw it out immediately because of potential bacterial contamination.
But the dairy owner, Norman Sauder, doesn't believe his milk is contaminated.
He said his own test from the same batch showed no bacteria.
A second test he arranged with a certified tester also came back negative, said Sauder, who milks 35 cows.
"They want to scare the public that raw milk is bad," he said of state inspectors.
Selling raw milk directly to the public cuts out milk-processing middlemen, who have close ties to department officials, he said.
Sauder said he is paid $1.20 a gallon for his milk and that he has to pay to truck it to the processing plant.
According to a news release, the department lab found salmonella in a milk sample taken from the dairy July 19. The bacteria's presence violates the Milk Sanitation Law.
The Sauders have agreed with the department's request to stop selling raw milk for human consumption.
Symptoms of salmonella include nausea, vomiting, diarrhea, fever, headache and abdominal cramps. The symptoms can appear anywhere between six hours and four days after infection.
The department is moving to suspend Jersey Hollow Farm's raw milk permit until additional milk samples are tested and found to be free of salmonella and other pathogens.
The farm also must pass a state inspection before raw milk sales can resume.
