A Butler County diary farm’s raw milk has been contaminated with bacteria and customers who have bought any of the raw product should discard it immediately, the Pennsylvania Agriculture secretary warned yesterday. Raw milk bought from Fisher’s Dairy in Butler County has been infected with Listeria monocytogenes, the state’s Department of Agriculture reported. People who bought raw milk from the dairy after April 9 should dispose of it.
Listeria was found in a April 9 sample of raw milk from the farm. The bacteria can cause fever, muscle aches and sometimes gastrointestinal symptoms such as nausea or diarrhea. Raw milk is milk that has not been pasteurized or homogenized
The Department of Agriculture suspended sales of raw milk at the dairy. Multiple samples from the farm have to come back negative before raw milk can be purchased from Fisher’s.
