Pennsylvania officials said their tests for bacteria in samples had not yet yielded results.

Later Thursday, the Berkeley County (W.Va.) Health Department reported that two Eastern Panhandle residents were stricken with the Campylobacter bacteria, according to a news release. The health department attributes the cases to the Family Cow farm outbreak, the release said.

The Family Cow farm sells raw milk at its farm store and at drop-offs, grocery stores and markets around Pittsburgh, Philadelphia, the Lehigh Valley and southcentral Pennsylvania. According to the Family Cow website, the farm has decided to temporarily stop selling milk.

Thirty states, including Pennsylvania, allow raw milk sales, according to the National Association of State Departments of Agriculture.

Sales are prohibited in Maryland.

In Pennsylvania, 153 facilities hold raw milk permits from the state agriculture department, agency spokeswoman Samantha Krepps said.

Five farms in Franklin County appear on a permits list on the Pennsylvania Department of Agriculture’s website.

“They have to pass an inspection by the department of agriculture,” Krepps said of farms seeking a permit.

The inspection involves the milking parlor, storage areas, temperatures and distribution practices, Krepps said. Farmers also are required to ensure there are consumer notices on containers and displays, she said.

After the initial inspection, permitted farms are required to submit to four inspections each year. They must file veterinary documents ensuring herd health with the agriculture department’s food safety division.

Phil Wagner grew up on a dairy farm and spent 36 years as a Penn State Cooperative Extension educator before retiring in 2010.

Wagner said he saw raw milk sales start to become trendy about five or six years ago when consumers started seeking “natural” foods.

“There have been people selling raw milk for years. ... It’s nothing new,” Wagner aid.

However, farmers who sold to neighbors 20 years ago got away from the practice because of permitting, he said.

“It’s a very niche market, and you only have a certain amount of consumers,” Wagner said.

Logan Horst, who was raised on a Chambersburg-area dairy farm, is a Penn State Cooperative Extension dairy educator in Franklin County.

Horst said selling raw milk gives farmers an opportunity to control their own marketing, rather than selling to a cooperative and having their pasteurized milk fall under regulated prices at the grocery store.

“People are willing to spend more for (raw milk) for whatever benefits they perceive it has,” he said.
