New Jersey's agriculture secretary has issued a warning after raw milk from a farm in Pennsylvania was quarantined for potential health concerns.

Secretary Doug Fisher did not provide any details about the nature of the concerns, but says that the importation of raw milk for direct consumption across state lines into New Jersey is a violation of federal law.

“The New Jersey Department of Agriculture is working with surrounding states to determine the extent to which raw milk from the farm in question has been received by New Jersey residents and consumers at the New Jersey locations listed on the farm’s website,” Secretary Fisher said in a statement.

The milk came from Miller's Biodiversity Farm in Quarryville, Pennsylvania.
