Breese Hollow Dairy in Hoosick Falls has suspended raw milk sales after a sample tested positive for listeria yesterday.

The dairy says that a sample was taken Dec. 14 by the state Department of Agriculture and Markets and tested positive for listeria by the department’s food lab.

Listeria can cause listeriosis, a disease that can cause flu-like symptoms and more serious conditions in sick people.

No illnesses have been reported by the department from raw milk from the farm.

The dairy will not resume sales of raw milk until Ag and Markets re-samples the milk and determines that it is free of pathogens.
