Officials shut down a western Pennsylvania dairy for a second time this year because tests showed tainted milk.
State health and agriculture officials say consumers who purchased milk from the Brunton Dairy in Beaver County should immediately discard all milk with a sell-by date of Oct. 25 or later.
The Department of Agriculture says in a release that it found Yersinia bacteria during ongoing testing of the dairy, which also closed in July after concerns that the bacteria were sickening its customers.
Officials allowed the family-owned business to resume sales in early October.
