Weis Markets is announcing a recall of some of the store's milk products.

In a call placed to customers Friday night, Weis announced that Weis Quality Milk products of the whole, 2%, 1% and skim varieties, with a sell by date of December 5th, may contain antibiotic residue. That, the call said, may cause problems for people who are allergic to antibiotics.

The recall only affects milk with a sell by date of December 5th. It does not affect any other milk products Weis sells.

Customers with questions can call the Weis Markets customer service hotline at 866-999-9347. The recalled milk may be returned for a full refund.
