Lehigh Valley Dairy is voluntarily recalling orange juice because it may contain milk, a common allergen.
The Food and Drug Administration said the recall Thursday affects multiple brands distributed to both retail and food-service locations in Pennsylvania, New Jersey, Delaware, Maryland, Virginia, West Virginia and Washington, D.C.
The affected brands and sizes are Lehigh Valley half pints, half gallons and gallons; Swiss Premium half gallons and gallons, and Price Chopper gallons.
The Allentown-based dairy said due to a manufacturing error, milk became mixed with the orange juice.
All of the affected products have a sell-by date of March 23 and plant code 42-099.
Lehigh Valley Dairy said consumers should discard the product and return the packaging to the place of purchase for a refund or exchange.
