Mid-Atlantic retailer Weis Markets Inc. has recalled deli-made bacon, lettuce and tomato sandwiches due to undeclared allergens.

Sunbury, Pennsylvania-based Weis recalled its store-made BLT's because the mayonnaise used in them contains eggs. Eggs are not listed on the products’ packaging. The sandwiches, packaged in clear plastic containers, were sold in the delis of the 204 Weis stores in Pennsylvania, Maryland, Virginia, New Jersey, New York, Delaware and West Virginia.

One Weis customer had an egg allergy reaction after eating one of the sandwiches. The customer received an EpiPen injection and did not require hospitalization.
