WASHINGTON — The US Department of Agriculture’s Food Safety and Inspection Service issued a public health alert on Oct. 6 for ready-to-eat stuffed pepper soup with meatballs due to misbranding and an undeclared allergen. The product contains egg, a known allergen, which was not listed on the product label.

The following soup product, which was produced on Sept. 28, is subject to the health alert:

• 32-oz. clear cups of “R KITCHEN Stuffed Pepper Soup with Meatballs” with a Best By: 11/27/23 date and lot code 048480 printed on the lid.

The product bears the establishment number “EST. 18019” inside the USDA mark of inspection and was shipped to retail locations in Massachusetts.

The manufacturer discovered the problem during a label review. A recall was not issued because the product is no longer for sale.

No confirmed cases of adverse reactions due to consumption have been reported.
