Watkins Inc. of Winona, MN, is recalling 1,535 units of its individual 7.7 ounce containers of SoyNilla protein powder, because of an undeclared milk ingredient. SoyNilla was distributed nationwide through the Watkins network of independent contractors, associates and mail orders.

The recall was initiated after a routine review revealed that the product contained milk but that ingredient was not listed on the label, indicating a temporary breakdown of the company’s allergen identification process.

No illnesses have been reported.

People who have an allergy or severe sensitivity to milk may run the risk of serious or life-threatening allergic reactions in consuming it. Symptoms may include hives, wheezing, vomiting, anaphylaxis and digestive problems, such as bloating, gas or diarrhea.

The vanilla-flavored protein powder comes in a 7.7 ounce, white plastic package marked with lot #3000280 on the side of the package.

Consumers who purchased the 7.7 ounce of SoyNilla may call for a return or credit instructions. Consumers with questions may contact the company at 1-800-243-9423 from 7 a.m. to 6 p.m., CT, Monday through Friday.
