Reason for Recall:

This recall was initiated when we determined that certain batches of Lay’s™ Classic potato chips contained milk which was not declared on the product packaging. The undeclared food allergen can lead to severe allergic reactions for individuals who are allergic to milk. Consumers commonly think of traditional potato chips as being milk-free, so this recall may be in other areas of concern. [3]

Health hazards:

Undeclared milk in food products may present a serious health risk to some individuals with milk allergies. Symptoms of a reaction to an allergic reaction may present as:

  • Skin reactions (hives, itching, or swelling).
  • Gastrointestinal issues (nausea, vomiting, diarrhoea, abdominal cramps).
  • Respiratory issues (wheezing, coughing, or shortness of breath).
  • Anaphylaxis (often life threatening which Immediate Medical Attention is required) – for example, an individuals’ throat may swell, they may feel dizzy and have trouble breathing.[4]

FDA recall instructions:

If you are a consumer:

  • If you are allergic to milk protein and have purchased the Lay’s Classic Potato Chips, DO NOT EAT this product.
  • Return the product to the place of purchase for a full refund.
  • If you consumed the product and develop symptoms, seek medical attention immediately.

Regulatory Responsibilities:

The FDA has a regulatory responsibility in the area of food safety when it comes to enforcing rules which obligate food manufacturers to accurately label allergens in the food they manufacture. This actual recall demonstrates how enforcement of food labelling laws is key to public health.

Manufacturer cooperation:

Frito-Lay will support the recall and has responsibility for removing all contaminated product off the shelf. The company will also be reviewing their processes for labeling to avoid similar issues in the future.

The FDA’s food safety responsibility:

The FDA is tasked with stakeholder safety within the U.S. food supply – the act of making sure that food products purchased by the public are safe to consume, wholesome and labelled for allergens. The FDA monitors and oversees the safety of the food supply by inspecting for compliance with the regulations.
