Anyone who thinks they may have purchased the crisps recently has been warned "do not eat" the product due to a life-threatening labelling error. The Food Standards Agency stated: "This product contains milk and soya, making it a possible health risk for anyone with an allergy or intolerance to milk or milk constituents and/or an allergy to soya."

Anaphylaxis UK provides important information for those affected by a milk or soya allergy.

There are two types of milk and soya allergies: immediate and delayed. With immediate reactions, symptoms can be mild or moderate, but in some cases, they can cause anaphylaxis.

Mild to moderate symptoms of both allergic reactions include a red raised rash (known as hives or urticaria) anywhere on the body; a tingling or itchy feeling in the mouth; swelling of lips, face or eyes; and stomach pain or vomiting.

Anaphylaxis is a more serious reaction involving difficulty breathing or affecting the heart rhythm or blood pressure. Symptoms include:

• Swelling in the throat, tongue, or upper airways (tightening of the throat, hoarse voice, difficulty swallowing)
• Sudden-onset wheezing, breathing difficulty, noisy breathing
• Dizziness and feeling faint
• Sudden sleepiness, tiredness, and confusion
• Pale, clammy skin
• Loss of consciousness
