Book 9, Question 116
Why Does a Package Say ‘May Contain Traces of Nuts’?
A package says may contain traces of nuts to warn people with serious allergies! Factories sometimes make nut foods and other foods on the same equipment, so tiny traces can sneak into a food that has no nuts in the recipe. If you have an allergy, always check labels and ask a grown-up.
More fun facts
- Nuts can get into other foods by accident during harvesting or on shared factory equipment. This is called cross contact.
- Most labels say things like 'contains milk' instead of telling how much of an allergen is inside.
- Food packages in the UK and Europe already list common allergens like egg, peanuts and sesame.
- Once, more than 20 spice products were recalled because they might contain peanuts not listed on the label.
- Experts say reactions to pine nuts and goat's milk happen often enough that they may need warning labels too.
- US scientists at NIST make test samples to help labs check foods for tree nuts.
