Important Considerations for Dairy Allergies: The Risk of Cross-Contamination

While the sauce itself is dairy-free, individuals with severe milk allergies must be aware of the risk of cross-contamination. Subway's kitchen environment is shared with dairy-containing items like cheese and creamy sauces. This risk arises from shared utensils, preparation surfaces, and employee gloves.

How to Minimize Cross-Contamination Risk

To reduce cross-contamination risk, inform staff of your dairy allergy, request fresh gloves, ask for ingredients from fresh containers, use unwrapped knives, confirm your sauce choice, and observe the preparation process.
