Subway Sandwich Formulas Practice Test

Protecting customers with allergies comes down to having a controlled, transparent system for ingredients and how food is prepared. Standardizing ingredients and handling protocols minimizes cross-contact—such as shared utensils, surfaces, or grills—and ensures clear labeling so everyone can quickly see if a sandwich contains gluten or dairy. This creates reliable safety because staff follow the same steps every time and customers can make informed choices. Relying on customers to identify allergens isn’t dependable, since people may not know all ingredients or how something was prepared. Treating all sandwiches as allergen-free is unsafe, and using utensils only for dairy still misses other allergens and the broader need for consistent labeling and prep practices.
