How can cross-contact with allergens be prevented in food prep?

• A. Use separate equipment and prep areas, thoroughly clean and sanitize, and avoid shared utensils for allergen-free items.
• B. Use shared equipment and prep areas for all items.
• C. Rely on customers to avoid allergens.
• D. Just change gloves between tasks.

Answer: (A)

Allergens can spread through direct contact, surfaces, utensils, and equipment, so preventing cross-contact requires physical separation and thorough cleaning. The best approach is to use separate equipment and prep areas for allergen-free items, thoroughly clean and sanitize any surfaces and equipment used, and avoid shared utensils for allergen-free foods. This minimizes the chance that proteins from one food end up on another, addressing both contamination on tools and residues on surfaces.

Changing gloves between tasks helps, but it isn’t enough on its own. If the same cutting boards, utensils, or counters are used for both allergen-containing and allergen-free foods, residues can transfer. Relying on customers to avoid allergens isn’t reliable, since inadvertent exposure can occur before the customer interacts with the food. Proper segregation plus diligent cleaning and sanitation provides a more complete protection against cross-contact.
