Cross-contamination is where the exam checks whether you can picture a kitchen: what goes on which shelf, which cutting board is which color, what happens when a guest with an allergy orders. This quiz covers storage order, color coding, allergen cross-contact, date marking and FIFO, produce washing, wiping cloths, and chemical storage. It is one topic from our full 30-question practice test.
How it works: up to 15 multiple-choice questions on this one topic, or a quick 10. Answer, read the explanation, and use the link to review the guide behind it. Questions and answer order are shuffled every time, and your answers stay in your browser.

A practice test isn't the card. The card comes from an accredited course and its test. Both of these courses are ANAB-accredited, which California, Texas, and Illinois accept. They don't count everywhere: Washington, Oregon, Utah, Florida, Ohio, Southern Nevada (Las Vegas), and a few California counties require their own or state-approved programs, so check your state's rule first.

Frequently Asked Questions
What goes on the top shelf of the refrigerator?
Ready-to-eat foods go on top. Below them, in order: seafood, then whole cuts of beef and pork, then ground meats and ground seafood, with poultry on the very bottom. The rule is simple — nothing stored above can drip onto food that won't be cooked again.
Which cutting board do I use for raw chicken?
Use a board dedicated to raw meat and poultry — the common color convention is yellow for raw poultry and red for raw meat — and a separate one (often green) for produce and ready-to-eat foods. Wash, rinse, and sanitize the board and knife between uses if you only have one.
A customer says they have a peanut allergy — what do I do?
Take it seriously and tell the person in charge. Prevent cross-contact: use clean, sanitized equipment and utensils, wash your hands, verify ingredients with the kitchen, and never guess. Allergen proteins aren't destroyed by cooking, so "just cooking it a little more" doesn't help.
How long can I keep cooked leftovers in the refrigerator?
Date-mark refrigerated ready-to-eat TCS food and use or throw it out within 7 days, stored at 41°F or below. Day 1 is the day you prepped or opened it — not the day after.
What's the difference between cross-contamination and cross-contact?
Cross-contamination is the transfer of harmful bacteria — like raw chicken juices dripping onto salad. Cross-contact is the transfer of allergen proteins from one food to another. The key difference: cooking kills bacteria but does not destroy allergens.
