Frequently Asked Questions

What's the difference between expiration and best quality dates?

Over time, the quality of a frozen pizza can degrade due to freezer burn and changes in texture and flavor. While the pizza may still be safe to eat after the expiration date if stored properly, the taste and texture may not be optimal. It's important to distinguish between safety (based on expiration date) and quality (based on taste and texture).

How can I tell if Frozen Pizza Opened has gone bad?

If a frozen pizza that has been opened has gone bad, look for signs of freezer burn like ice crystals, discoloration, or a dried-out appearance. Check for any off odors or a sour smell. Lastly, if the texture feels mushy, slimy, or overly dry, it's best to discard the pizza to avoid potential foodborne illness.

What are the food safety risks?

Frozen pizzas can pose foodborne illness risks if not handled properly. Common pathogens associated with frozen pizzas include Salmonella and Listeria. To reduce the risk of foodborne illness, ensure the pizza is cooked thoroughly to the recommended temperature. High-risk scenarios include thawing and refreezing the pizza multiple times.

What are some pro storage tips?
