How we tested spoilage

We stored our unopened frozen pizza in the freezer at 0°F (-18°C) for a total of 180 days to test for spoilage. After this period, we removed the pizza and inspected it closely. We noted the presence of frost and ice crystals on the surface, which indicated potential freezer burn. Upon opening the packaging, we detected a faint off smell that was not typical of fresh pizza. The toppings appeared discolored, and the crust had a slightly altered texture. To verify safety, we heated a small portion to 165°F (74°C) and observed no significant improvement in quality. Ultimately, we decided to discard the pizza due to these spoilage signs.

Frequently Asked Questions
