Understanding Food Safety

Food safety is paramount when considering whether it’s safe to eat pizza left out. According to the USDA, perishable food should not be left out at room temperature for more than two hours. Bacteria such as Salmonella begin to grow rapidly at temperatures between 40°F and 140°F, which is considered the “danger zone.”

• Two-hour rule: Ensure that pizza is not left unrefrigerated for more than two hours.
• Refrigeration: Maintain a fridge temperature below 40°F to slow bacterial growth.

The Science Behind Spoilage

Understanding what causes pizza to spoil can help you make safer food choices. Pizza contains ingredients like cheese and meat, which are particularly susceptible to bacterial proliferation.

• Common bacteria: Bacillus cereus and Staphylococcus aureus are typical culprits.
• Smell and appearance: Spoilage signs include an off smell and a change in texture and color.
