Food Safety

Why Perishable Items Must Be Kept at Safe Temperatures. It’s key to keep perishable food at safe temperatures. This prevents foodborne illnesses. The CDC says 1 in 6 Americans gets sick from contaminated food each year. This causes about 3,000 deaths from foodborne illnesses. The temperature “danger zone” is between 40°F (4°C) and 140°F (60°C) where bacteria can multiply rapidly. It’s crucial to keep food out of this range for safety and to comply with health regulations.

Food Safety Rules:

1. Hot food should be above 140°F (60°C).
2. Cold food should be at or below 40°F (4°C).
3. Food left in the danger zone for more than 2 hours should be discarded to prevent illness.

Temperature control is key to food safety. It is a part of programs like Hazard Analysis and Critical Control Points (HACCP). According to research improper temperature control is one of the most common food safety violations across all industries including restaurants and grocery stores.

• A study found that 88.1% of restaurants use thermometers to check fridge temperatures. But, only 13% keep temperature records. This is a big gap in temperature monitoring which can lead to food safety risks.
• Businesses that have strict temperature control not only reduce food borne illnesses but also customer satisfaction. Customers will come back to establishments that prioritize their health and safety through proper food handling.
