All 7 detected claims in the English guide have exact source mappings. This automated source comparison is not professional review or a guarantee about an individual food. Claims outside this detector and human review remain separate.
FoodSafety.gov describes the danger zone as 40°F–140°F (4°C–60°C). Refrigerate perishable food within 2 hours, or within 1 hour when exposed to temperatures above 90°F (32°C). These are U.S. household guidelines. FoodSafety.gov.
Time outside refrigeration
FDA applies the room-temperature limit to foods needing refrigeration, including meat, poultry, take-out and leftovers. Put groceries needing refrigeration away promptly after bringing them home. FDA.
Cold storage
Keep the refrigerator at 40°F (4°C) or below and the freezer at 0°F (−18°C). Check the actual temperatures with an appliance thermometer; leave room for cold air to circulate. FDA.
Cooling leftovers
Divide leftovers into shallow containers and refrigerate promptly so they can cool quickly. Do not leave perishable food on the counter while waiting for it to cool. FoodSafety.gov.
Thawing and reheating
Thaw meat and poultry in the refrigerator, rather than on the counter. FoodSafety.gov.
For properly stored leftovers, FoodSafety.gov lists a reheating temperature of 165°F (74°C), checked with a food thermometer. FoodSafety.gov.
Appearance is not proof
FDA warns that food can cause illness even when it looks, smells or tastes normal. Follow storage instructions and time-temperature guidance instead of using a taste test. FDA.
