Left out overnight

Left the chicken, rice or milk out overnight? The USDA 2-hour rule applied to 269 perishable foods, A–Z, with what to do next.

The rule is the same for every food here: perishable food is safe at room temperature for 2 hours, or 1 hour above 90°F (32°C). Overnight is always too long. Each page explains why for that food and how long it keeps once refrigerated.
