Facts

id: F1 claim: Bacteria multiply quickly between 40 and 140 °F, so thawing food must stay at 40 °F or colder, and perishables should not sit at room temperature for more than two hours. confidence: medium date: 2026-11-02 sources: [S1] license: public domain (US government work) checked_on: 2026-11-02
id: F2 claim: Refrigerator thawing takes about a day for every 5 pounds of a large item like a turkey, and a full day even for about a pound of ground meat. confidence: medium date: 2026-11-02 sources: [S1] license: public domain (US government work) checked_on: 2026-11-02
id: F3 claim: Food thawed in the refrigerator can be refrozen without cooking, with some quality loss; ground meat and poultry keep a day or two more, red meat cuts 3 to 5 days. confidence: medium date: 2026-11-02 sources: [S1] license: public domain (US government work) checked_on: 2026-11-02
