What is the lowest hot-holding temperature for food. Is it 37c 53c 63c 83c?

The lowest hot-holding temperature for food is 63°C (145°F).

Here's why:

* Food Safety: Temperatures below 63°C allow bacteria to multiply rapidly, increasing the risk of foodborne illness.

* Regulations: Most food safety regulations around the world mandate a minimum hot-holding temperature of 63°C (145°F) to ensure food safety.

Important note: While 63°C is the minimum, it's always best to aim for a temperature closer to 74°C (165°F) for optimal food safety.
