Do I need an insulated bag for food delivery?

Usually yes. Food must reach the customer safe. The UK Food Standards Agency says to use an insulated box or cool bag for chilled food, and food-grade packaging.

• India (FSSAI): hot food at 65 C or above, food meant to be eaten cold at 5 C or below.
• England, Wales and Northern Ireland: food that supports bacterial growth at 63 C or above, or at 8 C or below.
• Limits differ by country, so check the rule where you sell.
• Keep hot and cold food apart, and tell customers when to expect delivery.
