Follow the 2-hour/1-hour cold storage rule
Discard prepared foods left at room temperature beyond 2 hours—or 1 hour if above 90°F (32°C)—and reheat leftovers to an internal temperature of 165°F (74°C).
📚 Based on Official Guidelines:
Recommended
- Refrigerate cooked foods within 2 hours (1 hour in hot weather)
- Use coolers and ice packs when travelling with expressed milk or prepared foods
- Reheat leftovers thoroughly and stir to distribute heat evenly
Avoid
- Do not refreeze thawed purées or formula once warmed
- Avoid leaving perishable foods in the “danger zone” (40–140°F)
How to apply
- Travel safety: Pack a thermometer with coolers; discard perishable items after 2 hours without refrigeration.
Why it matters: Bacteria multiply rapidly in the danger zone, increasing risk of foodborne illness in infants.
