Interactive Safety Assessment

"Is it safe to eat?" 3-Step Checklist

Storage dates are guidelines, not laboratory safety tests. Check your food against these 3 primary indicators before consuming:

1. Smell Test (Off Odor) Does the food smell sour, pungent, rancid, or like ammonia?

2. Visual Test (Mold / Discoloration / Slime) Is there visible fuzz, gray/greenish tint, or unexpected surface slime?

3. Storage & Packaging History Was the food left at room temperature for over 2 hours or packaging damaged?

✅ No signs of spoilage selected

If handled properly and within the recommended window, the food appears safe to proceed. Always use good judgment.
