Safe or Spoiled

 

Expiration dates on packaged food can be confusing. Your nose should clue you in to obvious spoilage. 

  • "Best before" and "use by" dates relate to peak flavor or quality, not to food safety. 
  • "Sell by" dates help the store determine how long to display a product. The product is still good to eat for a period after this date. 
  • Leftovers may be good in the refrigerator for 3 to 4 days.
