What Happens If You Eat Expired String Cheese?

String cheese is a fun, portable snack that’s loved by kids and adults alike. But can you get sick from eating string cheese past its expiration date? Here’s a detailed look at what happens if you eat expired string cheese.

Can String Cheese Go Bad?

Yes, absolutely – string cheese can definitely go bad past its expiration date. Like any dairy product, string cheese can spoil due to bacteria growth.

The main bacteria of concern in cheese is lactobacillus. As this bacteria multiples, it causes the proteins and fats in the cheese to break down. This leads to souring, discoloration, development of slime, mold growth and unpleasant odors.

So signs that your string cheese has spoiled include:

  • Mold growth – may appear as fuzzy white, blue, green or black spots
  • Slimy texture – cheese should not be sticky or slimy
  • Sour smell – should still have a mild dairy scent
  • Discoloration – excessive drying, crumbling or unnatural colors

If you notice any of these signs, it’s best to discard the string cheese.

Is It Safe to Eat Expired String Cheese?

The answer really depends on how expired we’re talking and how the cheese was stored.

Here are some general guidelines on expired string cheese:

  • Unopened string cheese is generally safe to eat 1-2 weeks past the printed sell by or expiration date, provided it was stored properly in the fridge.
  • Opened string cheese should be eaten within 1 week of opening. It’s best to discard any opened string cheese after 7-10 days.
  • If your string cheese is past its expiration date, inspect it closely before eating. Use your best judgment – if there are any signs of spoilage, it’s better to be safe than sorry.

The shelf life does depend on storage conditions. If stored in the back of the fridge in original packaging, unopened string cheese lasts longer.

  • Upset stomach – symptoms like nausea, vomiting, diarrhea, abdominal cramping
  • Food poisoning – from bacterial toxins like those produced by staph, listeria, e. coli, salmonella
  • Allergic reaction – some people are sensitive to molds and can have an allergic response
  • Illness – Listeria, E.coli and Salmonella are risks if cheese was contaminated and bacteria grew. Can cause fever, chills, bloody stool.

Groups at higher risk for severe illness include pregnant women, children, the elderly and those with weak immune systems.

  • Keep unopened string cheese in its original packaging until you are ready to eat it. The plastic packaging helps protect it.
  • Once opened, rewrap tightly in plastic wrap or a zip top plastic bag, squeezing out excess air.

  • Freeze for long term storage. With proper wrapping, string cheese can be frozen for 6-8 months. Thaw overnight in the fridge before eating.

Following these simple storage guidelines helps preventstring cheese from going bad prematurely.
