Can You Get Food Poisoning from Uncrustables

Food poisoning is one of the most common reasons that people seek medical treatment and is often misunderstood by the public at large. Understanding whether you are likely to get food poisoning can help you avoid it.

 Can You Get Food Poisoning from Uncrustables?

It’s possible to get food poisoning from Uncrustables, but it’s unlikely.

Uncrustables are made with real bread and packed in a sealed wrapper. They’re not frozen, but they do have a long shelf life. That means that they can stay unrefrigerated for up to 30 days without spoiling. But if you don’t store them properly, there could be some trouble.

Food Poisoning: What Is It?

Food poisoning is the term used when a person eats contaminated food or drinks contaminated water and suffers from nausea, vomiting and diarrhea within 24 hours of consumption. While most cases resolve on their own within two days, some types of food poisoning can cause serious illness or even death if left untreated.

However, many parents are concerned about the safety of this product because it contains peanut butter, which is one of the top eight allergens.

Can you get food poisoning from Uncrustables? The answer is yes — but only if your child has an allergy to peanuts and eats an Uncrustable without washing his hands afterward.

The concern over allergies prompted an attorney to file a class action lawsuit against Kraft Foods Group Inc., claiming that the company failed to put warning labels on its packaging or in stores to alert consumers that some Uncrustables contain peanut butter.

Can you get food poisoning from Uncrustables?

Yes, you can get food poisoning from Uncrustables.

In the past few years, some parents have reported getting sick after eating peanut butter and jelly sandwiches. The reports include vomiting and diarrhea. The CDC has investigated several of these cases and has not been able to find a common source of infection.

The illnesses have occurred at different times of year, in different states, and in different locations within each state. They also involve children who attend different schools and whose parents work at different jobs.

However, some of them do share some common characteristics:

  • Most of the children were around 6 years old.
  • The children had no other obvious risk factors for foodborne illness (for example, they did not attend day care or have recently traveled out-of-state).
  • The children ate their Uncrustables at school or day care centers on the same day that they became ill (and before anyone else became ill).

 What’s in a Smucker’s Uncrustable?

The Smucker Company, which makes the Uncrustables brand of sandwiches, has received numerous complaints about mold and mildew growing on the crusts of the peanut butter or grape jelly sandwiches.

These complaints have led to a class action lawsuit against The Smucker Company for violating consumer protection laws in California, Massachusetts and New Jersey. The lawsuit alleges that Uncrustables are not fit for human consumption because they contain ingredients that cause food poisoning.

In some cases, eating these sandwiches has resulted in serious illnesses for children and adults alike.

The sandwich consists of two slices of bread with a filling between them. In most cases, this filling is made from peanut butter or grape jelly. But there are other ingredients as well — including salt and sugar — that can cause problems if they aren’t properly handled during processing and packaging.

What’s in a Smucker’s Uncrustable?

  • According to Smucker’s website, each 11-ounce Uncrustable sandwich contains:
  • Two slices of bread (wheat or white)
  • Peanut butter (or grape jelly) filling
  • Sugar (to sweeten the peanut butter/jelly)

How Long Do Smucker’s Uncrustables Usually Stay Good For?

Smucker’s Uncrustables are available in both a lunchable and sandwich format. Each variety has a shelf life of 30 days after opening.

If you have any leftovers from your Uncrustables, they should be stored in a refrigerator and eaten within three days. Otherwise, the peanut butter and jelly will spoil quickly.

How Long Can You Keep Smucker’s Uncrustables Before They Go Bad?

Smucker’s Uncrustables are made with natural ingredients, but they will eventually go bad if not properly stored in the refrigerator. If you have leftover Uncrustables after school or work, it’s important to store them properly so they won’t spoil before you can eat them. The shelf life of an Uncrustable is 30 days after opening when stored at 45 degrees Fahrenheit or below in the pantry or refrigerator. If your Uncrustables start to develop mold or begin to smell bad, throw them away immediately, as they could make you sick if consumed!

How Long Can Uncrustables Sit Out

Uncrustables are sandwiches filled with fillings like turkey, roast beef and ham. They’re made by Sandwich Generation, a company that makes other bread-based foods such as muffins and cookies. Uncrustables come in single-serving sizes, which you can buy at most grocery stores or online. Each sandwich is individually wrapped and sealed in a plastic bag. The instructions on the package suggest that you eat them within three days of purchasing them, but it’s not safe to leave them out for more than one day.

How long can uncrustables be left out?

When left out, how long do Uncrustables last?

Your kids think that any food item found in the fridge or freezer will last indefinitely out on the kitchen counter. This is kidthink at its most basic. For some reason they believe the opposite about fresh produce, like a carrot from the garden or an apple from a tree – get those things in the deep freeze before they poison us all! That seems to be what is in the mind of a child.

Nobody makes their own sandwiches anymore, not since Betty Crocker left the building. We either get made at the deli or buy them in the freezer section. Many kids are suspicious of anything their mother makes. 

Since uncrustables are typically located in the freezer aisle, it follows that they are frozen meals that require the same storage conditions at home as they do in the store. Patiently explain this to your kids – even though it will do no good.

Don’t try licking them. Thaw them.

The uncrustable cannot be microwaved per package instructions; therefore, wait till it thaws.

Two to three hours is fine for leaving uncrustables out at room temperature.

When the uncrustables are defrosted and ready to consume, the clock starts ticking on this time limit.

The recommended shelf life for virgin Uncrustables is six to eight hours.

The best flavor and quality, however, are likely to be achieved by adhering to the two-hour safety guideline.

When a processed object is left out for too long, what will happen to it?

It becomes inedible – either because it spoils or it becomes too mushy. Or the dog gets it.

The shelf life of uncrustables is drastically reduced after thawing.

The two wisest options are eating them immediately or leaving them in the freezer.

Safety Concerns

Sandwich Generation recommends eating Uncrustables within three days of purchasing them because they contain mayonnaise and other ingredients that can spoil quickly if left out too long. The company also warns against eating any expired product since it may not be safe to eat once its shelf life has passed


Most food poisoning scenarios occur when food is stored in the fridge or freezer and then not eaten by its expiration date. The biggest way to avoid food poisoning is to never thaw or cook food that has been frozen. Uncrustables, however, are an exception. They do not require cooking or a refrigerator, so they are safe from bacteria growth by design.
