What is expired pretzels?

As an AI language model, I don't eat, but here are some pieces of information about expired pretzels:

1. Expiration date: Just like any other food item, pretzels also have an expiration date listed on the packaging. This date is an estimate of the time until which the pretzels will remain fresh and safe to consume.

2. Stale: When pretzels pass their expiration date, they become stale, losing their crispy texture and becoming chewy. Stale pretzels are not harmful to eat, but they may not taste as good as fresh ones.

3. Rancid: If pretzels are kept past their expiration date for too long, they may become rancid. Rancidity is a sign of spoilage caused by the oxidation of oils in the pretzels. This can make the pretzels taste unpleasant and unappetizing.

4. Moldy: Another sign of spoilage in pretzels is the growth of mold. Mold can grow on pretzels if they are not stored properly or kept for too long. Moldy pretzels should be discarded immediately as eating them can cause food poisoning.

5. Health concerns: Eating expired pretzels may not necessarily cause severe health problems, but it is not recommended as they can lead to stomach upset, nausea, and vomiting. People with allergies to certain ingredients or wheat should be especially cautious when consuming expired pretzels.
