You can’t get sick from expired peanut butter. But you should still check the expiration date on your jar of peanut butter before you use it up.

The what happens if you eat expired peanut butter is a question that has been asked many times by many people. Peanut butter can start to lose its flavor after being in the jar for too long. If you’re not careful, it could make you sick.

If it hasn’t been opened after this date, it’s still fine. When peanut butter is opened, it will progressively acquire rancid nut qualities over the following five or six years, until it tastes so terrible that not even the most peanut butter-obsessed kid would eat it. However, you are extremely unlikely to get unwell as a result of it.

So, how can you know if your peanut butter has gone bad?

The most dependable method to determine whether your peanut butter has gone bad is to look at it. A shift in texture from soft and creamy to hard and dry is a typical feature of poor peanut butter. The color of the spread may darken, and the pleasant fragrance may go away. Toss the peanut butter if it starts to smell rancid.

As a result, the issue is whether peanut butter can make you ill. Peanut butter is a delicious spread. Although this lunchtime favorite seems to be harmless, it is one of the high-risk meals that may cause food illness. One of the reasons peanut butter constantly appears to cause foodborne illnesses is that it may contain salmonella.

So, how long can you consume peanut butter once it has passed its expiry date?

An unopened jar of peanut butter (with preservatives) will keep for a year beyond its stated date, whether refrigerated or not. Natural peanut butter has a shorter shelf life in the refrigerator, lasting three to six months beyond its expiration date.

What happens if you don’t keep peanut butter refrigerated?

Consider refrigerating your jar of natural peanut butter if you don’t intend on completing it within a month or if you live in a hot area. If not kept cold, the oils in the peanuts may become rancid. Similarly, if the label specifies that the product be refrigerated after opening, follow the directions.
