Will grated Kraft Parmesan cheese left on a shelf for 4 years make me sick - was not refrigerated?

It's highly likely that grated Kraft Parmesan cheese left unrefrigerated for 4 years would make you sick. Here's why:

* Spoilage: Unrefrigerated cheese is a breeding ground for bacteria. Over time, these bacteria multiply and can produce toxins that cause food poisoning.

* Mold: Mold growth is common on unrefrigerated food, especially cheese. Mold can produce mycotoxins, which can also cause illness.

* Expiration Dates: Parmesan cheese, even in its original block, has a shelf life. The grated form, with its increased surface area, spoils much faster.

* Kraft Parmesan: Kraft Parmesan is typically a blend of cheese and other ingredients, including cellulose, which can also contribute to spoilage.

Signs of Spoilage:

* Mold: Visible mold growth is a clear sign of spoilage.

* Off odor: The cheese will have a pungent, unpleasant smell.

* Off color: The cheese will look discolored or faded.

* Changes in texture: The cheese will become soft, sticky, or slimy.

Food Poisoning:

Symptoms of food poisoning can include nausea, vomiting, diarrhea, abdominal cramps, fever, and headache.

It's Crucial: Never consume food that shows signs of spoilage, regardless of its expiration date. Throw away any food that has been left unrefrigerated for an extended period.

In short, it's best to err on the side of caution and discard the cheese. Your health is worth it!
