It is probably ok, but why would you bother?
Are you that hard up for food that you'll eat something thats been sitting in the fridge for almost half a year?

I made it fresh from my garden. no exp. dates.

lol

and no, olive oil is not a preservative. it can go bad. benzine-tasting bad.

however...I did consume half a jar of store-bought pesto that was ~2.5 years old, after it's original open date. I am still alive 2 years later, so I can safely say that there were no ill effects. although I'm starting to doubt the quality of that particular pesto...

Sure, but it's still like 6 months old. Just make a new batch.
If you have more than you need, then freeze it.

Some things preserved in olive oil (like the peppers you talked about) are heat-treated after canning/jarring to kill any bacteria/spores. Olive oil preserves the food by protecting it from oxygen. However, not all bacteria/spores require oxygen to thrive. In fact, some will only thrive in an environment devoid of oxygen.

The garlic in your pesto can harbor botulism. Had I seen this before you ate your pesto I would recommend a thorough heating before consumption. Now that you went ahead and tossed down, I would recommend keeping a phone nearby with 911 on speed dial. Botulism can strike very quickly, so good luck with that.

As a rule, don't eat any leftovers that are over a week old.

Im still alive as of....right now.

"In the United States an average of 110 cases of botulism are reported each year. Of these, approximately 25% are foodborne" So thats like 28 cases per year. Slim to none.

think you can make some slices, mount them on a slide and take pics through a scope? that would reveal whatever beasties you have working their way through your system ;)

I am having trouble imagining that you moved from one city to another city and took six month old left over pesto with you.

I did! It was good pesto man! I took the pickles too! and some cans of tuna fish and some soup.

Groceries are expensive man. I don't know how minimum wage ppl live.

Just because the incident rate is low doesn't mean it won't happen to you. Dude, the pesto was 5 months old... Throw that shit away and make some fresh.

Hehe...good to know. I've never waited more than a week though. Of course I wouldn't eat it without proper heating. We used it to make a chicken-spinach-pesto sauce pizza. Sounds odd, by my fiancée is allergic to tomato sauce. :( It was still tasty though!
