Rancid olive oil tastes bitter, sour and/or stale and lacks the peppery, sharp taste of fresh olive oil. Usually, there are no adverse effects to consuming bad olive oil, unlike some other food products that have gone off.
How do I know if my olive oil is bad?

How long does olive oil stay good after opening?
18-24 month
Once bottled, olive oil has an 18-24 month shelf life so extra virgin olive oil should be purchased within 12 to 18 months of its harvest date and should be used up within six months of opening. We recommend using up the oil within 30 to 60 days upon opening.

Should extra virgin olive oil be refrigerated after opening?
Even after being opened, refrigeration is not necessary as long as stored properly.

How do you store extra virgin olive oil after opening?

Expired Vegetable Oil

Why does olive oil turn cloudy?
Because olive oil is minimally processed, it contains more polyphenols than other oils. (Canola oil is usually processed to the point where very few of these compounds remain.) Polyphenols are soluble in oil only at room temperature. As the temperature decreases, they begin to separate out, making the oil cloudy.
