Don’t toss it just yet—check for other signs of spoilage first. It doesn’t matter what kind of yogurt you’re eating—regular, nonfat, or Greek. The signs of spoilage are the same. [2] X Research source
Maybe you aren’t sure if the yogurt smells weird or not. If you see other signs of spoilage, throw it out.
Eating a spoonful is unlikely to make you sick, so don’t worry if you accidentally ate a little bit.
It’s difficult to know just how much shorter the shelf life will be if you leave yogurt out at room temperature, so be sure to evaluate it for signs of spoilage before you dig in. That said, the warmer the temperature, the faster it will spoil. For example, if you left yogurt out in the heat (90 °F (32 °C) and up) for more than an hour, throw it away.
Greek yogurt is just regular yogurt with the whey removed, which results in a thicker consistency. Strained yogurt was popularized by a Greek brand, but it didn’t actually originate in Greece. [11] X Research source
Always store yogurt in the refrigerator at 40 °F (4 °C) to prevent spoilage. You can also freeze yogurt for 1-2 months, although the texture may change. [13] X Research source
How sick you get depends on the type of bacteria you consumed, how much you ate, and whether you’re immuno-compromised or not. Symptoms may last for a few hours to a couple of days. You don’t need to seek medical attention for mild symptoms. To recover quickly, be sure to rest and stay hydrated. Seek medical attention if you experience severe symptoms like: Bloody vomit or stools Extreme abdominal pain Diarrhea that lasts longer than 3 days Severe weakness, dizziness, or lightheadedness Blurry vision or muscle weakness
