Is expired kefir safe to drink?
Quick Answer
No
Expired kefir may contain harmful bacteria or yeast that could cause food poisoning. It’s best to discard it if it’s past its expiration date.
What Is It?
Kefir is a fermented milk drink similar to a thin yogurt that is made from kefir grains, a specific type of mesophilic symbiotic culture. It has a tart, sour taste and a slight ‘fizz’, due to carbon dioxide, the end product of the fermentation process.
How to Tell
Signs of expired kefir include a strong sour smell, change in color, or presence of mold. If the kefir has separated into a thick, cheese-like layer and a lot of liquid, this is another sign that it has gone bad.
Why It Can Be Risky
Drinking expired kefir can pose several health risks.
- Food poisoning: The harmful bacteria or yeast that may grow in expired kefir can cause symptoms like nausea, vomiting, diarrhea, and stomach cramps.
- Allergic reactions: If you’re allergic to molds, consuming expired kefir that has mold could trigger an allergic reaction.
Safe Method?
Always check the expiration date before consuming kefir. If it’s past its date, or if it shows signs of spoilage, it’s best to discard it.
Can You Just Cut It Off?
If the kefir is only a day or two past its expiration date and doesn’t show any signs of spoilage, it may still be safe to consume. However, it’s always best to err on the side of caution.
Safe Alternatives
