Are you tired of playing yogurt roulette? One day it's as fresh as a daisy, and the next, it smells like feet. Fear not, my friends. In this article, we'll be diving deep into the world of yogurt expiration after opening.
The Shelf Life of Opened Yogurt
First things first- how long can opened yogurt last in your fridge before it turns sour (literally)? Generally speaking, 5-7 days is what you should aim for. However, there are many factors that could impact longevity such as temperature fluctuations or contamination from other foods.
Tip: If you're not sure when you opened your container of yogurt but don't want to risk tasting it yourself… just check the expiry date! Subtract a week from that if opened and stored properly in the fridge so there isn't any guesswork required!
Factors That Influence Spoilage
It's difficult to give an exact number for spoilage time because various circumstances can affect longevity:
Container Type
The type of container plays a significant role in prolonging freshness. Paper containers hold less moisture than plastic cups since they absorb excess moisture quickly—plus plastics cause reactions with lactic acid bacteria inside causing naff flavors sometimes! Glass jars technically hold up better but tend to break more easily.
Temperature Fluctuations
Temperature change might decrease shelf life. Try keeping them refrigerated ASAP once home and avoid putting them near any heat source or one with cold drafts (ie windows).
Exposure Time Outside Refrigerator
Leaving your jar out overnight may encourage more rapid growth leading possible health risks - this effect is even worse during summertime when room temperatures higher thus bacteria will multiply faster so keep cool!
Cross Contamination
Cross-contamination will happen over time especially due their use-by dates already being short enough; leaving lids off longer than necessary presents to a high risk leading cause related illnesses if bad bacteria buildup can occur quickly.
Tip: It's critical to avoid cross-contamination by handling the jar with clean hands and using clean utensils.
How to Tell If Yogurt Has Spoiled
- Look for mold or discoloration of any kind.
- Check whether or not there is a fizzy, foamy layer around your yoghurt that looks very runny or watery; this indicates carbon dioxide (CO2) production from bacterial activity – it’s gone seriously off!
- Sniff-test: If you notice gas bubbles rising through the surface or catch an unpleasant smell, it might be best not to eat it! Trust your nose when in doubt though…
Yogurt drinks tend more towards sourness rather than spoilage, so you may find them off at a slightly different flavor level than "bad" yoghurts.
Although we love going 'all-out' on our daily yogurt consumption—be vigilant about expiration dates too!
Note: Properly storing yogurt will result in increased day count but keep note that safety should come first as these guidelines just general ranges often varying time frame depending factors involved!

After purchasing ready-to-eat yogas immediately place into most chilled section fridge 39F°/4°C or below ideally placed away from doors resist urge hours lie slumped sections great door where frequent temperature fluctuations happen causing spoiling rapidly watched slow degradation potency and consistency.

However, when mishandled or exposed for too long during storage due neglecting kindly tips advice offered herein yoghurts expiration becomes a risk—and mold being dispersed around can lead bacteria blooms which become harmful substances over on repeatedly breathing them in could put people at higher risk of respiratory infection – not enjoyable scenarios!
