The safety of the yogurt depends on several factors, including the room temperature, the duration it was left out, and whether the container was opened or sealed. In general, leaving yogurt at room temperature for an extended period can allow harmful bacteria to grow, which may lead to foodborne illnesses.
Since you mentioned that the container was sealed, it might have provided some level of protection against contamination. However, it's essential to exercise caution to ensure your safety.
Here's what you can do:
Check the Smell and Appearance: First, open the container and examine the yogurt's smell and appearance. If it looks and smells fine, it may still be safe to consume.
Check for Mold or Unusual Texture: Look for any signs of mold or unusual texture on the surface of the yogurt. Mold growth is a clear indication that the yogurt has spoiled and should be discarded.
Taste Test: If everything looks and smells okay, you can perform a small taste test. If the yogurt tastes sour, off, or different from its usual flavor, it's best not to eat it.
Consider the Risk: Keep in mind that yogurt left out for 8 hours at room temperature is at higher risk of bacterial contamination. This is especially true if the room was warm. If you have a weakened immune system, are pregnant, elderly, or have young children, it's safer to discard the yogurt to avoid any potential health risks.
When in doubt, it's better to err on the side of caution and discard the yogurt. Consuming spoiled food can lead to food poisoning or other health issues. It's crucial to follow proper food safety practices to reduce the risk of foodborne illnesses. In the future, try to refrigerate perishable foods promptly to maintain their safety and quality.
