If you're unsure about the freshness of your food, there are a few tell-tale signs you can look for.
First, take a look at the expiration date on the packaging. This is usually a good indicator of how long the food will stay fresh. If the food is past its expiration date, it's probably not safe to eat.
Another way to tell if food is fresh is by looking at its appearance. Fresh fruits and vegetables should be brightly colored and free of blemishes or bruising. If meat or fish looks dull or discolored, it's probably not fresh.
Finally, you can use your sense of smell to determine if food is still fresh. Food that has gone bad will often have a sour or unpleasant odor. If you're unsure whether something smells okay, it's probably best to throw it out.
If you're ever in doubt about the freshness of your food, err on the side of caution and throw it away. It's better to be safe than sorry when it comes to eating expired or spoiled foods!
