Food spoilage is a common concern, especially when it comes to perishable items that can quickly turn unsafe to eat if not handled properly. Spoiled food can cause foodborne illnesses, leading to symptoms like nausea, vomiting, diarrhea, and stomach cramps. It’s essential to be able to identify the warning signs of spoiled food so that you can keep yourself and your loved ones safe. These are a few signs that your food may be spoiled and unsafe to consume.
Off or Sour Odor
A sour, rancid, or unpleasant smell is a clear indication that food has gone bad. Spoiled food can cause foodborne illnesses, and if the food no longer smells fresh, it’s best to discard it immediately. Trusting your sense of smell is one of the easiest ways to identify when food is no longer safe to eat.
Mold Growth
Mold is a common sign of spoilage and can appear on bread, fruits, vegetables, and even on leftovers. Spoiled food can cause foodborne illnesses, and while some mold may be harmless on certain foods like hard cheese, it’s generally unsafe to consume if mold is present, especially on moist or soft foods.
Discoloration
When food changes color, such as meat turning brown or produce becoming overly wilted or discolored, it may indicate it is spoiled. Spoiled food can cause foodborne illnesses, and a shift in color could be caused by bacterial growth or oxidation, both of which can make food unsafe to eat.
Slimy Texture
A slimy or sticky texture, especially in meat, fish, or vegetables, is a strong indicator that food is no longer fresh. Spoiled food can cause foodborne illnesses, and this texture is typically caused by the breakdown of proteins and growth of bacteria.
Unusual Taste
If your food tastes sour, bitter, or generally off compared to its normal flavor, it’s likely spoiled. Spoiled food can cause foodborne illnesses, and never try to “fix” spoiled food by cooking it again—trust your taste buds, and if something tastes wrong, it’s better to discard it.
Soft or Mushy Produce
Fruits and vegetables that become soft or mushy are often overripe or have begun to spoil. Spoiled food can cause foodborne illnesses, and while slightly overripe produce might still be edible in some cases, if they become overly soft or mushy, they should be tossed.

Leaking or Bulging Packaging

Presence of Insects
If you find bugs, larvae, or worms on or inside your food, it’s a sign that it has spoiled or is becoming a breeding ground for pests. Spoiled food can cause foodborne illnesses, and this is especially true for dry foods like grains, flour, and nuts. It’s important to inspect pantry items regularly and keep them stored in airtight containers to prevent contamination.

Curdling in Dairy Products
Milk, cream, or yogurt that has curdled, separated, or formed clumps indicates spoilage. Spoiled food can cause foodborne illnesses, and this change in texture is due to bacterial activity and suggests that the dairy product is unsafe to consume. Always check the expiration date, and if dairy products show signs of curdling or sourness before that date, discard them immediately to avoid any risk.

Cheese That Becomes Hard or Crumbly
Cheese that turns hard or crumbly may have been improperly stored or left too long. Spoiled food can cause foodborne illnesses, and if it has also developed mold or an off smell, it is unsafe to eat. Check for the packaging date and consider the type of cheese when deciding whether to discard.

Cracks in Eggs
Eggs with cracks in the shell are more prone to contamination, as bacteria can enter through the cracks. Spoiled food can cause foodborne illnesses, and if an egg is cracked, it should be discarded, as it could carry harmful bacteria like Salmonella. Always inspect eggs before use and store them properly in the refrigerator to minimize the risk of contamination.
