7 Foods That Could Have Hidden Mold (And How To Prevent It)

Discovering mold on your food is always a disappointing experience, especially when you were looking forward to a meal. While some mold is obvious, it often hides in places where you might not think to look. Mold can produce toxins that are harmful if eaten, so staying vigilant is important for your health.

By understanding the truth about mold, you can prevent food waste and keep your family safe.

Liquids and semi-solid foods like yogurt must be tossed at the first sign of mold. Because of it's soft structure, mold can spread throughout the yogurt, even if it's only visible on the top layer.

Store yogurt in the fridge in a sealed container, and throw it away if you notice visible mold or off-putting odors.

Berries are prone to mold because of their soft skins and high moisture content. Mold often starts deep inside the cluster or in the tiny crevices of raspberries and blackberries. To prevent this, never wash your berries until right before you eat them.

Moisture is the biggest trigger for fungal growth. Store them in a container lined with a dry paper towel to absorb any excess humidity and keep them fresh for longer.

Tomato paste is a common culprit for hidden mold because it often sits in the fridge half used. Once the can is opened, the acidity is not enough to stop mold from growing on the exposed surface.

To prevent this, you can transfer the leftover paste to a small glass jar and top it with a thin layer of olive oil. The oil creates a seal that blocks out air and keeps the paste fresh.

You might see a clean slice of bread on top, but mold spores often travel through the porous structure of the entire loaf. The mold on the surface is only part of the problem, so cutting off a moldy section is not enough to keep you safe.

To extend the life of your bread, keep it in a cool and dry place or store it in the freezer.

Many people assume the high sugar content in maple syrup protects it, but mold can actually grow on the surface or around the cap. This usually happens when the bottle is kept in the pantry after being opened.

Once you break the seal, you should always store your syrup in the refrigerator. If you see any cloudy film or floating spots, it's best to discard the bottle to avoid any risk of illness.

Soft cheeses such as brie and blue cheese are made with safe types of mold, but they can still develop harmful mold as well. Soft cheeses have a high water content, allowing mold to thrive, even in the fridge.

If you notice fuzzy or off-colored spots on your cheese, the safest thing to do is to discard the whole thing.

Mushrooms are tender vegetables that are susceptible to spoilage within a few days or a week in the fridge. The softer the variety of mushroom, the shorter their shelf life.

If you notice a slimy or mushy texture, this means mushrooms are starting to spoil. They should be discarded if they begin to develop fuzzy white or grey mold spots.
