What happens if you eat a moldy cake?

In this brief guide, we will answer the query, “What happens if you eat a moldy cake?”. We will also talk more about how to store cakes to increase their shelf life.

What happens if you eat a moldy cake?

There is not much to worry about if you have eaten a moldy cake as it does not cause health issues if consumed in a small amount. But if you have consumed a large amount of cake that had mold in it, then there might be some health issues that you should be concerned about.

The mold spores when ingested can cause irritation to the lining of the intestines and cause gastro-related discomforts.

Some of the symptoms and effects of eating a moldy cake are:

  • Nausea
  • Vomiting
  • Headache
  • Abdominal pain
  • Diarrhea
  • Irritated eyes
  • Itchy nose

It is best advised to completely avoid eating a cake that has mold formed in it as it is not healthy. Some people who are allergic to molds can trigger severe allergic reactions that can be fatal and can cause respiratory ailments such as asthma and sometimes cause death.

What is mold?

Mold is a type of fungus that grows and multiples on moist surfaces, most probably foods including fruit and vegetables, baked goods, meat, and others. 

Mold is always present in the form of spores in a moist environment and is always looking for a host to grow and multiply. Once they come in contact with a food item such as bread, cakes, or fruits, they get the moisture needed for them to grow and start multiplying. 

Molds appear to be fluffy, fuzzy, and dusty on and around the surface of the food but their roots are well engraved on the inside of the food. That is why it is important to completely throw away moldy food than to cut around it to consume as it can potentially be risky.

Mold appears on the outside of the food as white patches, greenish spots, or discolored parts of the food and makes the food look more wet, soft, and moist.

Why does the cake turn moldy?

There are a few reasons why the cake turns moldy. One of the reasons and rather the main reason is that the cake has passed its shelf life by a couple of days. The second reason is the storing practice where the cake has not been covered or wrapped properly to avoid any air or moisture to aid in the growth of mold.

The mold spores are in the air in their natural form all the time. If the cake is not covered or stored properly then the moisture in the cake can act as a favorable habitat for the spores to multiply and form into a mold.

On the other hand, even though the cake is covered and stored properly but still gets moldy because its shelf life is over. The cake is a perishable food item that will deteriorate with time and the natural bacteria and fungi in the food will start to be active and grow as the food goes rancid.

How to store cake for a long time?

Cakes and other baked goods should be properly stored in an airtight container or wrapped with plastic wrap to prolong their shelf life by a couple of days. Cakes depending on the icing and toppings should be either stored in the fridge or at room temperature in the kitchen cabinet or counter.

Cakes last for 1-2 days at room temperature before it starts to lose their texture and moisture and another couple of days before it starts to grow mold around them.

In the case of the fridge-stored cakes, they can last for 4-5 days depending on the container it is stored in and the way it has been wrapped. If wrapped properly and stored in an airtight container they will definitely last 4-5 days and can prolong the shelf life by a few extra days.

If you are thinking of a longer period of time than a couple of days, then freezing the cakes is the best thing to do to preserve the baked goods for at least a few months. While freezing the cakes, they should be double wrapped with plastic wrap and a layer of aluminum foil to protect them from contact with cold air which causes freezer burn.

If stored in an airtight container, it is safe to wrap the container with plastic wrap to keep away from freezer burns that damage the cake. The cake stored in the freezer can last for a period of 6-8 months if stored properly.
