Moulding on food is a common problem that most people have encountered at some point in their lives. Mould, which is a type of fungus, grows on food when it is exposed to air and moisture. While some types of mould are harmless, others can be dangerous to your health. In this blog post, we will explore the causes, dangers, and prevention of mould in food.
Mould or Mold, Which is correct?
Both "mould" and "mold" are correct spellings of the same word. The spelling "mould" is more commonly used in British English, while "mold" is the preferred spelling in American English. However, both spellings are widely recognized and accepted in both dialects of English.
Common Foods which Easily Attract Mould
Mould is a type of fungus that can grow on various foods. Some of the most common foods that are susceptible to mould growth include:
- Bread: Mould can grow on bread quickly if it is not stored properly.
- Cheese: Soft cheeses such as blue cheese, Roquefort, and Camembert are particularly prone to mould growth.
- Nuts: Nuts such as peanuts, almonds, and cashews can develop mould if they are not stored correctly.
- Fruit: Fruit such as strawberries, grapes, and raspberries are often prone to mould growth.
- Vegetables: Vegetables such as tomatoes, peppers, and cucumbers can develop mould if they are not stored in a cool, dry place.
- Meat: Processed meats such as salami and ham can also develop mould.
It is important to be aware of the signs of mould growth on food and to discard any food that shows visible signs of mould. Mould can produce allergens and toxins that can cause food allergies or other health problems, so it is best to avoid consuming mouldy food.
Causes of Mould on Food
Mould spores are present everywhere in the air and on surfaces, including on the food we eat. The growth of mould on food is caused by a combination of factors, including:
- Moisture: Mould needs moisture to grow, so foods with high water content are more likely to become mouldy. This includes fruits, vegetables, and bread.
- Warmth: Mould thrives in warm environments, so food that is stored in warm areas or at room temperature is more likely to become mouldy.
- Oxygen: Mould requires oxygen to grow, which is why it is more common in food that is exposed to air.
- Time: The longer food is left unused, the more likely it is to develop mould.
Dangers of Mould on Food
While some types of mould on food are harmless, others can be dangerous to your health. Some of the dangers of eating mouldy food include:
- Allergic reactions: Some people are allergic to certain types of mould and can experience allergic reactions when they consume mouldy food.
- Toxins: Some types of mould produce mycotoxins, which can cause serious health problems such as liver damage, cancer, and neurological disorders.
- Infections: Mould can cause infections in people with weakened immune systems, such as the elderly, children, and people with chronic illnesses.
Mould and Food Allergy
Moulds are a type of fungus that can grow on a variety of different surfaces, including food. Some people may be allergic to certain types of moulds, which can cause an allergic reaction when they consume contaminated food.
The symptoms of a mould allergy can vary, but they may include:
- Itchy or watery eyes
- Runny nose
- Wheezing or shortness of breath
- Skin rash or hives
- Swelling of the lips, tongue, or throat
In severe cases, a mould allergy can cause anaphylaxis, which is a life-threatening allergic reaction that requires immediate medical attention.
To prevent a mould allergy reaction, it's important to avoid foods that are contaminated with mould. This includes foods such as cheese, bread, mushrooms, and other foods that have visible mould growth or a musty odour. It's also important to properly store and handle food to prevent mould growth.
If you suspect you have a mould allergy, it's important to speak with your healthcare provider. They may recommend allergy testing and can provide advice on how to manage your allergy symptoms.
Food Allergy Test
A food allergy test is a medical test that can help diagnose food allergies. Food allergies occur when the immune system mistakenly identifies a certain food as harmful and triggers an allergic reaction. Symptoms of a food allergy can range from mild to severe and can include hives, swelling, itching, and difficulty breathing.
There are several different types of food allergy tests available, including:
- Skin prick test: A small amount of the suspected food allergen is placed on the skin, and the skin is then pricked with a needle. If the skin reacts with swelling or redness, it may indicate a food allergy.
- Blood test: A blood sample is taken and tested for the presence of IgE antibodies, which are produced by the immune system in response to an allergen.
- Elimination diet: This involves removing suspected allergenic foods from the diet and then slowly reintroducing them to see if symptoms return.
- Oral food challenge: This involves consuming a small amount of the suspected allergenic food under medical supervision to see if an allergic reaction occurs.
It's important to note that food allergy tests are not always 100% accurate and should be interpreted by a healthcare provider. In addition, food allergy tests should not be used to diagnose food intolerances, which are different from food allergies and involve a different part of the immune system. If you suspect you have a food allergy, it's important to speak with your healthcare provider for proper diagnosis and treatment.
Treatment after Eating Mouldy Food
If you have accidentally eaten mouldy food and are experiencing symptoms of an allergic reaction or food poisoning, it is important to seek medical attention immediately. Some common symptoms of mould-related illnesses include:
- Allergic reactions: hives, swelling, itching, difficulty breathing
- Food poisoning: nausea, vomiting, diarrhoea, abdominal pain, fever
If you experience any of these symptoms after consuming mouldy food, contact your healthcare provider or go to the nearest emergency room right away.
In some cases, your healthcare provider may recommend antihistamines to alleviate symptoms of an allergic reaction, or prescribe antibiotics or other medications to treat food poisoning. It is important to follow their recommendations and take any prescribed medication as directed.
To prevent the risk of consuming mouldy food in the first place, it is important to properly store and handle food. This includes keeping food in airtight containers, refrigerating perishable items promptly, and discarding any food that shows visible signs of mould.
Why Getting Mould on Refrigerated Foods?
Mould can grow on refrigerated foods because even though refrigerators help to slow down the growth of mould and bacteria, they do not completely stop it. In fact, some types of mould can still grow in a refrigerator's cool, damp environment.
This can happen for a few reasons:
- The temperature inside the refrigerator is not cold enough: The ideal temperature for a refrigerator is between 0-5 °C (32-41 °F). If the temperature is higher than this, it can encourage mould growth.
- The food is not properly sealed: Mould spores can travel through the air and contaminate nearby food. If food is not properly sealed, it can be exposed to mould spores and begin to grow mould.
- The refrigerator is not cleaned regularly: If there are spills or food particles left in the refrigerator, they can provide a breeding ground for mould and bacteria to grow.
To prevent mould growth on refrigerated foods, it is important to keep the refrigerator clean and at the proper temperature. Additionally, food should be stored in airtight containers or sealed bags to prevent contamination from mould spores. Any food that shows signs of mould or spoilage should be thrown away immediately.
Prevention of Mould on Food
Preventing mould on food is important to protect your health and ensure that your food is safe to eat. Here are some tips to prevent mould on food:
- Store food properly: Store food in airtight containers or in the fridge to prevent mould growth.
- Check food regularly: Check food regularly for signs of mould, and discard any mouldy food.
- Use food quickly: Use food quickly to prevent it from going bad and developing mould.
- Keep surfaces clean: Keep surfaces clean and dry to prevent the growth of mould.
- Use mould inhibitors: Some food preservatives can inhibit the growth of mould, such as vinegar and citric acid.
Moulding on food is a common problem that can have serious health consequences. It is caused by a combination of moisture, warmth, oxygen, and time. While some types of mould are harmless, others can be dangerous to your health. Preventing mould on food is important to protect your health and ensure that your food is safe to eat. By following these tips, you can reduce the risk of mould on food and keep yourself and your family safe.
