Blue cheese and allergies: milk and mould

Blue cheese is made from milk and contains mould. Both of these are highly allergenic substances, and allergies to either can cause an upset stomach.

Mould is a common allergen, and most varieties are unsafe for human consumption. When ingested, mould spores can cause an immune system response, resulting in digestive issues. The mould in blue cheese is often deliberately added during the cheesemaking process or can be picked up from other cheeses during ageing.

People with a mould allergy may experience digestive symptoms such as vomiting, diarrhoea, and an upset stomach. In more severe cases, mould allergies can lead to anaphylaxis, a life-threatening reaction characterised by swelling and throat closure.

Milk is also a common allergen, and consuming it can trigger allergic reactions in those who are sensitive. Symptoms of a milk allergy can include diarrhoea, nausea, vomiting, skin rashes, wheezing, shortness of breath, coughing, and chest tightness. These symptoms typically appear within minutes of ingesting blue cheese or other dairy products.

If you suspect you have an allergy to either mould or milk, it is important to consult a doctor for testing and advice. They can help identify the specific allergen and provide guidance on safe food options.

Food poisoning symptoms

Blue cheese is known to upset the stomach because some people are allergic to the mould in it. The digestive response to this allergy can cause vomiting, diarrhoea, and an upset stomach.

Food poisoning is caused by eating contaminated food. Contaminated food is infected with a toxic organism, such as a bacterium, fungus, parasite, or virus. The symptoms of food poisoning include:

  • Diarrhoea
  • Vomiting
  • Fever
  • Stomach pain or cramps
  • Nausea

These symptoms usually start within a few hours of eating contaminated food, but they can also take a few days to develop. It is important to stay hydrated when experiencing these symptoms, as dehydration is the most common complication of food poisoning.

If you are experiencing any of the following severe symptoms, it is important to seek medical attention:

  • Bloody diarrhoea
  • Diarrhoea lasting more than 3 days
  • Fever over 102°F
  • Inability to keep liquids down due to frequent vomiting
  • Signs of dehydration

Blue cheese and inflammation

Blue cheese is made from milk and contains mould, both of which are highly allergenic substances. An allergic reaction to blue cheese can cause inflammation in the body.

If you are allergic to either milk or mould, your immune system will treat the proteins in these ingredients as dangerous and will attempt to fight them off with IgE antibodies. These antibodies trigger mast cells to produce histamine, which leads to inflammation.

Inflammation caused by a food allergy can occur in soft tissue in different parts of the body. Symptoms of a milk allergy can include diarrhoea, nausea, vomiting, skin rashes, wheezing, shortness of breath, coughing, and chest tightness. Mould allergies can cause inflammation in the eyes, throat, sinuses, gastrointestinal system, and skin.

If you suspect that you have an allergy to blue cheese, it is important to consult a doctor, who may recommend allergy testing to determine the cause of the inflammation. In the meantime, it is best to avoid blue cheese and other mouldy cheeses, as well as other dairy products if you suspect a milk allergy.

It is worth noting that not all mould is unsafe for consumption, and some types, such as Geotrichum and Penicillium, are commonly found in cheese. However, for those with a compromised immune system, it is recommended to stay clear of blue cheese and other soft cheeses.

Blue cheese and immune systems

Blue cheese is made from milk and contains mould cultures, such as Geotrichum and Penicillium. These moulds are generally safe for human consumption and are responsible for the distinctive blue veins in the cheese. However, some people may experience an upset stomach after consuming blue cheese due to an allergy to either the mould or milk, or both.

An allergy to mould is not uncommon, and when ingested, it can cause an immune system response. The body's immune system identifies the proteins in mould as harmful and releases IgE antibodies to attack them. This immune response can lead to inflammation in the gastrointestinal system, resulting in symptoms such as vomiting, diarrhoea, and an upset stomach.

Similarly, an allergy to milk is one of the most common food allergies in both children and adults. Consuming even a small amount of milk can trigger an allergic reaction in individuals with this allergy. Symptoms of a milk allergy can include diarrhoea, nausea, vomiting, skin rashes, wheezing, shortness of breath, coughing, and chest tightness.

It is important to note that not all moulds are safe for consumption, and some types of mould can be harmful. People with compromised immune systems, such as those undergoing chemotherapy or pregnant women, should avoid blue cheese and other soft cheeses. If you suspect an allergy to blue cheese, it is recommended to consult a doctor for testing and advice.

Blue cheese and pregnancy

Blue cheese is a popular dairy product known for its blueish hue, strong smell, and flavour. It is often used in salad dressings and sauces or served with fruit, nuts, or other cheeses. However, consuming blue cheese during pregnancy is a topic of concern for many women.

Blue cheese is generally made with mould spores, which are usually safe to consume. However, some people may have allergies to the mould in blue cheese, resulting in digestive issues such as vomiting, diarrhoea, and an upset stomach. Additionally, blue cheese is often made with unpasteurized milk, which carries a higher risk of contamination with Listeria monocytogenes, a bacterium that can cause listeriosis, a foodborne illness similar to the flu or a stomach bug. Listeriosis can have severe consequences during pregnancy, including miscarriage or stillbirth.

Pregnant women are generally advised to be cautious about consuming certain foods, including soft cheeses such as feta and goat cheese. Blue cheese falls into this category and is typically recommended to be avoided during pregnancy. This recommendation is primarily due to the risk of Listeria contamination, especially when made with unpasteurized milk. However, it is important to note that in most states, it is illegal to sell unpasteurized milk or cheese, and proper heating or pasteurization kills the Listeria bacteria.

While blue cheese may be tempting, it is essential for pregnant women to prioritize food safety. It is always advisable to consult with a healthcare professional or a doctor to receive personalized advice and a list of foods to consume or avoid during pregnancy. They can provide guidance based on individual health needs and help ensure a healthy pregnancy.

In summary, blue cheese consumption during pregnancy is generally not recommended due to the potential risks associated with Listeria contamination and mould allergies. However, with proper heating or pasteurization, these risks can be mitigated to some extent. As always, consulting a healthcare professional is the best way to make informed decisions about food choices during pregnancy.
