Bacteria, mould, and microorganisms
Cheese is a dairy product that can be a delightful treat, but it can also cause vomiting and other adverse health effects if contaminated or spoiled. Bacteria, mould, and microorganisms play a central role in this process of deterioration, and understanding their role is essential to prevent unpleasant experiences with cheese.
Cheese is made by separating milk proteins from the watery part, called whey, and then ageing the curds for various durations, depending on the desired variety. This ageing process, if not adequately controlled, can become a breeding ground for harmful bacteria, leading to food poisoning. Raw, soft cheeses made from unpasteurized milk are particularly susceptible to harmful bacteria like E. coli, Listeria, and Salmonella. However, even pasteurized cheeses can cause food poisoning due to contamination during processing or distribution.
Mould and microorganisms can also contaminate cheese, rendering it unsafe for consumption. Improper storage conditions, such as incorrect temperature and humidity levels, facilitate the growth of these contaminants. Cross-contamination can also occur when using utensils or cutting boards that haven't been properly cleaned. Additionally, improper handling of cheese, such as touching it with bare hands, can introduce bacteria and other microorganisms, increasing the risk of spoilage and potential health hazards.
The signs of spoilage in cheese can vary depending on the type of cheese, its age, and storage conditions. However, some general indicators of spoilage include the presence of mould, an expired product date, or noticeable changes in texture, colour, or smell. When cheese goes bad, consuming it can lead to a range of unpleasant symptoms, including mild effects like an upset stomach, diarrhoea, and nausea, to more moderate symptoms such as fever, abdominal cramps, and vomiting.
To minimize the risk of encountering spoiled cheese, it is essential to practice proper storage and handling. This includes storing cheese at the appropriate temperature and humidity levels, using clean utensils and cutting boards, and refraining from touching the cheese with bare hands. Additionally, it is advisable to check the product's expiration date and inspect the cheese for any visible signs of spoilage before consumption.
In conclusion, bacteria, mould, and microorganisms are the primary culprits behind cheese spoilage and the associated health risks, including vomiting. By understanding their role and taking the necessary precautions, cheese lovers can continue to enjoy this dairy delight without unpleasant consequences.

Pasteurized cheese food poisoning
Cheese is a dairy product that can sometimes cause vomiting and other symptoms associated with food poisoning. However, it's important to note that not all cheese is created equal when it comes to food safety.
Firstly, let's differentiate between pasteurized and unpasteurized cheese. Pasteurization is a process that involves heating milk to a high temperature for an extended period to kill harmful bacteria such as E. coli, Listeria, Salmonella, and Campylobacter. These bacteria can cause serious foodborne illnesses, and in the case of Listeria, can lead to a harmful infection called listeriosis. Soft cheeses, such as queso fresco and Brie, are more prone to contamination due to their high moisture content and lack of an aging process that could otherwise kill harmful bacteria.
Unpasteurized cheese, also known as raw cheese, has been linked to food poisoning outbreaks. In 2024, the Centers for Disease Control and Prevention (CDC) reported a multi-state outbreak of E. coli infections linked to unpasteurized cheese, resulting in hospitalizations and serious health complications. While the sale of unpasteurized milk across state lines is illegal in the United States due to health risks, this restriction does not extend to raw cheese. As a result, health officials urge consumers to avoid consuming unpasteurized dairy products, including raw cheese, to minimize the risk of bacterial infections.
On the other hand, pasteurized cheese is generally considered safer as the pasteurization process eliminates harmful bacteria. However, it's important to understand that pasteurized cheese can still cause food poisoning due to contamination during processing or distribution. This type of food poisoning is less likely to be caused by bacteria and may be due to other factors introduced during these stages.
If you experience vomiting or other symptoms of food poisoning after consuming cheese, it is advisable to seek medical attention. It is also recommended to follow good hygiene practices and ensure that cheese is properly stored and handled to minimize the risk of contamination.
In summary, while pasteurized cheese is generally safer than unpasteurized cheese in terms of bacterial infections, it can still cause food poisoning due to contamination during processing or distribution. The type of symptoms experienced may vary depending on the source of contamination. To minimize the risk of foodborne illnesses, it is advisable to opt for pasteurized dairy products and practice proper food handling and storage.

Sanitation issues in cheese production
Good sanitation is critical for producing safe, high-quality cheese. The FDA Food Safety Modernization Act (FSMA) mandates sanitation practices that include proper training of personnel in food safety, food hygiene, and cleaning and sanitation procedures. High sanitation standards are essential in the cheese industry to prevent foodborne illnesses caused by contaminated dairy products.
One of the key aspects of sanitation in cheese production is the separation of areas based on the risk of contamination. This is known as hygienic zoning, where physical barriers, controlled transitions, and sanitary practices are used to minimize the risk of contamination. For example, areas that receive and store milk should be treated as high-risk zones, with personnel following specific sanitary protocols when entering and exiting these areas.
Another important consideration is the proper training of employees in personal hygiene and basic sanitary practices. Clothing worn in cheese processing areas should be separate from other areas to prevent cross-contamination. Open wounds should be covered, and employees should not work in production areas while sick or injured. Regular microbial analysis is also necessary to ensure that cleaning processes are effective and to identify any lapses in sanitation.
Inadequate cleaning and sanitation can lead to the contamination of milk and cheese products. Milk can become contaminated with microorganisms from the farm environment, feedstuffs, and milking and processing equipment. Contaminants can also access the cheese during manufacture and aging, resulting in defects and food safety concerns. Therefore, it is crucial to maintain high sanitation standards throughout the entire cheese production process to ensure the safety and quality of the final product.

Intolerance to cheese
Cheese is a dairy product made from milk. Dairy products contain a sugar called lactose, which requires an enzyme called lactase to be broken down and digested. Lactose intolerance occurs when the body does not produce enough lactase to digest the lactose in food. This can be due to a variety of factors, including illness, injury, surgery, or genetics.
People with lactose intolerance can experience symptoms such as diarrhea, gas, bloating, abdominal pain, nausea, and vomiting after consuming dairy products, including cheese. The symptoms can start a few minutes to a few hours after consuming lactose and can last for an extended period. While lactose intolerance is typically not harmful, the symptoms can be uncomfortable.
It is important to note that not all cheeses are equally high in lactose. Hard cheeses, such as Cheddar, generally have lower lactose levels than soft cheeses. Additionally, aged cheeses tend to have lower lactose content than younger cheeses. Therefore, some individuals with lactose intolerance may find that they can tolerate certain types of cheese better than others.
If you suspect you have an intolerance to cheese, it is advisable to consult a doctor or a healthcare professional. They may recommend a lactose elimination diet, a hydrogen breath test, or a gastroscopy to confirm the diagnosis. Managing lactose intolerance typically involves reducing or eliminating lactose-containing foods from the diet or taking lactase supplements before consuming lactose.
In addition to lactose intolerance, it is worth mentioning that food poisoning is also a possible concern when consuming cheese. Raw or unpasteurized soft cheeses can contain harmful bacteria such as E. coli, Listeria, and Salmonella, which can cause vomiting and other gastrointestinal issues. However, food poisoning can also occur with pasteurized cheese due to contamination during processing or distribution.
