Cheese is made from cow's milk, which contains pus from cows with bacterial infections
Cheese is a beloved food for many, but its production and consumption have been the subject of much debate, especially regarding animal welfare and health concerns. One of the most disturbing claims is that cheese is made from cow's milk, which contains pus from cows with bacterial infections. This belief has sparked disgust and controversy among consumers, leading to a closer examination of the dairy industry and its impact on both animal well-being and human health.
Firstly, it is important to understand that cheese is primarily made from milk, and the quality and safety of the milk play a crucial role in the final product. While it is true that cheese is derived from cow's milk, the presence of pus in the milk due to bacterial infections is a complex issue that warrants further explanation.
The discussion of pus in cow's milk revolves around the concept of somatic cells. Somatic cells are naturally present in milk, including human breast milk, and they consist mostly of non-inflammatory white blood cells and epithelial cells shed from the mammary gland ducts. However, when a cow's udder becomes infected, the number of inflammatory immune cells, known as neutrophils, increases significantly. These neutrophils are the primary component of pus, leading to the concern about pus in milk.
The dairy industry has been criticized for the high prevalence of mastitis, an udder infection, in dairy cows. This epidemic is a direct result of the intensive milk production practices employed by the industry. Cows endure constant cycles of artificial insemination, pregnancy, and mechanized milking, taking a toll on their health. As a result, many cows develop infections, and the milk they produce may contain elevated levels of somatic cells, including neutrophils, which can be considered pus. While there are regulations in place to limit the amount of pus allowed in milk, it is still a disturbing reality for consumers.
The presence of pus in cheese highlights the broader issues within the dairy industry, including animal cruelty and the potential health risks associated with consuming dairy products. The intensive milk production methods not only lead to a high rate of infections in cows but also contribute to shortened lifespans and inhumane treatment. As a result, many people are re-evaluating their consumption of dairy products, including cheese, and exploring alternative options like vegan cheese, which offer similar flavors without the ethical and health concerns associated with traditional cheese.

The antiseptics used to disinfect cow teats can increase pus levels in milk from cows with staph-infected udders
Dairy cows are subjected to annual cycles of artificial insemination, pregnancy, birth, and mechanized milking for 10 out of 12 months, including 7 months of their 9-month pregnancies. This excessive metabolic drain overburdens the cows, reducing their productivity and profitability over time. As a result, they are often treated as mere milk machines, leading to various production-related diseases, with lameness and mastitis (udder infections) being the top causes of dairy cow mortality in the United States.
Mastitis, an inflammation of the udder, is a common issue in dairy cows, with 1 in 6 dairy cows in the United States suffering from clinical mastitis, which is also responsible for a significant number of dairy cow deaths. The condition is caused by bacterial infections, particularly Streptococcus agalactiae, Staph. aureus, and Str. dysgalactiae. These pathogens can colonize teat sores and lesions on teat ducts, or cows may be exposed through contaminated bedding, corrals, or equipment.
To prevent and treat mastitis, teat disinfection and antibiotic therapy are commonly employed. While teat dipping or spraying with disinfectants can effectively reduce exposure to pathogens, the antiseptics used can boost pus levels in milk from cows with staph-infected udders. This occurs due to the iodine in the antiseptics, which can increase pus formation.
The presence of pus in milk, or more specifically, the high somatic cell count, can impact the quality of dairy products. A study published in the Journal of Dairy Science found that cheese made from milk with a high somatic cell count had defects in texture and flavor, as well as increased clotting time compared to milk adhering to stricter European standards. While the U.S. dairy industry asserts that pasteurization eliminates any safety concerns, consumers may still find the idea of consuming pasteurized pus unappealing.
The issue of pus in milk highlights the ethical concerns surrounding the treatment of dairy cows. The intensive production cycles and mechanized milking practices in the dairy industry contribute to the high prevalence of mastitis and other health issues in dairy cows. As consumers and advocates for animal welfare, it is important to recognize the impact of these practices and consider alternatives, such as vegan cheese options, that can spare cows from suffering and provide healthier choices.

The US has laws limiting the amount of pus allowed in milk
The US has laws that limit the amount of pus allowed in milk. These laws are in place to ensure that milk is safe for human consumption and to reduce the risk of foodborne illnesses. While the presence of pus in milk may sound unappetizing, it is important to understand the context and the science behind it.
Firstly, it is important to clarify that the term "pus cell" is misleading. While milk from cows can contain white blood cells, these are not the same as pus cells. White blood cells, also known as leukocytes, are a natural component of milk in healthy cows, just as they are in human breast milk. These cells play a crucial role in fighting infections and maintaining the health of the cow.
However, when cows are subjected to intensive farming practices, they can develop infections, such as mastitis, which is an inflammation of the udder. This condition can lead to an increased presence of white blood cells in the milk, which some may refer to as "pus". It is important to note that farmers have a strong financial incentive to keep their cows healthy and free from infection, as milk that fails to meet regulatory standards can result in significant penalties.
In the United States, the allowable limit of somatic cells, which include white blood cells, in milk is set at 750,000 cells per milliliter. This limit is higher than that of Europe, which allows up to 400,000 cells per milliliter. It is worth noting that the majority of milk produced in the US falls below this limit, with approximately 95% of milk having fewer than 400,000 cells per milliliter.
While the presence of white blood cells in milk may be unappealing to some, it is important to understand that pasteurization kills any harmful bacteria that may be present. Additionally, the dairy industry argues that pus itself is not inherently harmful and is a natural part of an animal's defense system. However, it is worth considering the impact of intensive farming practices on the health and well-being of dairy cows, as well as the potential impact on the taste and quality of the milk produced.

The average somatic cell count in US milk is 1,120,000 per spoonful, or a million pus cells per spoonful
The presence of pus in milk is a result of the mastitis epidemic in the US dairy herd. Mastitis is an infection of the udder, and it is one of the leading causes of dairy cow mortality in the United States. The infection causes an increase in the number of somatic cells in the milk. While somatic cells are not synonymous with pus cells, they can be a source of pus if the udder is infected.
Somatic cell count (SCC) is an indicator of milk quality, specifically, its low likelihood to contain harmful bacteria, and thus its high food safety. SCC is quantified as the number of somatic cells per ml of milk. A cow with an SCC of 100,000 or less is considered 'uninfected', while a threshold of 200,000 or more indicates that the cow is likely infected with mastitis. In Canada, the European Union, Australia, New Zealand, Switzerland, and some US states, the somatic cell count shall be no more than 400,000 cells per milliliter. However, in most US states, the limit is 750,000, and in Brazil, it is 1,000,000.
The average somatic cell count in US milk is 1,120,000 per spoonful, which is equivalent to a million pus cells per spoonful. While this sounds like a lot, pus is highly concentrated, so this amount of somatic cells would translate to only a single drop of pus per cup of milk. According to the dairy industry, pus is a natural part of an animal's defense system and is not harmful to humans.
It is important to note that the presence of pus in milk is not just a result of infections but also the use of antiseptics to disinfect cow teats, which can boost the level of pus in the milk of cows with staph-infected udders. The excessive metabolic drain caused by annual cycles of artificial insemination, pregnancy, birth, and mechanized milking can also contribute to the high rate of production-related diseases in dairy cows.

The dairy industry separates calves from their mothers to harvest milk meant for the calves
The dairy industry has long been the subject of criticism for its treatment of cows and calves. One of the most emotive issues is the separation of calves from their mothers, a practice that allows farmers to sell the milk meant for the calves. Typically, calves are separated from their mothers within hours or days of birth, with only 4% of farmers keeping calves with their mothers for more than 24 hours.
This separation is distressing for both the calves and their mothers. In nature, cows would live together as a family with their grandchildren and great-grandchildren, so the early separation interferes with this natural family process. Calves that are reared by their mothers display more natural behaviours, improved social behaviour, and better health, with lower mortality rates. They also gain more weight, as they are able to drink their mother's milk more frequently.
Keeping calves with their mothers also has health benefits for the cows. The suckling can help protect them against mastitis, one of the biggest disease risks in dairy farming. Mastitis is an udder infection that can cause pus in milk. The antiseptics used to disinfect cow teats can also boost the level of pus in the milk of cows with staph-infected udders.
Some farmers are now allowing calves to stay with their mothers for longer, but this is a controversial topic in the industry. While some believe that the health and welfare benefits for the cows and calves are worth the loss of milk, others remain sceptical, citing potential increases in disease risk and the difficulty of controlling the calf's food intake.

Frequently asked questions
Cheese is made from milk. Therefore, if there is pus in milk, there is pus in cheese. However, there is conflicting information on whether or not pus is present in milk. Some sources claim that there is pus in milk due to the high somatic cell count, which reflects the levels of infection and inflammation in the mammary glands of dairy cows. Others claim that there is no pus in milk, and that the term “pus cells” is misleading, as pus is made up of various components and is not a single type of cell.
Pus is made up of dead white blood cells, dead skin cells, and bacteria.
The amount of pus in milk can vary depending on the level of infection and inflammation in the cow's mammary glands. Some sources claim that there can be up to a million pus cells per spoonful of milk, while others estimate a single pus-drop per cup.
The presence of pus in milk is generally considered undesirable and may indicate a high level of infection or inflammation in the cow's mammary glands. While it may not be directly harmful to humans in small amounts, it can be a sign of poor animal welfare and unsanitary conditions.
According to some sources, there is no difference in the presence of pus between organic and conventional milk. However, it is important to note that milk is generally subject to regulations and safety standards, and farmers have incentives to keep their cows healthy and free from infection.
