The dangers of mouldy food for poultry
While blue cheese is not directly toxic to poultry, mouldy food can pose several dangers to their health. Firstly, mould on food can produce a toxic component that leads to a life-threatening condition known as Mycotoxicosis, which can poison chickens similarly to pesticides. Consuming mouldy food can cause digestive distress and even death in poultry.
Blue cheese, in particular, is manufactured from mould cultures, specifically Penicillium roqueforti and Penicillium glaucum, which give it its distinctive blue or green veins. While these moulds are generally safe for human consumption and have antibacterial properties, they can still be harmful to poultry.
The high fat and salt content of blue cheese can also be detrimental to poultry. Cheese is high in saturated fat, which can lead to obesity and other health issues in birds if consumed in excess. Salt, which is usually added to cheese for taste, can also be harmful to birds if consumed in large quantities. Therefore, it is essential to limit the quantity of cheese in a bird's diet and avoid highly processed or salty varieties.
Furthermore, while poultry can handle small amounts of dairy, they cannot digest large amounts. Consuming too much dairy can lead to lactose malabsorption, causing uncomfortable symptoms. Therefore, it is recommended to provide fresh milk, yoghurt, whey, and cottage cheese in moderation, being cautious of mouldy cheese.
In conclusion, while blue cheese may not be directly toxic to poultry, mouldy food, in general, can pose serious health risks. It is crucial to prioritise the health of your poultry and avoid feeding them mouldy or expired food, including blue cheese.

Blue cheese's high salt content
Blue cheese is manufactured from mould cultures, specifically Penicillium roqueforti and Penicillium glaucum, which are safe for human consumption. These moulds are antibacterial and limit the growth of pathogens on the cheese. While blue cheese is not directly toxic to poultry, it is a salty food. A high salt content in a chicken's diet can cause health issues. Therefore, it is recommended to limit the quantity of blue cheese fed to poultry.
Salt is added to cheese during the curing process, and while it is not harmful to humans, it can be dangerous for chickens. A chicken's diet should consist of no more than 10% cheese, as the high-fat content can lead to obesity and other health issues. Furthermore, while chickens are not lactose intolerant, large amounts of milk in their diet can make them sick.
The mould in blue cheese is often cited as a concern for poultry owners. While mould on its own is toxic and can make birds extremely sick, the mould in blue cheese is not dangerous. This is because the conditions in which the moulds grow—acidity, salinity, moisture, density, temperature, and oxygen flow—are not conducive to the growth of toxic moulds.
However, some people still advise against feeding blue cheese to poultry due to the potential risks of mouldy food. It is recommended to avoid giving mouldy food of any kind to poultry, as it can cause health issues. Some sources suggest that blue cheese with mycotoxins can suppress immune functions, cause cancer, digestive distress, and even death in poultry. Therefore, while the controlled mould in blue cheese is safe, it is still important to exercise caution and not feed mouldy blue cheese to poultry.
In conclusion, while blue cheese may have health benefits for poultry due to its nutritional content, it is important to monitor the amount fed to birds due to its high salt and fat content. Additionally, while the mould in blue cheese is generally safe, it is best to avoid feeding mouldy blue cheese to poultry to prevent potential health risks.

Blue cheese's antibacterial properties
Blue cheese is made from mould cultures of the genus Penicillium, specifically Penicillium roqueforti and Penicillium glaucum. These moulds are responsible for the distinctive blue or green veins that characterise blue cheese. While blue cheese is safe for human consumption, opinions vary on whether it is safe to feed blue cheese to poultry.
Some sources advise against feeding blue cheese to poultry due to its high salt content and the potential presence of mould. Mouldy foods can cause several health issues in poultry, including immune suppression, digestive distress, and even death. However, the moulds used in blue cheese production are safe and recognised as healthy for human consumption due to their antibacterial properties.
The moulds Penicillium roqueforti and Penicillium glaucum have antibacterial properties that can limit the growth of pathogens. These moulds produce compounds with antifungal, antibacterial, and other biological properties. Virginia Tech researchers have discovered a way to synthesise these compounds on a large scale, which has potential for new antibacterial applications. Additionally, the production of roquefortine L, a compound central to the creation of other molecules, exhibits broad antimicrobial properties and promising anticancer effects.
While blue cheese contains penicillin-producing moulds, it is unlikely to possess significant antibiotic properties. The strains of Penicillium used in cheesemaking differ from those used in penicillin production, and factors such as enzymes and pH changes during the cheesemaking process can degrade any penicillin present. Therefore, while blue cheese may have some antibacterial properties, it is not a significant source of antibiotics.
