When hard cheese shows a mold spot, it is possible to carve away the affected area and continue consuming the rest. However, it is safer to discard foods with mold on them when the items are soft or have high moisture content. Foods such as soft cheeses, mozzarella, tomatoes, and yogurt should be treated with caution and disposed of if mold appears. This guidance comes from food safety experts, including indications discussed by Dr. Keith Schneider in sources from the University of Florida and daily news outlets.
Dr. Schneider notes that not every mold is dangerous, but some molds can release toxins that upset the stomach and trigger vomiting. In worst-case scenarios, certain toxins may contribute to more serious health issues. Consumers should be aware of the potential risks and treat mold growth in foods as a warning sign rather than a minor nuisance.
Soft and semi-soft cheeses contain higher moisture content, which supports mold growth, especially when refrigeration is not sufficiently cold. Mold toxins can spread through the liquid portion of a product, making it prudent to discard moldy soft cheeses such as mozzarella or blue cheeses like gorgonzola, as well as mold-affected bread. For harder cheeses like cheddar, it is acceptable to cut away the mold and an additional margin, typically around three centimeters, before using the remaining cheese.
Visible fuzzy or black spots on fruits and vegetables, particularly on tomatoes, can indicate black mold such as Stachybotrys chartarum. Exposure to this mold can lead to respiratory issues, allergic reactions, skin irritation, and in more severe cases, neurological symptoms or organ concerns. Caution and proper disposal are advised if such signs appear on produce.
In earlier discussions, some references described medical professionals or dietary guidance with varying degrees of emphasis on fried foods and related risks. Modern food safety emphasizes careful inspection, prompt disposal of moldy items, and maintaining clean, cold storage to minimize mold growth in the household kitchen.
