Despite a common misconception, the mold used to produce blue cheese is not the same strain used to make the antibiotic penicillin. This means that blue cheese dressing does not contain the antibiotic penicillin, though the cheese itself is made with a different, food-safe mold. The confusion arises from both substances belonging to the same genus of fungi, *Penicillium*.

The creamy edible rind of brie cheese is created by the mold *Penicillium camemberti*, which belongs to the same genus as the mold that produces the famous antibiotic. This shared name has led many to question: **Is brie cheese an antibiotic?** The definitive answer is no, and understanding the science behind this distinction is key to informed nutrition.

Over 350 species of Penicillium exist, with some being essential for gourmet cheese production, while others produce dangerous toxins. Understanding which type of mold is in your food is critical, as the answer to 'Is Penicillium safe to consume?' is not a simple yes or no.

Up to 80% of individuals who believe they have a penicillin allergy are not actually allergic, and among those who are, many mistakenly avoid mold-ripened cheeses. Understanding what cheese to avoid if allergic to penicillin is crucial for enjoying a diverse diet without unnecessary fear, but it requires distinguishing between the antibiotic and the molds used in cheese production.
