hi the antibiotic penicillin is made from the fungus penicillium chrysogenum. stilton and most other blue cheeses do use penicillium mould to create the blue veins but they use a different strain ( p. roqueforti ) and the whole mould rather than the penicillin extract. it is possible to be allergic to the drug and still be able to eat the cheese with impunity although there are also people who are allergic to both. it’s also worth noting that only 20 per cent of people who think they are allergic to penicillin actually are. do hope this helps you. good luck
is it safe to eat blue cheese if you are alergic to penicillin. i am seriously alergic to penicillin. is blue cheese or chips and pretzels made with blue cheese as one of their ingredience something i should stay away from?
