How is blue cheese related to microbes?

A related fungus, Penicillium roqueforti, is the key microbe in blue cheese (Figure 1B).

Does blue cheese have penicillin in it?

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’s also worth noting that only 20 per cent of people who think they are allergic to penicillin, actually are.
