Mutagenit tspr fung industriell verwendeterP. camemberti- undP. roqueforti-St mme

Abstract
Summary We tested the mutagenic potential of crude extracts of 18 strains ofPenicillium camemberti- and 6 strains ofP. roqueforti, which are used commercially in the production of mould ripened cheese in Switzerland. No mutagenic activity could be detected in any of the extracts. Roquefortine, a mycotoxin ofP. roqueforti, often found in Blue cheese, was negative in the Amestest. The results obtained do not lead reasons for experting undesired long term effects from the consumption of mould ripened cheese.
