Patulin is a mycotoxin produced by a variety of molds, in particular, Aspergillus and Penicillium. It is commonly found in rotting apples, and the amount of patulin in apple products is generally viewed as a measure of the quality of the apples used in production. It is not a particularly potent toxin, but a number of studies have shown that it is genotoxic, which has led to some theories that claim that it may be a carcinogen, though animal studies have remained inconclusive.[2] Patulin is also an antibiotic.[1] Several countries have instituted patulin restrictions in apple products. The World Health Organization recommends a maximum concentration of 50 µg/L in apple juice.[3]

In European Union, the limit is set to 50 micrograms per kilogram (µg/kg) in both apple juice and cider, and to half of that concentration, 25 µg/kg in solid apple products and 10 µg/kg in products for infants and young children. These limits came into force on 1 November 2003. [4]
