The 2nd U.S Circuit of Appeals in New York, US reinstated a lawsuit filed by the Natural Resources Defence Council against the US Food and Drug Administration (FDA). The court concluded that triclosan was potentially dangerous and that the US FDA had allowed the substance to enter the market without previous safety confirmation. Triclosan is considered to increase the risks of ovarian cancer and to have hormone-disrupting effects. Apart from being used in soaps and detergents, it is authorized in Europe for plastic materials and articles intended to come into contact with foodstuffs (EC 10/2011, Annex I) and is used as an antimicrobial in active packaging (Camilloto et al. 2009, Quintavalla et al. 2002).
