RETRACTED: Antioxidant nutrients and mycotoxins (Retracted Article)

Mycotoxins are fungal secondary metabolites that are toxic to vertebrates produced by organisms that occur as plant pathogens wide and may be recovered,ens, soilborne fungi, airborne fungi and aeroallergens. They are distributed world from a wide range of substrates. Their presence in food and feeds, as the result of fungal diseases in crops, can present a danger to animal and human health. Many mycotoxins have also been shown to be phytotoxic and in some cases, such as with trichothecenes produced by the wheat head blight fungus Fusarium graminearian, mycotoxins may act as virulence factors. Several natural (vitamin, provitamins, carotenoids, chlorophyll and its derivatives, phenolics. and selenium) and synthetic (butylated hydroxyanisole and butylated hydroxytoluene) compounds with antioxidant properties seem to be potentially very efficacious in protecting against the toxic effects of mycotoxins. The protective properties of antioxidants are probably due to their ability to act as superoxide anion scavengers, thereby protecting cell membranes from mycotoxin-induced damage and in some cases, antioxidant vitamins may play a role in preventing mycotoxicosis. However, much less information is available from studies carried out on antioxidants and mycotoxins, such as OTA, FB1, T-2 toxin, ZEN, and citrinin. No such studies have been performed on recently discovered toxins such as beauvericin, fusaproliferin, moniliformin, and fusaric acid. However, supplementation with antioxidant nutrients to prevent mycotoxicosis has been controversial. The case for the use of supplemental antioxidant vitamins at the present time needs further research. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
