INTRODUCTIONABSTRACTMost fungi are able to produce several mycotoxins simultaneously; moreover food and feed canbe contaminated by several fungi species at the same time. Thus, humans and animals are generallynot exposed to one mycotoxin but to several toxins at the same time. Most of the studies concerningthe toxicological effect of mycotoxins have been carried out taking into account only one mycotoxin.In the present review, we analyzed 112 reports where laboratory or farm animals were exposedto a combination of mycotoxins, and we determined for each parameter measured the type ofinteraction that was observed. Most of the published papers concern interactions with aflatoxins andother mycotoxins, especially fumonisins, ochratoxin A and trichothecenes. A few papers alsoinvestigated the interaction between ochratoxin A and citrinin, or between different toxins fromFusarium species. Only, experiments with a 2 x 2 factorial design with individual and combinedeffects of the mycotoxins were selected. Based on the raw published data, we classified theinteractions in four different categories: synergistic, additive, less than additive or antagonisticeffects.This review highlights the complexity of mycotoxins interactions which varies according to theanimal species, the dose of toxins, the length of exposure but also the parameters measured.Keywords : co-contamination, toxicological synergism, animal health, feeding trials, chronic toxicity.21
