T-2 and HT-2 in bright coloured and dark oats T2 toxin - 87 µg/kg, HT-2 toxin 290 µg/kg T2 toxin - <10 µg/kg, HT-2 toxin 22 µg/kg Tests accredited under the German DAR accreditation scheme which complies to ISO 17025 1

Assessment of maximum quantity p-tdi: 0,06 µg T-2 and HT-2/kg body weight (safety factor 500, due to less data available and low difference between LOAEL and NOAEL) (SCF, 30 May 2001) maximum quantity p TDI body weight in food µg/kg: daily consumption maximum quantity: (at-risk group: child, high consumer) 0,06µg / kg bw 16,15 0,0643kg kg = 15 µg / kg with current data estimated maximum quantity is not feasible!!! 5
Further steps Toxicology - Assessment of the toxicology study in general - Assessment of the availability of T2 /HT2 from oats - Assessment of the safety factor of 500 Establishment and validation of an analytical method Collection of further data Development of guidelines for growers and processors 6
Conclusions As an industry we have an extensive programme of ongoing work which is being undertaken across Europe and more time is needed to obtain, assess and analyse the data Climate is one of the main influencing factors which leads to great variation in disease incidence and resultant Mycotoxin levels BUT it is not necessarily what you would expect 7
Conclusions We need time to understand the interactions between different Mycotoxins and the influences on them and until more work has been undertaken, which we as an industry are already actively pursuing, the management of this will remain difficult 8
