Title: Food security and food safety can secure together the survival of mankind

Abstract

Food security was very much stressed, but much less the food safety caused by toxigenic fungi. Toxin contaminated grains has much less or no value. We need the beside the amount of food and feed that they are non toxic. Economic lossed In goes for billions in dollars, in Hungary the 2014 maize sufferd about 300 million USD. The research clarified in maize an wheat that the most important toxin regulating agent is the resistance in both plants. In wheat the resistance to different Fusarium spp. is common, so testing F. graminearum resistance is enough. But this is  in maize mostly independent, they need independent tests. The tested pathogens in maize: F. graminearum, F. verticillioides and Aspergillus flavus. More than ten time differences in resistance in commercial cultivars and hybrids were found. About 10-15 % of the hybrids shows good resistance to all species, most are very differring. Besides resistance the measurement of toxins is inevitable. This makes possible to screen wheat and maize for resistance ti toxigenic fungi. As a result susceptible and very susceptible genotypes should not be registered or should be withdrawn fom production. We did not find yield penalty for highly resistant varieties. So their combination with a consequent breeding work is without compromises possible. The breeding phylosophy therefore needs to be updated to correspond to the new challanges both for human food and animal feed safety. I think the the yield maximalization without food safety should be over.
