Food And Feed Safety

Mycotoxins are a group of naturally occurring toxins that are produced by different filamentous fungi genera such as Aspergillus, Penicillium, Fusarium, etc. The word mycotoxin literally is derived from Greek word “myke” meaning fungus and “toxicum” meaning toxin. These contaminants can develop on different food and feed commodities during different stages including pre-harvest, harvest, and storage. Mycotoxins are of concern because their outbreak result in animal and human diseases and economic losses. It has been estimated that global post-harvest losses are approximately at 50%. Human exposure to mycotoxins is typically through consumption of contaminated agricultural products or indirectly by consumption of animal products containing mycotoxins or their metabolites. The chapter provides the latest information on mycotoxin issues and challenges related to food and feed safety.

Worldwide recognition that aflatoxin contamination of agricultural commodities by the fungus Aspergillus flavus is a global problem has significantly benefitted from global collaboration for understanding the contaminating fungus, as well as for developing and implementing solutions against the contamination. The effort to address this serious food and feed safety issue has led to a detailed understanding of the taxonomy, ecology, physiology, genomics and evolution of A. flavus, as well as strategies to reduce or control pre-harvest aflatoxin contamination, including (1) biological control, using atoxigenic aspergilli, (2) proteomic and genomic analyses for identifying resistance factors in maize as potential breeding markers to enable development of resistant maize lines, and (3) enhancing host-resistance by bioengineering of susceptible crops, such as cotton, maize, peanut and tree nuts. A post-harvest measure to prevent the occurrence of aflatoxin contamination in storage is also an important component for reducing exposure of populations worldwide to aflatoxins in food and feed supplies. The effect of environmental changes on aflatoxin contamination levels has recently become an important aspect for study to anticipate future contamination levels. The ability of A. flavus to produce dozens of secondary metabolites, in addition to aflatoxins, has created a new avenue of research for understanding the role these metabolites play in the survival and biodiversity of this fungus. The understanding of A. flavus, the aflatoxin contamination problem, and control measures to prevent the contamination has become a unique example for an integrated approach to safeguard global food and feed safety.

Food And Feed Safety

Abstract This paper evaluates the potential hazards of food and feed derived from RNAi plants including: adverse changes of plant metabolism; mechanisms and potential for non-target gene silencing in humans and livestock, including gut microbiome; bioinformatics tools for predictionof off-target sequences of interfering RNA; the possible non-specific effects of dsRNA and siRNA in mammals; and the comparison of data requirements for safety assessment of food and feed from RNAi plants and from plants expressing recombinant proteins. It also discusses exposure and RNAi-specific risk assessment.
