Description: This collection of papers represents some of those given at the International Congress for Plant Pathology held in Turin in 2008 in the session with the title “The Role of Plant Pathology in Food Safety and Food Security”. Although food safety in terms of “Is this food safe to eat?” did not receive much direct attention it is, nevertheless, an important topic. A crop may not be safe to eat because of its inher- ent qualities. Cassava, for example, is cyanogenic, and must be carefully prepared if toxicosis is to be avoided. Other crops may be safe to eat providing they are not infected or infested by microorganisms. Mycotoxins are notorious examples of compounds which may contaminate a crop either pre- or post-harvest owing to the growth of fungi. Two papers in this book deal with toxins, one by Barbara Howlett and co-workers and the other by Robert Proctor and co-workers. In the first of these, the role of sirodesmin PL, a compound produced by Leptosphaeria macu- lans, causal agent of blackleg disease of oilseed rape (Brassica napus), is discussed. The authors conclude that the toxin plays a role in virulence of the fungus and may also be beneficial in protecting the pathogen from other competing micro-organisms but there seem to be no reports of its mammalian toxicity. In the second paper, attention is drawn to the many plant diseases caused by the fungus, Fusarium pro- liferatum, and the fact that it produces a wide range of biologically active metabo- lites, including the fumonisins. These compounds, in a related fungus, Gibberella fujikuroi, play a role in virulence but have also been identified as carcinogens.
