Increased occurrence of mycotoxins in various food and feed commodities continues to impact negatively on animal and human health and the economy. This is typical in the case of Africa, where environmental conditions for the proliferation of mycotoxigenic fungi exists. Therefore, exposure to mycotoxins in this part of the world is alarming and cases of mycotoxin poisoning with lethal consequences among humans and animals resulting from exposure to them at extremely high levels have been reported (particularly in Kenya and South Africa) driving the need for effective and proper routine analysis of food and feeds and to estimate exposure levels among humans and animals of these naturally occurring toxicants. With this in mind, the Pegasus-HRT 4D gas chromatography time-of-flight mass spectrometry (Pegasus-HRT 4D GC�?GC-TOF-MS) can provide adequate analysis of mycotoxins and their biotransformation products in foods, feeds and other biological materials where applicable. Its exceptional speed (200 spectra/sec), accurate molecular mass determination, full mass range acquisition, ultra-high resolution (50, 000 FWHM) and low detection limits positions makes it as an effective tool for mycotoxin analysis in food and feeds. Its rich analytical capacity and high confidence-analyte identification also makes it a viable option for exposure studies and identification of mycotoxin metabolites. This presentation will provide up-to-date data on mycotoxin contamination of food and feeds as well as the degree with which humans and animals are exposed to them in Africa. It also provides some detailed information on the applicability of Pegasus-HRT in assessing exposure.
