Although species of Fusarium were pervasive in commercial corn (Kommedahl and Windels, 1981) and many species of Fusarium were known mycotoxin producers (Joffe, 1965), the adverse effects of T-2 toxin (a Fusarium mycotoxin) in poultry were not described under laboratory conditions until the early 1970s (Wyatt et al. 1973, 1975). Since these early descriptions, other laboratory studies have documented the effects of a number of other Fusarium mycotoxins on poultry (Hoerr et al., 1981; Mirocha, 1983; Chu et al., 1988; Walser et al., 1988; Ademoyero and Hamilton, 1989; Marijanovic et al., 1991; Wu et al., 1991). While valuable for their basic physiological and toxicological information, these laboratory studies have been of limited value in the diagnosis of field outbreaks of fusarotoxicosis since the simultaneous occurrence of Fusarium mycotoxins (Ciegler, 1978) and “mycotoxin hot spots” (Shotwell et al., 1975) often produced vague, confusing, or conflicting symptoms. These confusing symptoms along with the need for prompt answers in commercial animal production situations and a lack of suitable field analytical methods for the detection of Fusarium mycotoxins have hampered efforts to study fusarotoxicosis under field conditions. Furthermore, it is clear that the study of field fusarotoxicosis incidents is beset with a set of obstacles entirely different from those encountered in laboratory studies. Thus, techniques or procedures which work well in laboratory situations may be entirely inappropriate in field situations.
