Table 1. Recommended mycotoxin
risk thresholds for poultry

(DON) and other trichothecene toxins as well as zearalenone (ZEN). The same fungi can cause ear rot in
corn, as can the fumonisin (FUM)-producing F. verticillioides.  These three mycotoxins have presented the
greatest risk to poultry during the past 10 years.
➤Sometimes, mycotoxin levels can increase in
corn and cereals in one season but quite often
the trends are different (Figure 1). A risk assessment
based on the proportion of raw commodity and finished feed samples for which at least one mycotoxin
was above the risk threshold (Table 1) reveals an obvious fluctuation from year to year.
➤The risk for finished feed often tracks the pattern of corn for six monthly fluctuations in each
of the four continents represented in Figure 1. This
is to be expected, given corn's prominence in poultry
