Moreover, in any scientific attempt to establish a safe level of a mycotoxin it seems
essential to define safety and criteria to be used in its establishment. It is very difficult to set up valid and accepted levels of performance in animal production on a worldwide
basis, and it is even more difficult to produce numbers and correlations that refer
directly to the impact of hazards. Should safe levels refer to lethal effects, growth depression,
and pathological findings, or rather to the grade of immunological changes, deviations
of enzymatic parameters or haematological factors? What is the proper criterion for
“safety”
