The aim of present study was to reveal the toxicokinetic properties and absolute oral bioavailability of enniatin B1 in pigs. Five pigs were administered this Fusarium mycotoxin per os and intravenously in a two-way cross-over design. The toxicokinetic profile fitted a two-compartmental model. Enniatin B1 is rapidly absorbed after oral administration (T(1/2a)=0.15 h, Tmax=0.24h) and rapidly distributed and eliminated as well (T(1/2elα)=0.15 h; T(1/2elβ)=1.57 h). The absolute oral bioavailability is high (90.9%), indicating a clear systemic exposure. After intravenous administration, the mycotoxin is distributed and eliminated rapidly (T(1/2elα)=0.15 h; T(1/2elβ)=1.13 h), in accordance with oral administration.
