A procedure is presented for screening the quality of feed in respect to ochratoxin A contamination based upon the analysis of ochratoxin A in pig blood. Representative samples from large feed lots may be obtained by using pigs as in vivo sample collectors which enrich the toxin and forms homogeneous samples in the blood. The spectrofluorometric procedure for ochratoxin A analysis (K. Hult and S. Gatenbeck, J. Assoc. Off. Anal. Chem. 59:128-129, 1976) has been adapted to pig blood and has been simplified to involve only three extraction steps. A volume of 2.5 ml of blood or plasma is needed, and the detection limit is 2 ng of ochratoxin A per ml. The disappearance of ochratoxin A from pig blood as a function of time has been studied. A feeding experiment with ochratoxin A has been performed, and the time course of the concentration of ochratoxin A in blood has been followed during the experiment.
