Abstract:

The occurrence of ochratoxin A in pig blood can be used as a measure of ochratoxin A contamination of the feed. A method for ochratoxin A analysis in pig blood, suitable for screening programs, is presented. The relationship between ochratoxin A contents in the blood of pigs and the feed given is investigated with feeding experiments. Blood samples from pigs originating from 279 herds slaughtered in nine slaughter-houses in Sweden were analyzed for ochratoxin A. In total, 14% of the investigated pigs contained greater than or equal to 2 ng ochratoxin A per ml blood. The highest level found was 215 ng/mL. Correlations between the occurrence of ochratoxin A in the blood and parameters concerning the feed are investigated.

Toxicity Testing in Animals

Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
