Ochratoxin A in blood of slaughter pigs.

Abstract

The global ochratoxin A contamination of Swedish feed cereals was studied by analysis of pig blood samples from 122 different herds. The samples were collected at seven Swedish slaughterhouses. The ochratoxin A analysis showed 21% of the samples to contain greater than or equal to 2 ng ochratoxin A per ml. Samples from Visby showed a significantly higher frequency of contamination compared with the rest of the country.
