Content of ochratoxin A in paired kidney and meat samples from healthy Danish slaughter pigs
2002
Jørgensen, K. | Petersen, A.
In 1999, paired samples of kidney and meat were taken from 300 healthy Danish pigs and analysed for ochratoxin A. The concentrations of ochratoxin A in kidney ranged from 0 to 15 micrograms kg-1 (mean 0.50 micrograms kg-1, median 0.18 micrograms kg-1) and in meat from 0 to 2.9 micrograms kg-1 (mean 0.12 micrograms kg-1, median 0.03 micrograms kg-1). The data together with the Danish control data show that today the pig industry in Denmark has no problem keeping the content of ochratoxin A in pig at very low levels even in years with wet harvest conditions. The mean ratio 'content in meat/content in kidney' for paired samples was 39%. For kidney samples >1.0 micrograms kg-1, the mean ratio was 22%. The Danish control system for ochratoxin A in pig kidney established in 1978 can be regarded as a success because the levels in pig have been reduced substantially, and hence for the consumer the contribution from pig products to the total intake of ochratoxin A is very small compared with other sources.
