Abstract:
1. A process for determining the presence or absence of an antimicrobial residue in a sample, which process comprises: (i) contacting the sample with a test suitable for determining the presence or absence of an antimicrobial residue in the sample; (ii) inactivating any natural disturbing compound present in the sample which is capable of inhibiting the test and which leads to a false positive result absent said inactivating step, by heating said contacted sample and test to a temperature of 75° C. to 85° C. for a sufficient time interval to inactivate the natural disturbing compound that may be present in the sample; followed by (iii) incubating the contacted sample and test to determine whether microbial growth occurs, whereby the absence of microbial growth indicates the presence of at least one antimicrobial residue.
