This study was undertaken to evaluate two monoclonal antibody‐based sandwich ELISAs (sELISAs) for the detection of Clostridium botulinum neurotoxins (BoNTs) types C and D from culture‐enriched intestinal content samples from cattle. To validate the diagnostic significance of the presence of cultivable, toxin‐producing C botulinum in the intestines of cattle, samples from both suspect and non‐suspect botulism cases were examined. BoNT was detected by both sELISAs in a greater number of suspect animals than by direct testing of uncultured samples by mouse bioassay. One sELISA detected two BoNT C and one BoNT Group III mosaic isoform in three animals that were missed by the other, and both sELISAs failed to identify samples from two mouse bioassay‐positive BoNT C animals. BoNT D was also detected in one non‐suspect sample by one of the sELISAs.
