  Abstract: The Botulinum Toxin ELISA effectively provided presumptive identification of toxin in 1381 investigation samples including clinical specimens, suspect foods, and cultures. Additionally, the ELISA detected all toxins produced by a panel of stock strains representing known subtypes and was negative for non-botulinum toxin producing Clostridium and enteric pathogens. ELISA results were reproducible both within the same kit (CV < 9%) and among different production lots (CV < 23%). Fifty-five of 57 laboratories correctly identified unknown samples in a multi-laboratory study. The ELISA provides a rapid, robust in vitro screening method which will reduce animal dependence during laboratory investigations of botulism.
