Fifty‐nine samples of can‐cooling water from 30 midwestern canneries were examined for aerobic plate count, salmonellae, coagulase‐positive staphylococci, coliforms, enterococci, and mesophilic aerobic and anaerobic (putrefactive) spores including spores of Clostridium botulinum . No Salmonella or C. botulinum were detected. Indicator bacteria counts were low with nearly 75% of the samples showing MPN levels of >0.03/ml. One sample contained a low level (0.1/ml) of enterotoxigenie Staphylococcus aureus . This particular sample had no detectable germicide residual. Spore counts were low. Aerobic plate counts ranged from >1 to 210,000/ml.
