Summary The distribution of bacteria, including Bacillus cereus and mesophilic sporeformers surviving 100 o C. for 2 minutes, was determined by swabbing different parts of milk cans from 2 dairies having a good record. In all, 288 cans were examined over a 12‐month period; 36 cans from a further 2 dairies were examined during July and August. Lid surfaces and the rim of the can yielded relatively high numbers of bacteria, compared with other parts; together they often yielded more than the whole of the rest of the can. There was no marked seasonal variation in the numbers except with B. cereus spores, which were found in larger numbers in the period July–October. It is concluded that while a rinse method will give useful information on the relatively efficiency of can cleansing, it does not give a complete picture of the can as a source of contamination.
