The Bacillus cereus group frequently contaminates milk and dairy products. Some members of this group can produce the heat-stable pre-formed toxin cereulide, which causes emetic foodborne intoxication. This study characterised emetic B. cereus group isolates from raw cow’s milk in the biochemical, g...
