There is increasing evidence that Clostridium difficile is joining it's relatives Clostridium botulinum and Clostridium perfringens as a recognised foodborne pathogen.
Recent studies in the US, Europe and Canada have isolated this microbe from foods, including meat products for pet consumption.
However there has been no definite conclusions drawn about this being a foodborne pathogen at this stage. Further research is ongoing.
This bacteria is common in hospitals, aged care centres and respite, and in the US there are approximately three million cases in hospitals each year.
It causes diarrhoea and produces both spores and a toxin.
