Bacillus cereus bacteria, coloured scanning electron micrograph (SEM). B. cereus is a Gram positive, spore forming bacteria found in soil. It produces two toxins that cause foodborne illnesses. One causes diarrhoea 8 to 16 hours after ingestion, the other vomiting and nausea between 1 and 5 hours after ingestion. The latter toxin is particularly prevalent on rice that has been cooked and then improperly refrigerated. The bacterial spores survive and germinate, leading to illness after consumption. Magnification: x41,600 when printed at 10 centimetres wide.
