Bacilli cause symptoms leading to illness, relatively mild lasting up to 24h, but could be severe leading to hospitalisation and in some cases death. The organism is found in a wide range of habitat including air, water, dust and soil, from where spores are introduced into cereal crops, vegetables, animal hair, fresh water and sediments. Raw plant foods especially rice, potatoes, beans, peas, and spices are the most common sources of Bacillus cereus
