The bacteria then multiply within the body and attack the nervous system. Fever, chills, headache, backache, sometimes abdominal pain and diarrhoea; 12 hours to three weeks; may later develop more serious illness in at-risk patients (meningitis or spontaneous abortion in pregnant women); sometimes just fatigue. Food-borne microorganisms are major pathogens affecting food safety and cause human illness worldwide as a result of consumption of foodstuff, mainly animal products contaminated with vegetative pathogens or their toxins. Plants use passive defence such as poisons and distasteful substances such as sulphur compounds in garlic and onions. As the bacteria are incredibly rare its unlikely that the illness will develop, especially because there are strict controls in place for manufacturers of canned foods.
