Preventing Foodborne Illness: Bacillus cereus

Karuna Kharel, Kiara S. Bookman, Renée Goodrich Schneider, Rachael Silverberg, Ploy Kurdmongkoltham, Bruna Bertoldi, and Keith R. Schneider

Bacillus cereus is a Gram-positive, facultative, anaerobic bacterium characterized by large rod-shaped cells and an ability to form heat-resistant endospores. Since this bacterium is commonly widespread in the environment and is often found in soil, it is naturally present in a wide range of food products of both plant and animal origin. B. cereus grows best in a temperature range of 39ºF (4ºC) to 118ºF (48ºC). Optimal growth occurs within the narrower temperature range of 82ºF (28ºC) to 95ºF (35ºC) and a pH range of 4.9 to 9.3 (FDA 2012).

Preventing Foodborne Illness Associated with Clostridium perfringens

Karuna Kharel, Kiara S. Bookman, Renée Goodrich-Schneider, Ploy Kurdmongkoltham, Bruna Bertoldi, and Keith R. Schneider

The bacterium Clostridium perfringens causes one of the most common types of foodborne gastroenteritis in the United States, often referred to as perfringens food poisoning (FDA 2012). It is associated with consuming contaminated food that contains great numbers of vegetative cells and spores that will produce toxin inside the intestine. There are two forms of disease caused by C. perfringens: gastroenteritis and necrotizing enteritis. The latter disease, also known as pig-bel disease, is not common in the United States. It is often associated with contaminated pork and can be very severe (FDA 2012).
