A second bacterial pathogen, Clostridium perfringens, has been identified as part of the large outbreak in Louisiana that has been linked to jambalaya served at a softball fundraising event. Salmonella had already been isolated, but Clostridium perfrigens has now also been identified in patient stool samples. As of Friday, 125 cases were confirmed with 37 hospitalized. One death may also be linked.
While Salmonella effects are due to the infection is causes, Clostridium perfringes produces a toxin that causes the symptoms of diarrhea and abdominal cramps. It usually occurs in less than a day and those symptoms will normally last for 24 hours.
The issues of contamination will also be different. Salmonella is not heat resistant, so either the foods are undercooked or it will contaminate foods after cooking through cross contamination. Clostridium perfringens is a sporeforming pathogen, and its spores are heat resistant and thus can survive normal cooking conditions such as when making jambalaya. The key to prevention is proper cooling after the product is cooked. Basically, the spores survive cooking, but need warmer conditions for growth. In fact, at optimal growth temperature of 109F to 117F, C. perfringens can multiple every 10 minutes or so.
So clearly, the were some issues when people were making jambalaya....and this can be the case when people are cooking large quantities of food. For Salmonella to be an issue, the cooks either undercooked it, or they had sloppy procedures that allowed cross contamination. For the second bacterial pathogen - after cooking (or under-cooking), they did not properly cool the food which provided conditions for C. perfrigens growth. By regulation, foods such as this must be cooled from 135F to 70F within 2 hours, and from 70F to 41F within 4 hours. These conditions were established for C. perfringens. And if large quantities were made, cooling can be difficult.
