Shigella spp is the bacteria that causes the illness known as Shigellosis.

The bacteria is found in the feces of humans that have the illness. the illness occurs when contaminated food or water is consumed. The bacteria can also be transmitted by flies from the feces to food supplies. While it only takes a small amount of this bacteria to make a person sick, high levels of the bacteria can be found in the feces for several weeks after the symptoms have ended.

Shigellosis symptoms include frequent bouts of water diarrhea (the main symptom), abdominal cramping, nausea, and vomiting. it is possible for some people to have either blood or mucus in their stool, and they may run a fever. Symptoms usually begin within three days of coming in contact with the Shigella bacteria.

The main food items that are linked to this illness are: foods that are easily contaminated by hands, such as salads containing temperature control for safety foods (potato, tuna, shrimp, chicken, and macaroni). The bacteria can also be found in food that has made contact with contaminated water, such as produce.

To help prevent the spread of this illness:

1. Exclude foodhandlers that have diarrhea and have been diagnosed with an illness caused by Shigella spp. from the operation.

2. Wash hands

3. Control flies inside and outside the operation.
