Shigellae are Gram-negative, non-motile rods. Shigellae are transmitted by the direct faecal-oral route. As an outcome, food can possibly be contaminated through the grimy fingers of patients or carriers. The transfer of Shigellae by flies rearing on faecal matter has been laid out as a vital transmission route during outbreaks. Shigella can be found in surface waters and furthermore within contaminated drinking water. Isolation of Shigellae from food sources is a challenge. Isolation and identification of Shigella from food sources by culture needs a few days relying upon the food matrix and storage conditions. Shigella species can be grown out by the resident bacterial species found in food varieties, which might reflect the standard low numbers of the organism present in food varieties. One more factor that decreases the possibility of isolating Shigella from food varieties might be the physiological condition of the microbe at the hour of analysis. Ecological circumstances could influence its capacity to either grow or survive in any food matrix.
