Isolated thunderstorms are when there are either thunderstorms present at the current time or there is a change for them to form, but they are scattered. These usually occur in the afternoon and the evening when the sun is out at its peak and heats up the atmoshpere.
For example, bacteria from the genus Salmonella are mostly facultative anaerobes, oxidase-negative, catalase-positive and gramnegative rods. Most strains are motile and ferment glucose with production of both acid and gas.
In other data, more than 60% of animal processing plants and 37% of vegetable processing plants tested positive for Salmonella.. Pet foods are cooked to kill Salmonella bacteria, but where the processing plant is contaminated, food is exposed to contamination after cooking.
