Salmonella is a genus of rod-shaped Gram-negative enterobacteria that causes typhoid fever, paratyphoid and food poisoning. The best known species are probably Salmonella enterica, which has numerous strains or serovars, and Salmonella typhi. The former is frequently responsible for food poisoning, especially from poultry. In the middle of the 20th century, it was a common contaminate inside and outside of eggs, but this is much less likely now. With the advent of egg washing, only salmonella passed from the hen's reproductive tract to the egg results in contamination. This is roughly on the order of one in ten thousand eggs.
