Reproduction

Salmonella reproduce by binary fission. This is an asexual way to reproduce, and only produces two, generally identical cells from the original one. This reproductions occurs at a rapid rate, producing once every 20-40 minutes if the conditions are prime. The new cells then follow the lytic cell cycle to continue reproducing.

Keeping salmonella in a cooler place inhibits growth, but doesn't kill the bacteria. Storing chicken in the fridge won't let the bacteria grow, but the chicken will still have salmonella.

Salmonella spreads very quickly through infected animals, since infected chickens can pass salmonella bacteria on to their eggs. Even touching salmonella carrying foods or surfaces can get you infected.
