Food has stayed too long at temperatures that are good for the growth of pathogens.

" Food is not held or stored at he correct temperature.
" Food is not cooked or reheated enough to kill pathogens.
" Food is not cooled correctly.

Transfer of pathogens from one surface to another or food to another.
" Contaminated ingredients are added to food that receives no further cooking. " Ready-to-eat food touches contaminated surfaces.
