parasites |
single/multi celled org. that can only survive in a living creature (person/animal) passed through foods some are visible (roundworm) protozoa |
|
fungi |
yeast/moulds can spoil foods/make people ill |

|
what is the flow off food |
receiving storing preparing serving cooling (to store) reheating |
|
HACCP |
hazard analysis critical control point -analyzes where food contamination risks are |
|

prevent micro-organism delay micro-organism kill micro-organism |
|
how should facility be designed |
to minimize contamination, follow food flow/traffic |
