What is the scientific meaning of scavenger?
A scavenger is a consumer that eats the tissue of dead organisms that it does not freshly kill for itself. Lions and hyenas can act as scavengers but both will also consume fresh prey. Vultures are notorious scavengers but again will kill fresh prey if they can. Black bears can also act as scavengers. There are few if any organisms that act exclusively as scavengers.
Can ultraviolet sanitizers be used on food to prevent food poisoning?
Ultraviolet sanitizers only help kill off organisms on the surface of the food where they can be exposed to the ultraviolet light. Since many types of organisms that cause food poisoning are mixed into or are on the side of the food away from the light, the ultraviolet light cannot reach them and they remain intact and able to cause their nasty effects. Gamma radiation, which, like ultraviolet light is a form of electromagnetic radiation, can penetrate food and kill even organisms that are deep inside. As a result, irradiation with gamma rays is sometimes used to sanitize/sterilize food. Since ultraviolet light can kill those organisms that it can shine on, it is still useful for providing a more sanitary environment than one without it. It can sanitize surfaces where food is placed so that the food will not pick up germs, parasites, etc. from the surface. It won't totally prevent food poisoning, but it can lower the risk some.

Actually, antibacterial soap and antibacterial sanitizers usually do about the same job on bacteria, killing roughly 99.99% of germs. But if its a question of which should you rather use, I would choose sanitizers because soap leaves nasty residue called soap scum which can make your hands feel greasy and disgusting:(
