Bacteriology Science Fair Project

Bacteria in Poultry Meat

Bacteria in Poultry Meat | Science Fair Projects | STEM Projects
Ever wonder if irradiated chicken is really the safest to eat? In this project, you'll find out by testing the bacteria levels in fresh, frozen, and irradiated chicken.


The hypothesis is that the irradiated chicken possesses the least amount of bacteria.

Method & Materials

You will prepare 3 Petri dishes with agar, label them, and cut equal portions of fresh, frozen, and irradiated chicken parts. Then, you will pour disinfected water into each beaker and soak the meat for 10 minutes. Finally, you will swipe the swab over the respective agar surface and measure the diameter of the bacteria colony growth after 5 days.
You will need 3 agar Petri dishes, 3 disinfected swabs, 1 bottle of disinfected water, 3 sterilized chopping boards, 3 sterilized knives, 1 piece of fresh chicken parts, 1 piece of frozen chicken parts, 1 piece of irradiated chicken parts, 3 beakers, and 1 marker pen.


The results showed that the irradiated poultry meat had the least amount of bacteria growing on it, followed by the fresh chicken meat. The frozen chicken had the highest amount of bacteria growth.

Why do this project?

This science project is interesting because it tests the safety of different types of processed chicken meat and provides insight into the best way to prepare chicken for consumption.

Also Consider

Variations of this project could include testing different types of food or parts of the meat for bacteria, experimenting with different methods of thawing meat, or evaluating whether the type of packaging used for the meat affects the bacteria count.
