Students determine contamination levels of ground beef in different environments.
- Analytic Testing on Samples of Hamburger
- Ideal for Reinforcing Basic Laboratory Methods and the Importance of Sterile Procedures
- Material for One Lab Group or Student Provided
- Instructions Provided
- Students Learn about Food Safety
We are often cautioned to carefully prepare and store our food in order to avoid bacterial contamination. Now students can study the effects of improperly stored food with this lab activity and ground beef provided by the instructor.
The serial dilutions students perform determine the bacterial titer (level of contamination) in frozen, refrigerated, and room-temperature beef. It includes instructions and material for one lab group or demonstration.
Ordering information: This kit includes a bacterial spreader, sterile pipet, ethanol, tryptic soy agar, and petri dish. An incubator, hamburger sample(s), and microscope are required but not included.
