Teacher material for PCR Forensics

This lab will demonstrate how PCR can be used to hunt down the source of a food contaminant. We will use safe materials in a staged re-enactment of Listeria food poisoning. In early 2013, there was an outbreak of Listeria poisoning in Wisconsin in which a certain cheese was found to be contaminated. We will re-enact the PCR forensics hunt where your students will pretend to find the Listeria DNA from several pretend cheese samples.
