About 48 million people (1 in 6 Americans) get sick, 128,000 are hospitalized, and 3,000 die each year from foodborne diseases, according to recent data from the Centers for Disease Control and Prevention. Microbes in food are the culprits. The purpose of these protocols is to investigate the effectiveness of bio-based cleaners at reducing bacterial counts on lab stations.

# Student lab preparation
Students learn the difference between cleaning and sanitizing, then practice lab skills by creating agar plates that will serve them throughout the unit.
# Student lab station monitoring
Students monitor their lab station, and determine the quantity of microorganisms that survive on their lab stations.
# Bio-based cleaners
Students determine how effective bio-based cleaners are in killing common bacteria.
Foodborne diseases are a significant public health burden that are largely preventable. The FDA Food Safety Modernization Act (FSMA), signed into law by President Obama on Jan. 4, 2011, enables FDA to better protect public health by strengthening the food safety system. For the first time, FDA will have a legislative mandate to require comprehensive, science-based preventive controls across the food supply.
