Science and Our Food Supply: Investigating Food Safety from Farm to Table

ADVANCE PREPARATION

• 

Gather a collection of materials for students to use in their lab 

designs. 

• 

Put Glo Germ™ (or cooking oil and cinnamon) on your right hand 

just before the students enter the classroom. 

• 

20% of consumers don’t wash their hands  

before preparing food. 

• 

If you don’t wash your hands, you could  

cause infant diarrhea! Your hands can pick up 

bacteria from the following things and spread 

bacteria to a baby: 

– Diapers;  

 

– Raw meat, poultry, eggs, and seafood;

– Animals such as dogs, cats, turtles, snakes,  

and birds; and  

– Soil.

Note: For more handwashing tips, see the 4 Cs 

section in the Food Safety A to Z Reference Guide.
