TRANSCRIPT
Where are pesticides found? • 70% of food sampled by the USDA
contained pesticides1 • 1/3 of private drinking water wells in
Wisconsin contain pesticides2 • 94% of Americans have measurable
pesticide metabolites in their urine3
Which U.S. grown crops have the highest and lowest pesticide risks?
4
To reduce your pesticide exposure… • Buy fruits and vegetables grown in the U.S.10 • Wash fruits and vegetables before eating. This
removes some pesticides, but not all of them. • Choose fruits and vegetables from the Clean 15 • Purchase food grown without pesticides, especially for
foods which have tested high for pesticide residues • Grow your own food without using pesticides
Healthy Eating: Avoiding Pesticides in your Food
In Wisconsin: • The number of
organic farms doubled in the last decade
• Now, 1% of farms and acres are certified organic
Over 1,100 organic farms in Wisconsin9

Pesticide use on crops grown in Wisconsin
Lower pesticide exposure from organic diet8
When children began eating organic fruits, vegetables, juices, and grains the levels of some pesticides in their urine dropped more than four-fold to undetectable levels in a few days.
“Organic” means grown without synthetic pesticides “Natural” has no definition, so can be used on anything
Babies & children are more vulnerable to pesticides7
• From age 1-5 children consume 3-4 times more food per pound of body weight than adults
• Babies and children to at least age 7 have lower levels of detoxifying enzymes than adults7
• Children with higher levels of organophosphate (OP) pesticides were more likely to be diagnosed with ADHD;11 children whose mothers had higher levels of OP pesticides in their urine when pregnant had lower IQ scores at ages 2-3 and 6-9. OP pesticides are found on apples, bell peppers, cranberries, grapes and other produce.12
