In 2012, 29 people across the United States suffered E. coli infections. The Centers for Disease Control and Prevention (CDC) linked most of these cases to raw clover sprouts at a specific restaurant chain. Which is the most effective way for the CDC to control this outbreak?
-Impose a fine on the farm that produced these clover sprouts.
-Distribute flyers about how to properly wash vegetables.
-Instruct the public to avoid the contaminated food source.
-Ask the public to stop consuming raw leafy greens.
