Max Armstrong examines the significant regulation in California of pesticides on produce.

In a survey, regulators looked at produce sold by wholesale, roadside markets and terminal markets. The survey showed 97 percent of all the produce sold had no pesticide residue.

Plus, 98 percent of the produce examined by regulators labeled as grown in California had no pesticide residue at all.

However, when it comes to imported produce, 75 percent of all produce tested had illegal amounts of pesticide residue.

When it comes to produce imported from Mexico, 68 percent of the produce tested had pesticide residue outside of the legal limits. It was especially bad on tomatoes, green beans and snap beans. It doesn't mean it's not safe, but it had limits outside of the U.S. parameters.

Regulators found the produce grown in Ecuador, Greece and China had illegal limits of pesticide residue on them.
