Lowering Your Risk of High Pesticide Levels

With Organic Raisins
by Joel Fuhrman, M.D.

Lowering Your Risk of High Pesticide Levels

Each year, the Environmental Working Group (EWG) uses data from the USDA Pesticide Data Program (PDP) to create their Dirty Dozen and Clean Fifteen rankings of fruits and vegetables. The Dirty Dozen list allows shoppers to see, at a glance, which conventionally grown items – such as strawberries and apples – contain high levels of pesticide residue and should be avoided, in favor of organic versions. This year, EWG highlighted a problem with a popular item: raisins.

The Pesticide Problem

The USDA measures pesticide residues on thousands of fruit and vegetable samples every year. Each year, the Environmental Working Group (EWG) uses that data to rank fresh produce based on a collection of metrics, such as the percent of samples with detected pesticides, the average number of pesticides Lower Your Risk of High Pesticide Levels with Organic Raisins found, and the average concentration of pesticide.

In 2020, EWG published its list as usual but added a notice about a food not usually included in its rankings – raisins. EWG usually only considers fresh produce in their rankings, however, USDA tested raisins in 2018 (for the first time since 2007), and based on EWG’s ranking methodology, raisins would be #1 on the Dirty Dozen list if they were included.

Raisins Gone Rancid

The EWG found raisins to be a particular concern for several reasons:

  • The frequency of pesticide detection – 99 percent of samples had residues of at least two pesticides, more than any of the 47 fresh produce items tested.
  • Raisins are a common food for children, who are likely more vulnerable to potential harmful effects of pesticides than adults.1

What pesticides are we talking about here?

The specific pesticides detected on most raisin samples were a neonicotinoid pesticide (imidacloprid) plus bifenthrin and tebuconazole, which have shown developmental neurotoxicity in animal studies.2-4

Choose Organic

Organic raisins are better than conventional. Raisins are a dried fruit, which means their sweetness is concentrated. You should limit your consumption of any dried fruit, compared to fresh fruit. If you are going to eat raisins, it makes sense to choose organic, especially for children. Fumigant residues are not measured as part of the USDA’s Pesticide Data Program, but organic production forbids the use of fumigants.5  The gases used for fumigation may be hazardous for workers, the environment, and consumers alike.

Eating vegetables and fruits, whether organic or conventional, protects against chronic diseases. Even the highest pesticide residue levels detected on produce are very far below the chronic reference dose, the estimated dose of a chemical a person could be exposed to daily throughout life without any harmful effects.6

In addition to the environmental benefits of organic agriculture, there may also be health benefits. That’s why I recommend choosing organic produce whenever possible.
