Watch out for the 2012 'Dirty Dozen'

Watch out for the 2012 'Dirty Dozen'

Apples and celery are still agriculture’s dirtiest pieces of produce, according to the Environmental Working Group’s annual “Dirty Dozen” report. The report names the fruits and vegetables ranking highest in pesticide residue.

Cucumbers were added to the 2012 Dirty Dozen, while Kale and collard greens were moved from the list to join green beans in a new “Plus” category.

The category was created this year to highlight crops that did not meet traditional Dirty Dozen criteria but are still commonly contaminated with organophosphate insecticides, which are toxic to the nervous system.

Also included on the Dirty Dozen list are:

1. Apples

2. Celery

3. Sweet bell peppers

4. Peaches

5. Strawberries

6. Imported nectarines

7. Grapes

8. Spinach

9. Lettuce

10. Cucumbers

11. Domestic blueberries

12. Potatoes

And on the "Dirty Dozen Plus" list:

+ Green beans

+ Kale/collard greens

The fruits and vegetables with the least amount of pesticide residue make up a list of the “Clean 15":

1. Onions

2. Sweet corn

3. Pineapples

4. Avocado

5. Cabbage

6. Sweet peas

7. Asparagus

8. Mangoes

9. Eggplant

10. Kiwi

11. Domestic cantaloupe

12. Sweet potatoes

13. Grapefruit

14. Watermelon

15. Mushrooms

Although some switched spots within the ranks, the fruits and vegetables included on the lists stayed fairly consistent from the 2011 report.

The EWG report is based on pesticide residue data collected by the U.S. Department of Agriculture and the Food and Drug Administration, which tested samples as they normally would be eaten — after being washed or peeled.

The chronic health effects of pesticide intake have not been widely studied, but Chensheng Lu, an associate professor of environmental exposure biology at the Harvard School of Public Health, said the toxins appear to be connected to a prevalence of diseases, including cancer. And some studies suggest pesticide intake, especially in the prenatal stage, can cause neurological developmental problems in infants, Lu said.

“Knowing that this chemical is designed to kill (certain) organisms, you have to be careful ingesting it,” he said.

With the release of this list, the EWG suggests consumers reduce their exposure to pesticides as much as possible by purchasing organic versions of the Dirty Dozen. Organic produce is grown using materials of plant or animal origin, instead of chemicals.

Organic produce is often thought of as more expensive than conventionally grown produce, but Lu said an increased demand in recent years has led to lower prices.

“You may want to think about saving money just for buying organic apples and not buying organic other stuff,” Lu said. “You switch your resources for the high risk produce and buy organic for those.”

For the first time this year, the USDA also collected data on pesticide residue in baby food, finding many of the studied samples to be contaminated with organophosphate pesticides. In its report, the EWG stresses the importance of accelerating testing of baby foods and asks the Environmental Protection Agency to focus on reducing the organophosphate pesticide exposure allowed for Americans, especially infants.

      With rampant contaminated vegetables and fruit, this sounds like even more reason to eat animals...

      Since you are bringing religion into the argument, please re-read Genesis. Man/Adam was given dominion over the animals to do with as he sought fit to do. God is also not female which is why Jesus calls Him Our Father. Ignorant statements convince no one.

      They are heavily contaminated with pesticide so not worth buying unless you get organic or grow your own.

      Even after repeated washings residue of Dihydrogenmonoxide can still be found on fruits and vegetables. It's time that people wake up to this danger!

  7. Simply Not True

    The EWG's claims about residues are bogus. Check out what the folks at UC Davis have to say:

    "In summary, findings conclusively demonstrate that consumer exposures to the ten most frequently detected pesticides on EWG's “Dirty Dozen” commodity list are at negligible levels and that the EWG methodology is insufficient to allow any meaningful rankings among commodities" http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3135239/

    The EWG wants hard-working Americans to buy more expensive products based on false studies.....I wonder why???

    the EPA diffinition of a pesticide is any thing that attracts , repels, or kills a pest. If a person were to use a peice of the clean fruits and vegetables – even – organically grown- on a mouse trap then it would be magically transformed into a pesticide by technicle definition . Organophosphates are somthing to be concerned about though – you may or may not believe they cause cancer – well they can make you sick and it doesnt take as long as cancer , if you are injesting them they wil start to slow down your bodies functions – by blocking nerve impulses from your nerves to your muscles . organophosphates are supposed to be banned in the U.S. but many countries still use them. I am not against the use of pesticides – some of the ' green products are non toxic to fish and birds – and farmers need to protect their proffits and our food source – but the way to do it isnt allways a simple path. The word pesticide should be defined to the public in terms we can relate to – with specific rating scales – and eliminate non toxic products from its definition.

    and for you that say just wash you fruit , if you spray foods that are still growing or are porous then you will find the organophosphates – if they were solvent based – in the food not just on the food.

    Just wash your produce -really really- well before eating it. Especially when it comes to vegetables, I generally soak mine in cool water for about 10 minutes before eating it, and use a salad wringer to make sure the residue is completely washed away.

    I'm also concerned about the "inert" ingredients in pesticides (which can be more than 50% of the pesticide chemical), like benzene's and other PAHs that can cause cancer. The secret part of the pesticide recipe/residue.

    Testing can never reveal all attributes. Most organic produce has superior taste, which is not noticed by all humans, especially those who smoke. Those with a superior pallet readily detect the distinct difference between industrially grown food fine organic grown food. Think I'm wrong? Explain to me then why wine can have such distinct flavor and olfactory notes depending on how and where the grapes were grown. ORAGNIC IS SUPERIOR IN ALL WAYS YOU INDUSTRY HAcks!!!!!! I AM THE Superior informed all-knowing and most honest TRUTH KING of all the lesser-informed so I naturally have to be completely correct on this fact.

    To wash veggies I read that you should add a little apple cider or white vinegar to the water to clean them thoroughly.

    Celery is a long-season crop that can be tricky to grow, some might say, the trickiest of all. It likes fertile soil, cool temperatures, and constant moisture. It will not tolerate heat and can be hard to transplant. Summer crops in the north and winter crops in the south make celery a year-round producer. All the work is worth it when you harvest crunchy, green stalks.';..:

    Rihanna has won a permanent ban against Topshop to prevent the retail chain selling T-shirts using an image taken at an official video shoot for We Found Love in 2011 by a freelance photographer. In an earlier hearing Mr Justice Birss had allowed a claim in passing off that because the photo used was very similar to imagery on her album ‘Talk That Talk‘, consumers would likely think it was an officially endorsed product, which it was not.
