"Dirty Dozen" fruits and vegetables

[ErikJ]

What Types of Produce Have the Highest and Lowest Levels of Pesticide Residues?
A study by Consumers Union, the publishers of Consumer Reports magazine, examines and rates the residual levels of pesticides on many common fruits and vegetables. A report by the Environmental Working Group, using data from the U.S. Food and Drug Administration, has found that much of the health risks associated with pesticides are concentrated in a relatively small number of fruits and vegetables. The list below is compiled from these reports.


Apples top 2011 'dirty dozen' list, says group
Apples are the most chemically contaminated produce, says a new report by the Environmental Working Group, a non-profit focused on public health.

The report suggests buying organic apples instead of conventional, and names other fruits and vegetables that rank highest in pesticides. Organic produce is grown using materials of plant or animal origin, instead of chemicals. On the "dirty dozen" list are:


1. Apples

2. Celery

3. Strawberries

4. Peaches

5. Spinach

6. Imported nectarines

7. Imported grapes

8. Sweet bell peppers

9. Potatoes

10. Domestic blueberries

11. Lettuce

12. Kale/collard greens

The group also lists the "Clean 15," or those that rank lowest in pesticide residues. These are:

1. Onions

2. Sweet Corn

3. Pineapples

4. Avocado

5. Asparagus

6. Sweet peas

7. Mangoes

8. Eggplant

9. Domestic cantaloupe

10. Kiwi

11. Cabbage

12. Watermelon

13. Sweet Potatoes

14. Grapefruit

15. Mushrooms

"Though buying organic is always the best choice, we know that sometimes people do not have access to that produce or cannot afford it," EWG President Ken Cook said. "Our guide helps consumers concerned about pesticides to make better choices among conventional produce, and lets them know which fruits and vegetables they may want to buy organic."

However, United Fresh Produce, the trade association representing produce companies, calls the report "misleading."

In a statement to CNN, the group said:

"At a time when medical experts strongly urge Americans to realize the health benefits from eating more fruits and vegetables, it is irresponsible to mislead consumers with a sensational publicity stunt disguised as science. While its authors admit the 'health benefits of a diet rich in fruits and vegetables outweigh the risks of pesticide exposure,' the Dirty Dozen list will almost certainly discourage many people from eating the recommended amounts of fresh produce and potentially diminish the nutrition and health of millions of Americans."


How To Make Produce Safer

Buy Organic
Produce which is "Certified Organic" will cost more, but is your best assurance of pesticide-free status. Although the chart above is useful, it is not 100% accurate; growing methods can change from year to year, and country-of-origin considerations make it more difficult to know exactly what you're buying. For example, the US exports annually 100 - 150 million tons of banned (in the US) pesticides, and then imports fruit which may be grown using these pesticides. Buying organic, in-season produce from your local market is the best assurance of pesticide-free produce.

Vegetable and Fruit Washes
Commercial vegetable and fruit washes are available which are formulated to remove chemical residue from produce. Examples are Environné and Vitanet, available online or at your local health food stores and some supermarkets. You can also make your own produce wash using a very diluted solution of mild dishwashing detergent (1 tsp detergent per gallon, or 4 liters, water).
For grapes, strawberries, green beans, and leafy vegetables, swirl the foods in a dilute solution of dish detergent and water at room temperature for 5 to 10 seconds, then rinse with slightly warm water.
For the other fruits and vegetables, use a soft brush to scrub the food with the solution for about 5 to 10 seconds, then rinse again with slightly warm water.

Peel Fruits with Higher Residue Levels
Peeling fruits, especially peaches, pears and apples, will help remove residues. Be sure to keep the peelings out of the compost. Some pesticides permeate the skin of the fruit, so this method does not guarantee residual free produce in all cases.

Grow Your Own
Looking at the list of most contaminated fruits and vegetables, you can chose to grow some of these yourself. Even a small backyard plot can be very productive for family use. Bell peppers, for example, are easy to grow in most hot or temperate climates, especially when grown in a garden cloche. Green beans and grapes can be grown vertically on trellises which can also serve as a shade provider during the summer months. Apples can be grown in most climates, and columnar varieties can even be grown in pots on the deck or rooftop. See our page on fruit trees. Peaches can be grown in the backyard in warm to hot climate zones, but often require a method of covering to protect the tree from rain-borne disease. Spinach and cucumbers are easy, if you have the ground space. You can plant one or two of these crops in your yard and encourage a neighbor to grow others - then share the harvests.

Tips
~ Although apples rank high in pesticide residue, apple juice ranks low. Apple juice is a good substitute for non-organic apples.
~ The residue levels in canned peaches are drastically lower than for fresh peaches. The processing requires vigorous washing which removes most residues from the skin. Also, different varieties of peaches are grown for canning, which require less pesticide to grow.
~ Sprouts are easy to grow in the home, very inexpensive and highly nutritious. Sprouts may be the simplest source of organic produce for you and your family.
~ Some of the fruits and vegetables which rank low on the pesticide residue scale may have higher rates of pesticide residue if they come from certain countries. Ask the produce manager in your local supermarket for country-of-origin information.
~ Cherries from the US are three times more contaminated than their imported counterparts, which are among the cleanest fruits and vegetables analyzed. Cherries contain a compound known as ellagic acid which counteracts carcinogens, so it's worthwhile to seek out a source of imported cherries if you live in the US or Canada.
~ Are pesticide residues less of a problem in canned and frozen fruits and vegetables? Probably, although most of the research has been done by the food industry. The washing and blanching to prepare fruits and vegetables for canning or freezing removes or destroys approximately 80-90% of pesticide residues, according to the U.S. based National Food Processors Association.

1. First thing I learned when traveling in rural areas of the tropics -

Things with skins that are inedible and removed are ok. Things with thin, edible skins are not necessarily ok, even if you remove the skins. Things where you eat the skins are definitely not ok. This list is pretty consistent with that.

The mushroom being on the ok list seems questionable to me. I was once near one of the biggest mushroom farms in the country. The smell was unlike anything I have ever known. Apparently they cover the mushrooms with chicken manure - lots of it. It's hard to believe that they don't have significant levels of pesticides.

2. Ah...it's better to eat any veggie or fruit

than dead flesh any old day!

3. Not so; even peeled apples have residue

Which is the scary part. But this article says apple juice is OK so that implies the fiber has the residue attached. I was going to juice a bunch of apples today and wondered if I should peel them first. So I googled it and the articles recommend peeling because they use so many pesticides that it is embedded in the peel. So I will peel them at least. I'll try to buy organic from now on I guess. Strawberries and blueberries too.

I wonder about bananas and carrots which arent on either list. I eat a lot of bananas but figure they would be OK as they have a thick peel like you say. Carrots I will continue to peel before juicing.

I also eat a lot of yams so hopefully like sweet potatoes are safe. I peel them as well. I like to juice sweet peas too which are also on the safe list.
