Worst Produce for Pesticides

Don’t Buy Dirty

When it comes to produce, buying organic means not buying chemicals and pesticides with your food.

June 13, 2012

People can’t always buy organic for a variety of reasons: The local store may have limited supplies, they lack variety or cost is a consideration. But whatever the reason—or excuse—shoppers should be aware that some produce at the grocery store is more pesticide-laden than others.

Every year, the nonprofit Environmental Working Group tests all manner of produce for pesticides and chemicals to compile its list of the “Dirty Dozen,” and “Clean 15” foods. By using the list to choose the foods to buy organically, EWG says consumers can substantially lower their pesticide intake.

You would be surprised at the level of pesticide contamination found in common, conventionally grown food. According to EWG:
• Every sample of imported nectarines tested positive for pesticides, followed by apples (97.8 percent) and imported plums (97.2 percent).
• 92 percent of apples contained two or more pesticide residues‚ followed by imported nectarines (90.8 percent) and peaches (85.6 percent).
• Some 96 percent of all celery samples tested positive for pesticides, followed by cilantro (92.9 percent) and potatoes (91.4 percent).
• Nearly 90 percent of celery samples contained multiple pesticides, followed by cilantro (70.1 percent) and sweet bell peppers (69.4 percent).
• Hot peppers had been treated with as many as 97 pesticides, followed by cucumbers (68) and greens (66).

If that doesn’t underscore the need to “buy organic,” I don’t know what does. You might want to clip this out and keep it with you for handy reference when you go shopping.

According to EWG, if you choose five servings a day from the “Clean 15” instead of the “Dirty Dozen,” you can lower the volume of pesticide you consume daily by 92 percent. You’ll also eat fewer types of pesticides. Picking five from the “Dirty Dozen” would cause you to consume an average of 14 different pesticides a day, the EWG states. If you choose five servings from the “Clean 15,” you’ll consume fewer than two pesticides per day.

Additionally, because genetically modified, or GMO, seeds are more often used in conventionally raised corn, and the United States (unlike other countries) does not require GMO labeling, EWG recommends consumers only buy organic sweet corn; GMO seeds are banned in organic growing.

Organic practices lessen E. coli threat

 

June 9, 2011

Organic practices lessen threat of disease

The news this week that a deadly outbreak of E. coli bacteria in Germany was from an organic farm raised flags with me, as much for its improbability as for its deadly nature.

Since those first reports, the German government has backed off its claim that an organic farm produced the outbreak.

While it’s possible for any farm – including an organic farm – to have produce infected by the bacterium, and consumers should always wash produce from the grocery, regardless of source, it’s less likely for organic produce for a variety of reasons.

First, the incidence of virulent strains of E. coli is a direct result of conventional (not organic!) farming of beef, where animals are “finished” on corn.

Ruminants are not naturally equipped to digest corn and it leads to bacteria (E. coli among them) being excreted from the gut. When coupled with the common practice of conventional agriculture (not organic!) to feed antibiotics to farm animals, virulent strains resistant to treatment are formed.

These bacterium are found in the manure of conventionally raised farm animals (not certified organic!) and that manure is often used to fertilize crops.

Here is where the possibility of E. coli can enter the organic food train, depending on the producer:

In certified organic vegetable crop production, strict manure handling is required.

Specifically: The U.S. regulations for organic production require that raw animal manure must be composted unless it is applied to land used for a crop not intended for human consumption; or is incorporated into the soil not less than 120 days prior to the harvest of a product whose edible portion has direct contact with soil; or is incorporated into the soil not less than 90 days prior to the harvest of a product whose edible portion does not have direct contact with the soil surface or soil particles. See 7 CFR 205.203 (c)(1) and (2).

Residual hormones, antibiotics, pesticides, disease organisms and other undesirable substances can be eliminated through high-temperature aerobic composting.

So, presumably, E. coli would be eradicated in certified organic crops – if manure is properly composted or incorporated.

Again, I’m not saying it cannot occur, but, for producers of organic crops, the likelihood of transmitting E. coli is much smaller.And, for those (such as in our case, for example) where only composted horse manure or composted grass-fed or organic cow manure is used, not “raw” manure, or from industrial agriculture confined and corn-finished herds, the likelihood drops to virtually zero.

Me? I say: Eat organic, eat local! Know your farmer. Compose your own compost and manures from known – or OMRI verified – sources.

For the home organic gardner: Anyone who is actually growing his or her own food and uses manure would do well to read the book: Holy Sh*t: Managing Manure To Save Mankind by Gene Logsdon (Chelsea Green, 2010, $17.50).

Why store-bought tomatoes taste like cardboard

April 1, 2011

Store-bought tomatoes taste like cardboard? Here’s why

People who buy fresh local organic produce are often astounded at the rich, succulent flavors that seem to explode in the mouth.

There are a variety of reasons for this, some of them quite technical, not only involving the fertility and trace elements in soil, but also the chemicals plants use to defend themselves when left alone (rather than grown in industrial farming monocultures with poisonous pesticides, herbicides, etc.).

It’s often most pronounced when tomato season arrives and people ask, why do grocery tomatoes taste like cardboard?

That also is for a variety of reasons, including the above and also the fact that most commercial tomatoes are hybrids grown with a preference to be a certain size, weight and shape so that they can be shipped in uniform boxes and also so they will all ripen at the same time (determinate) and have a long shelf life, rather than taste. Add to this the timing of picking.

For tomatoes to be shipped, they are picked at what’s called the “breaker” or “mature green” stage, which is not mature at all.

It’s when the tomato is showing the first hint of blush on the skin. Only 5 percent of the potential flavor of the tomato is in the fruit!

Yet, this is the stage from which the tomato you buy in the grocery is picked, so that it can be trucked across country, or countries, held in warehouses, distributed to stores sites, displayed on shelves and, ultimately, bought by a consumer.

So, what do we want in a tomato?

Here in Mississippi, in addition to flavor, we want the plant to survive the hot, humid weather.

Most of our tomato problems are because it’s too moist, and you get all kinds of rots and blights, or because it’s too hot (more than 100 degrees) and the fruits won’t “set.”

Here are a couple of varieties to consider (though by all means, if you are successful with what you are growing, stick with it!):

•Homestead24 (certified organic; for hot, humid weather, from Florida);

•Neptune (certified organic, hot, humid, from Florida);

•Cherokee Purple (heirloom from Tennessee; hot weather tolerant);

•Arkansas Traveler (heirloom, hot, humid).

If not available at a seed store, near you try: TomatoFest (http:// store.tomatofest.com/); Box 628; Little River CA 95456.

Faith, mustard seeds and jets. During U.S. Navy Secretary Ray Mabus’ recent visit to Mississippi, he mentioned that the Navy is venturing into biofuels to end reliance on fossil fuels.

I asked him if it was corn-based (ethanol hikes food costs and is nonsustainable, using more energy to produce than it produces) and he said, no, it was a type of mustard seed. I thought maybe he had gotten his facts confused with a biblical verse.

But, intrigued, I inquired further, and his office reported it’s specifically Camelina sativa, and sent the following facts:

•Camelina is a genus in a flowering plant family related to the mustard plant, and its seeds can be refined into a biofuel.

•It can be used as a rotation crop or on fallow land.

•It is naturally occurring in all 50 states except Hawaii.

•It’s currently cultivated in Florida: 7,000 acres.

•On Earth Day last year, the Navy flew an F/A-18 Hornet – named the “Green Hornet” – 1.2 times the speed of sound on a 50-50 blend of camelina and JP-5, and is testing and certifying all its aircraft on the same blends.

This might be a cash crop for Mississippi farmers.

It’s certainly worth exploring.
