Produce 'washes' as effective as water

Produce 'washes' as effective as water Wednesday, January 1, 2003

By DON THOMPSON Associated Press Writer

SACRAMENTO -- Commercially marketed "produce washes" that claim great efficiency in removing pesticide residue from vegetables are in fact not much more effective than plain tap water, according to a new study by University of California, Riverside, researchers.

Robert Krieger, a toxicologist with the university's extension office, was intrigued reading advertising that such washes are as much as 10 times more effective than water -- claims he determined are a mathematical impossibility because water itself is so efficient.

The research comes amid increased consumer concern over pesticides left on produce.

At least one popular restaurant chain -- TGI Friday's -- used to advertise on its menus that its vegetables were washed with Procter & Gamble's Fit Fruit and Vegetable Wash. Proctor & Gamble marketed not only the wash, but a Fit Soak Bottle and Fit Washing Kit containing a colander and bowl in which to wash the produce.

Yet, "clearly this study shows that there is no reason to spend extra money on these washes when water is just as effective," Krieger determined.

The research is to be formally published in February's Bulletin of Environmental Contamination and Toxicology.

The study focused on one of the lesser claims, that Procter & Gamble's Fit wash was "98 percent more effective than water at removing pesticides most commonly found on produce."

"When you make a statement that it's (nearly) 100 percent better than water, put your money on the table -- you're wrong," Krieger said. "As soon as they did that, they created unrealistic expectations among the consumer."

The research triggered questions, but no action, from the Federal Trade Commission.

However, Procter & Gamble spokeswoman Melissa Johnson said the company discontinued the product last year as "strictly a business decision" to concentrate on more popular products. In a summary of its research, the company said its claims were confirmed by independent laboratories in 1995 and 1999, using California produce.

Other companies' vegetable washes, meanwhile, advertise claims that they are three, four, five or even 10 times more effective than water.

That's mathematically impossible, because water alone removes much of the pesticide residue, Krieger said.

"Water is a pretty effective solvent," he said. "If water takes off (for instance) 50 percent, you can't take off 10 times more than that because that's 500 percent."

Researchers conducted their study with samples of California fruit that had been routinely sprayed with pesticides in the field.

They found that water removed 39 percent of pesticide from one group of fruit, while Fit removed 45 percent.

In a second study, water removed 81 percent and Fit removed 90 percent of one type of residue, while the split was 18 percent and 39 percent for a different pesticide remnant, respectively.

In addition, researchers had 10 households run the water-versus-wash tests over several days.

"We wanted to really see if it made a significant difference" under real life and laboratory conditions, Krieger said. "The results were exactly the same."

All the pesticide residue levels -- even on the unwashed produce -- were well below federal environmental and health guidelines, Krieger said.

The study tracks a 2000 World Health Organization summary finding that water alone substantially reduced pesticide residue on fruits and vegetables.

Nothing gets past this reporter. Fit was discontinued over 16 months ago.

Yes, that fact is mentioned in the article. It's a good heads-up for consumers when the next miracle product to hit the shelves.

I bought some of that. Number one, it's expensive. Number two, I didn't see/smell/taste any difference. Number three, it's a pain in the arse to remember to use it.

If they pulled it 16 months ago, then the bottle I have must be two years old. LOL!! And it's only half empty!

Now all I need to find out is which group(s) funded the research and what philosophies and interests they embrace. That will tell me how much significance I should attribute to this research .

I think a capful of hydrogen peroxide and lemon juice works just as well. I have used this both internally and externally.
