"Green" Shopping Bags Carry More Than Food

Reusable shopping bags are a must-have for environmentally minded shoppers. But a new study suggests that those who use "green" totes may get more than they bargained for, namely, a whole lot of bacteria.

The study, conducted by researchers at the University of Arizona, Tucson and Loma Linda University in California, found "large numbers" of bacteria in every reusable bag they tested. E. coli, specifically, was found in about 12 percent of the bags examined.

More after the jump...
Through interviews with shoppers carrying reusable bags, they also discovered that only a small number -- just 3 percent -- wash their bags, and that the bags are often used for multiple purposes.

The researchers grimly assessed that, "reusable bags can play a significant role in the cross contamination of foods if not properly washed on a regular basis."

So, if you want your reusable bags to be filled with a bounty of food, and not a bounty of bacteria that can cause foodborne illness (of which there are about 76,000,000 cases of in the United States every year), you'll need to wash them. Hand or machine washing, the study notes, reduces the bacteria in bags by more than 99.9 percent.

Washing is so effective, in fact, that the researchers recommend stores be required to put printed instructions on reusable bags "that they be washed between uses or the need to separate raw foods from other food products."

Libba Letton, a spokesperson for Whole Foods, said the grocery chain does not require such instructions on the reusable bags it sells, and she's not certain they're needed.

"It's not surprising to find out that bags need to be cleaned every once in a while," Letton said. "Like all reusable items, reusable bags need to undergo some reasonable care to ensure cleanliness."

You can not legislate or totally account for stupidity with instructions.

I would bet the research done on this question was paid for by the plastic bag companys. A little contamination will help the body build resistive antibodies and that will prevent desease. plus the only time I have seen people put unwraped food item in a reusable bag is at the farmers market and if you are not washing that produce befor you eat it you are to dumb to live

Studies have shown that a flush can carry airborne up to 6 feet.
It might be wise to have a barrier of some type between your sink/vanity and the toilet itself.

Did you also know that your toothbrush has fecal matter on it? So instead of us getting important updated health new such as wash your reusable bag we get insulted by postings about being stupid. Well "Barbara" do you bleach out your toothbrush prior to using it? Ok, we are all trying to be green, it's a good thing and there are pro's and con's to everything in life. So we need to recall how to be green or some of us need to learn how to be green. If you think Al Gore is a tree hugging hippie too bad we are busy trying to save what's left of this world for our future Grandchildren so on and so forth.

Just waking up here I think it's funny that neither of you who even bothered to reply to me mentioned the misspelling of some of the word's grammer a bit off but hey I was waking up to find this. You know everyone has skeleton's in their closets. So if have time to sit around picking apart people as you have done to someone you don't even know hey go at it. God only knows I do not want to take your only form of entertainment away for either of you. Bottom line idot's believe it or not maybe not in our life time but this somewhat beautiful earth is going to die. If you chose to believe it great if not then see you in hell....MF :o) This is the standard reception I would get from idot's like you when I was 17 yrs old in California trying to raise the awareness of the status of the earth with the Sierra Club and that was 40 plus years ago. It is sad to see the status quo. "Nuke the whales"?
