Reusable Totes Can Harbor Bacteria and Make You Sick

Eco-friendly reusable totes can harbor bacteria that makes you sick.

You're trying to do your bit to save the planet by using eco-friendly grocery bags, but if you don't clean those reusable totes frequently and properly, you may be putting your family's health at risk for contracting nasty food-borne illnesses, such as salmonella, listeria, and E.coli.

A new survey shows that only 15% of Americans regularly wash their reusable grocery bags, according to the Home Food Safety program, a collaboration between the Academy of Nutrition and Dietetics and ConAgra Foods. Dirty grocery bags create a breeding zone for harmful bacteria that can contaminate your food. Each year, 48 million Americans contract food poisoning from contaminated foods.

5 Steps to Avoid Foodborne Illness

How can your reusable grocery bags make your family sick? "The pathogens on meat and poultry are easily spread because many people, trying to be eco friendly, don't use plastic bags for their vegetables," says Pat Kendall, PhD, RD, associate dean for research at Colorado State University's College of Applied Human Sciences. "Those plastic bags in the produce section are there for sanitary reasons." Instead, veggies get thrown into the grocery cart, which harbors its own germs, then packed into a reusable grocery bag along with the meat and poultry.

It's not just a question of blood or other liquids leaking out of the meat or poultry packaging. "E.coli may live on the meat packaging itself, given the way it's handled when it's prepared and wrapped," Kendall says. The pathogens form a biofilm -- a protective covering for a group of bacteria that can survive in a fairly arid climate -- like that of your reusable grocery bag.

Symptoms of food poisoning include stomach cramps, diarrhea, and vomiting, and can last from four to seven days. If listeria gets into the bloodstream, it can lead to meningitis, a life-threatening bacterial infection. Up to 20% of people with compromised immune systems die from food poisoning.

How can you be eco-friendly and keep your groceries safe? For starters, use the plastic bags in the produce section to protect your fruits and veggies. Also put meat and poultry packages in plastic bags to contain any juices that might leak. Keep produce separate from meats and poultry in your grocery cart. When you're checking out, have two totes handy: one for fruits and veggies and the other for uncooked meat and poultry. The Academy of Nutrition and Dietetics also has these guidelines:

  • Wash totes frequently, either in the washing machine or by hand with hot, soapy water.
  • Keep areas where you place the totes, such as kitchen counters, clean. To kill the bacteria on counters, spray the surface with an antimicrobial cleaner, such as a commercial cleanser or diluted bleach (½ teaspoon bleach in 1 quart water). Wipe the surface clean with a paper towel.
  • Store totes in a clean, dry place, and avoid leaving empty totes in the trunk of your car.

Food Poisoning

When food starts to rot it develops bacteria, breeds viruses, and may be infested with parasites. These or the toxins they produce may cause food poisoning. Care in putting away leftovers and tossing out questionable food will pro...

tect you. Some of the bacteria can be quite dangerous, including salmonella and E. coli. Several years ago, e coli infections traced to improperly cleaned lettuce resulted in severe illness and forced the closure of the Chi-Chi's restaurant chain.
