Minimizing the risk of E.coliHow consumers can reduce the risk of infection in their home

TAMPA, Fla. (Dec. 14, 2015) – Following the illness of 19 people in seven states from the bacteria Escherichia coli, or E. coli, retailers across the nation are pulling products containing celery from their shelves because of potential contamination. At the same time, more than 47 people from nine states have been sickened after eating at Chipotle Mexican Grill, where a recent E. coli outbreak occurred.

With some strains of E. coli causing symptoms such as diarrhea, urinary tract infections and pneumonia, it’s important for consumers to prevent outbreaks in homes and business, especially if they suspect they’ve bought a contaminated product or brought home contaminated take-out food.

“When someone buys a contaminated food and takes it home or at their business, every surface that is has touched is at risk of carrying that bacteria, especially in or around food preparation,” said Rajiv Sahay, Ph. D., FIAS, CIAQP, Director of Laboratory Services at Environmental Diagnostics Laboratory (EDLab), a division of Pure Air Control Services. “Even after the product has been thrown away, the kitchen counter / break room area may still test positive for E. coli.”

E.coli is a diverse group of bacteria that can be found in the intestines of humans and other warm-blooded animals, as well as in the environment. Although several strains of E. coli are harmless to humans, others can cause illness when outside the intestinal tract, including E. coli O157:H7, which was found to be the cause of recent illnesses.

E,coli can be transmitted two ways – either by consuming affected food or water, or making physical contact with an infected surface, person or animal.

To prevent an outbreak of E. coli from spreading in the home, it’s important to practice common hygiene practices. Thoroughly clean all fruits and vegetables, which can be carriers of the bacteria, and properly sanitize all surfaces that have come in contact with raw meat. Refrigerators should also be set to 40° F or cooler and store hot food above 140°F or above to prevent bacteria from multiplying.

For those who have purchased food items that may be contaminated, testing of the water and/or household surfaces for E. coli may be warranted. Do-it-yourself, at-home E. coli test kits are available through This can identify E. coli bacteria present in the home and provide consumers with concentration levels for the bacteria.

“Armed with this information, homeowners and business owners can determine whether a thorough sanitation of the affected area is needed,” said Dr. Sahay. “It is a small price to pay for peace of mind.”
