The U.S. Food and Drug Administration (FDA) issued a nationwide alert
warning consumers about the risk of contacting Salmonella from certain varieties of tomatoes on June 9.
Epidemiologist Casey Barton Behravesh told CBS News in a June 4th
story that “the specific type and source of tomatoes is under investigation.”
While the investigation is played out, officials are warning food operators and
consumers to avoid raw red plum, red Roma, and round red tomatoes. Dishes
containing raw tomatoes, such as salsa, guacamole, and pico de gallo might also
be contaminated.
    The outbreak likely originated in New Mexico and Texas, with reports of Salmonella poisoning caused by the
serotype Saintpaul surfacing in mid-April. New Mexico and Texas have reported
the most cases, with 39 and 56 illnesses documented, respectively. Other states
reporting incidences of the Saintpaul strain include: Washington, Oregon,
California, Utah, Idaho, Arizona, Colorado, Connecticut, Illinois, Indiana,
Kansas, Michigan, Virginia, Wisconsin, and Oklahoma. The wide range of
infections leads authorities to believe that the contaminated tomatoes were shipped
throughout much of the U.S.  
    Cherry, grape tomatoes, tomatoes sold with the vine still attached, and
homegrown tomatoes are not likely to be contaminated with Salmonella and are fine to eat, according to officials. Red plum,
red Roma, and round red tomatoes grown in areas not implicated in the outbreak
are also presumed safe to consume. A complete list of non-affected regions can
be found at 
    Salmonella, which lives in humans’
intestinal tracts, causes fever, diarrhea, and abdominal cramps. The illness
usually lasts four to seven days. According to the Centers for Disease Control
and Prevention (CDC), there have been 167 reported cases in 17 states.
Twenty-three infected people have been hospitalized, and Fox News reports that Salmonella was a contributing factor in
the death of a cancer patient in Texas. The FDA, according to CNN, is using
“traceback” investigations to isolate the origin of the contaminated product.
Investigators are studying the similarities in the reported illnesses and
working backward to identify the source.
    Restaurants are rushing to pull potentially affected tomatoes from their
locations in order to protect customers. Major chains taking the red plum, red
Roma, and round red tomatoes off their menu include McDonald’s; Burger King
Corp.; Yum Brands Inc.; Red Lobster and Olive Garden; Chipotle Mexican Grill
Inc.; Souplantation; Sweet Tomatoes; Jack-In-The-Box; and Daphne’s Greek Cafe.
Operators are still serving other varieties of tomatoes, such as grape
    Steps to help avoid contracting Salmonella from tomatoes include washing the tomatoes and cooking
them at 145 degrees for at least 15 seconds.
