1. Listeria in Mangoes
By the Knights of the Round
Tomato

2. What is Listeria and what can it
do to humans?
Listeria is a bacterial genus. It can cause a serious but
rare disease in humans called listeriosis. The most
common symptoms are fever, muscle aches, and
vomiting. It usually infects pregnant women,
newborns, adults with weakened immune systems,
and the elderly. Listeria can be found in soil, so it
can infect vegetables. Animals can carry Listeria. It
can be found in fruits, uncooked meat, and milk.

3. So, how are you going to solve
this?
Well, we found that a mix of two
chemicals can kill Listeria. One is
alcohol, and another is Quaternary
Ammonium. Creating a wash or rinse
of these chemicals will have a 99.9%
chance of killing all the Listeria. Also,
once consumers buy the product,
keeping in under forty degrees can
prevent further growth of bacteria

4. Has an event like this
happened?
Yes. In early September, 2011, this was a
Listeria outbreak in cantaloupes. As of
November 3, 2011, twenty nine people
have been confirmed dead in
outbreaks with cantaloupes from
Jensen Farms in Colorado.
