Can vegetables carry Listeria?
Listeria bacteria can be found in soil, water and animal feces. People can get infected by eating the following: Raw vegetables that have been contaminated from the soil or from contaminated manure used as fertilizer. Contaminated meat.
How common is Listeria in frozen vegetables?
They say that the risks of contracting listeriosis in frozen vegetables is lower than the risk associated with smoked fish, sausages, pate, and soft cheeses. Processors often blanch vegetables before freezing them to set the color and texture, and this step helps destroy pathogens on the food.
Can Listeria survive being frozen?
Consumers at high risk for contracting listeriosis (e.g. pregnant women and the elderly) should reheat deli meats immediately before consumption. FREEZING – Listeria is not killed by freezing. Growth is arrested altogether, but normal growth will be resumed after thawing.
Can frozen vegetables have bacteria?
Frozen produce is picked at its ripest point and packaged quickly after to maintain freshness. Freezing food inactivates bacteria that could cause a foodborne illness. When frozen produce is thawed, however, bacteria again grow at a normal rate. Use thawed foods within three days.
What vegetables have Listeria?
Vegetables that grow in the soil, like beets, carrots, and potatoes can come in contact with listeria in the soil, as can those that grow on low-lying vines like zucchini and other types of squash. But please don’t let fear lead you to avoid veggies, which are healthiest foods in your diet.
What foods are most likely to contain Listeria?
Outbreaks of Listeria infections in the 1990s were primarily linked to deli meats and hot dogs. Now, Listeria outbreaks are often linked to dairy products and produce. Investigators have traced recent outbreaks to soft cheeses, celery, sprouts, cantaloupe, and ice cream.

Keep your refrigerator at 40 degrees F or lower and the freezer at 0 degrees F or lower.
Can you get sick from undercooked frozen vegetables?

For the very young, the elderly, and the immune-compromised listeriosis can result in death.
How do you check for Listeria?
Listeriosis is usually diagnosed when a bacterial culture (a type of laboratory test) grows Listeria from a body tissue or fluid, such as blood, spinal fluid, or the placenta.
How common is it to get Listeria?
An estimated 1,600 people get listeriosis each year, and about 260 die. The infection is most likely to sicken pregnant women and their newborns, adults aged 65 or older, and people with weakened immune systems. Pregnant women are 10 times more likely than other people to get a Listeria infection.
