So, CDC has issued an advisory requesting not to ear frozen vegetables until the issue has been resolved. Meanwhile please avoid eating frozen vegetables (at home or restaurants).
As we read information that's out there, seems very scary and seems like we all must have listeria. I did see a lot of patients with gastroenteritis a few week ago when many had presented with vomiting and diarrhea and felt very sick (sicker than they may have felt with the "24 hour bug".
Anyways, it is more significant for pregnant women, people over the age of 65 or if one has significant chronic illnesses or undergoing treatment (or on medications for) for cancer, HIV, Hepatits or certain rheumatological illnesses... If you are one of them AND having fevers, weakness, fatigue and gastrointestinal symptoms, then you should see your doctor and consider getting appropriate blood work done.
Listeriosis is not a major concern for otherwise healthy people and there is no need to panic. See your doctor only if you have symptoms.
...and I am sorry, you still have to eat your vegetables.. only buy them fresh and wash them well before cooking. If you are eating out, just make sure those places use only fresh vegetables and not frozen vegetables.
Below is some more information from cdc.gov:
Listeriosis is a life-threatening infection caused by eating food contaminated with the bacterium (germ) Listeria monocytogenes. The disease primarily affects pregnant women and their newborns, adults older than 65, and people with immune systems weakened by cancer, cancer treatments, or other serious conditions (like diabetes, kidney failure, liver disease, and HIV). Rarely, people without these risk factors are affected.
A person with listeriosis usually has fever and muscle aches, sometimes preceded by diarrhea or other gastrointestinal symptoms. Almost everyone who is diagnosed with listeriosis has invasive infection, meaning the bacteria spread from their intestines to the blood, causing bloodstream infection, or to the central nervous system, causing meningitis. Although people can sometimes develop listeriosis up to 2 months after eating contaminated food, symptoms usually start within several days. Listeriosis is treated with antibiotics.
The symptoms vary with the infected person:
Adults older than 65 and people with weakened immune systems: Symptoms can include fever, muscle aches, headache, stiff neck, confusion, loss of balance, and convulsions.
Pregnant women: Pregnant women typically experience only fever and other non-specific symptoms like chills and headache. However, infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
Healthy people. Healthy people rarely develop invasive listeriosis. However, people exposed to a very large dose of Listeria bacteria can develop a non-invasive illness (meaning the bacteria do not spread into their bloodstream or other sites) with diarrhea and fever.
