What is listeria?
Listeria is a bacterium that causes listeriosis. Cases of foodborne illness from listeria are rare, but can involve serious symptoms and even death in certain groups of people.
Some people are more vulnerable to listeria infections, including those over 65 years of age, pregnant women and their unborn babies, babies less than one month old and people with weakened immune systems.
Symptoms caused by this organism can be similar to flu and include high temperature, muscle ache or pain, chills, feeling or being sick and diarrhoea.
