What are the symptoms of listeriosis?
Symptoms of listeriosis resemble those of the flu and may include fever, chills, headache, feeling unwell, muscle pain and diarrhoea. If the bacteria infect the nervous system or the blood, severe listeriosis can set in. Symptoms of severe listeriosis include stiff neck muscles, twitching, seizures, loss of physical coordination and confusion. In infants, symptoms can include loss of appetite or food refusal, jaundice, trouble breathing, shock, irritability, lack of energy, skin rash, and an upset stomach or vomiting.
