“Signs of listeriosis include flu-like symptoms such as fever, muscle aches, nausea and diarrhoea that can sometimes lead to septicemia, meningitis and in some cases, miscarriage in pregnant women,” Dr McAnulty said.
Investigations into listeriosis are complex as it can be difficult to identify the source. Symptoms of illness can take up to 70 days to appear.
Healthy people usually show only mild symptoms. However, in people at risk, early symptoms of listeria infection include fever, headache, tiredness and aches and pains.
