Hi Stevie,

Here is some info I found re: this. Hope it helps.

Listeriosis can be transferred to the foetus and at worst can cause miscarriage, stillbirth or premature birth. Sometimes listeriosis has no symptoms, however, it may manifest as flu-like symptoms such as fever, headache, vomiting and diarrhoea or more serious symptoms such as meningitis or blood poisoning.

Listeria grows in the fridge. Do not eat foods that have been stored in the fridge for more than 12 hours. In other words, avoid leftovers and eat only freshly cooked or prepared food and avoid foods that are past their use-by date. If you are in doubt, throw it out.

Avoid high-risk foods including:


Pate
Smoked seafood

Soft or gourmet cheeses such as ricotta, camembert, cottage, blue vein, danish blue, stilton
Unpasteurised cheeses
Soft serve ice-cream
Cold cooked chicken
Cold meats

Store bought salads
Salads prepared more than 12 hours ago

Raw seafood including sashimi, sushi and oysters
