I ordered pizza with anchovies and they came uncooked on top- I googled and found a website saying tinned anchovies are fine uncooked due to salt, so ate them, but have just remembered the nhs says not to eat cured fish and I don't know if tinned anchovies count? I'm 31 weeks and have been v careful so far, every time I've eaten anchovies on pizza it's been cooked but now I'm having a mini panic about listeria- can anyone reassure me?
