Ok, so having a little bit of a freak out and could do with some reassurance!
Today, I had a tuna melt panini in Costa coffee. Obviously it was heated, but it wasn't hot all the way through.
I've just read that in some countries the advice is to avoid pre-packaged sandwiches because of the risk of listeria. So wishing I hadn't eaten it as am getting myself worried. Pre-packaged sandwiches aren't on the nhs list of foods to avoid though.
Help to reassure me please :( xx
