MIL made me a salad last night (which by the way was delicious ) and afterwoods mentioned that it was made from hydroponic lettuce (you know, the one with the roots still attached.) She had washed it when she bought it, but had then put it back in the same plastic bag she bought it in - and didnt rewash before serving it to me.... If I hadnt of known, I wouldnt be worried - but now that I know.....

SHould I be worried about exposure to listeria??

Thanks in advance.... I swear I am not a nutcase - this eating business is just doing my head in!! *chants to herself* "6 weeks to go, 6 weeks to go"....
