my paranoidometer has gone into overdrive...Im 11+5 and its been a difficult pregnancy to say the least..Ive got a sub chorionic haemotoma and my last two pregs ended in late miscarriage naturally Im a little anxious (putting it mildly)...Ive had horrific sickness so DH has been doing the cooking although Im not really eating..he brought me a plate of potatoes with some pre packed salad on top of the potatoes..and I noticed that the salad was completely purple!..asked DH to check the use by date and it was 4 days past!..pushed it to one side and just nibbled the potatoes..then panicked that the salad had contaminated my potatoes with listeria..DH doesnt see what the problem is as he washed it ..but Ive been googling and it says that food past its use by date is prime location for listeria..so am beside myself now with worry....someone talk some sense into me please?
