I am LTTTC AML and still eat fairly freely... I am sure that this history makes an impact, but it's not the sole factor. I simply don't believe the risk is big.
Agreed, I also love Artechim's Listeria Hysteria comment, have used it myself in the past, its very true in my mind. I totally understand and respect why some pg woman would rather err on the side of caution though. However I have always embraced my pregnancies and I guess what I see as a bit of a media/info beat up isn't a risk or something I am prepared to worry about or fear.
