lol - i would ask your doctor for some information and statistics.
I just remember my dr with #1 said to me that listeria got such a big awareness in australia because a politicians wife a few years back had a MC due to it.

From what i can remember the biggest threat is between 2-3 trimesters.

I wouldnt stress as the stress is definately not good for you or the baby this early on. Just be mindful and perhaps look up some nice recipes you can cook and make yourself instead of buying out if it makes you feel better

I know with #2 i was not half as strict as i was with #1 (ie cold meats, cheeses, caffiene etc) and i had to perfectly healthy babies.
