Peanme you scared the youknowwhat out of me by putting "Final Update" !

OMG, sorry, I never thought it would be interpreted that way!

Never meant to scare anyone - just figured it would be the last time I'd have to update!
I did throw everything away (even things like cantaloupe that my mother had sliced), and went on major sanitation patrol here in the household as I didn't want anyone else to get it. I cleaned bathrooms twice a day with Lysol wipes once we were home with DD. I've always taught the kids good hygeine methods, but in the hospital and after arriving home I went over it again and again to be sure. DD understands about germ transmission so she's been very good - I'm observing.
Same with my mother's. We have an in law apt. I actually tried to hire a cleaning company to come in and deep clean as it needed it anyway and I was just too exhausted to do it. My plan was to do the bathrooms and kitchen "first" myself anyway

and I was honest about having a food borne illness in the house because it only felt right. Nobody wanted the job so DH and I donned gloves and did it ourselves. (Was thinking that might make a good debate thread, lol.)
As for whether and where to buy hamburger in the future, I've been thinking about it a lot. I think, and I'm going to bold this, THE KEY TO NOT GETTING THIS ILLNESS IS TO COOK ALL HAMBURGER TO > 160 DEGREES, regardless of where you buy it.
Someone IRL suggested buying steak and having it ground into hamburger, but we know from articles like the NY Times one that E Coli is on the outside of most beef. Cooking muscle meat that has it on the outside kills off the bacteria. If you bought a steak that may have E Coli on the outside and grind it into hamburger, you're back at square one, so I don't know that that would be the answer, whereas cooking temp is always a factor.
With all that said, I'm still going to do some inquiring at some of the regular places I shop to see what I can learn about it. I might look into buying at smaller shops that use local beef as well. (To be honest, it kind of grosses me out just thinking about it.

I know I said before that DD had mentioned wanting chili at one point, but right now if you mention hamburger, she gags.)
