When tempeh goes bad, very bad

Along with the awesome hummus I made for dinner yesterday, I also made a tempeh, couscous, chard combination.

When I opened the package of tempeh, I thought the color looked a bit grey (but tempeh is normally pretty grayish, isn't it?). And since I don't have that much experience with tempeh and it didn't smell and didn't taste bad, I didn't give it a second thought.

I woke up around 3:30 a.m. with my stomach in what felt like very painful KNOTS. I went back and forth to the bathroom at least once an hour for the next five hours and eventually threw up. All the while my stomach was killing me.

I asked Jody to hang out at home for a bit when he got up for work because I didn't know how long I'd feel that way and I really needed some rest. He went to the store and got me some ginger ale which I could barely sip. Ugh. The stomach cramping was awful.

I finally started feeling better around 9 a.m. and slept another two hours.

The rest of the day I've been fine. A little pale, but pretty much back to normal stomach-wise.

I thought that Ava had avoided it since she hardly ate any of the tempeh yesterday, but instead was intent on devouring the hummus. ;)

Well, all was fine until about two hours ago, when she threw up all over the both of us. She's since thrown up about 4 more times - twice dousing our clothes. I have a
feeling this could be a long night.

Jody has so far escaped unscathed, though he has a much heartier constitution than I do. Lucky bastard. ;)

By the way, I checked out the tempeh, since we had leftovers in the fridge, and upon closer inspection, it appears there may have been mold starting to grow on it! *gag* Uh, no wonder I got sick. Anyway, the expiration date on the package was Feb. 5 so I wouldn't have even thought it possible that it would be bad. Guess I will be inspecting my tempeh a lot more closely (or avoiding it altogether) from now on.

Anyone else have problems with tempeh going bad?

Updated at 11:05 p.m. to add: I can't even count the number of times she's thrown up now. Ugh. The good thing (I guess) is that as soon as she's done puking she seems to be feeling absolutely fine again - running around like her crazy ol' self. So I keep thinking she's over it, but then she pukes again. *sigh* Hopefully this won't last all night. (Crossing my fingers)
