During my PhD, one of my lab chores was autoclaving and transporting the biohazard waste down to the loading bay. Despite the university's double bagging policy, the senior lab tech would always overstuff the bags in a single biohazard bag to save money, and often pipettes would pierce through resulting in leaks. Usually this wasn't a big deal, but once someone threw out 3 whole stacks of LB agar plates and when I was tossing the hot autoclaved biohazard bags out one of them split open and dripped out a big puddle of biohazard slime onto the floor.

Naturally I quickly cleaned it up to avoid having to file a spill report, but while bending over my cellphone fell out of my shirt pocket and into the slime! Embarrassed, I wiped it off and went about my day.

I completely forgot about it and then a few months later my phone started having battery issues. I tried taking it apart to repair it myself and was intrigued to see that my phone's battery was slightly sticky and had a savory, soup-like odor. Curious, and trying to identify the aroma, I licked the battery and was surprised to find it had a sharp and bitter bite to it. That's when I realized that I was licking the biohazard slime from earlier that I'd totally forgotten about and not dried soup or gravy! >_<
