What do you do with all the liquid in the package?  I open the package and drain it… in the sink. When I rinse vegetables, which I think people know to do, it’s in the sink. And when all done, I clean and dry the sink. 

So speaking to bacteria in your sink, you are supposed to clean the sink (and countertops) after cooking.

I get sooooooo grossed out that some people don't wash their sinks. There's a woman on IG that does cleaning videos and she gets ridiculed whenever she does a sink-washing video. If these people did a bacteria swab of the top rim of their sink they'd probably die inside.
