My post started “Let’s suppose…” it was just a hypothetical mentioning a MIL, not something that actually happened to us.
We do defrost meat in the sink, because our bigger dogs could reach it if it was on the counter. No one would wash dishes with detergent if there was meat in the sink. Dishes get a quick rinse and are placed right into the appropriate dishwasher (except on Shabbos or Yuntif and we’d not be defrosting raw meat then).
But, thanks for your advice, anyway.
