Legionella in home refrigerator?

My refrigerator at home has a clogged freezer drain. As such, a leak started from the freezer into the fridge below. We put a cake pan which we empty regularly about 1 time per week. However my 3 year old ended up drinking some out of that tray because we were out of water bottles and she didn’t tell us like she usually does. Is it possible to contract Legionella from your home refrigerator? Should my wife or I be worried about exposure as well?

I would guess that little risk, if any, would occur from drinking water from that tray. If your health seems okay now, I would surmise no harm has been done from drinking this water. To be certain, consult your physician.
