This was already considered in designing spacecraft to go to Mars.
The astronomers calculated rare asteriodal impacts on Earth had
already resulted in several tons of viable material being dropped
on Mars.
So, not to worry. Mars is already contaminated. Europa too, I'll bet.
Maybe Titan is relatively clean, but nothing closer.
