Why would a cut onion or garlic "attract" more bacteria than anything else with a cut wet surface? Is the fridge is swarming with onion-seeking bacteria frantically rushing round looking for a fix? Covered and used as soon as possible it will be fine. You wouldn't keep it i nthe fridge uncovered anyway, transferring the smell to the butter (which should also be covered . . . .)
How on earth did our parents and grandparents survive to produce us with all these health hazards that keep appearing from nowhere.
