If I'm not mistaken, wild Muk and wild Garbodor have a 50% chance of holding Black Sludge in the wild. This is somewhat annoying considering that the only place they can be captured is Safari Zone 5.

It depends on the item I suppose. For instance, a wild Numel would be guaranteed to be holding a Rawst Berry while a Pikachu would only have a 5% chance of holding a Light Ball. Lead with a Pokemon with the Compound Eyes ability to increase the odds of encountering a Pokemon with an item in the wild.
