Zinc fumes can give you flu like symptoms, which can take 3 weeks to go. It is probably best to wear a good quality respirator and work in a well ventilated area. Zinc inclusion in the weld won't really happen as the zinc will burn off, but for the sake of your health it is better to sand it off, while wearing a mask as the dust is just as poisonous. A lot of heavy metals are cumulative poisons as the body can't get rid of them. Fortunately zinc can be dealt with by the body.
Have fun welding !
