okay finally i get to use the knowledge from my job here.
scrub the plywood thoroughly with a wire brush or sand it to remove all visible growth and to at least a foot beyond the visible growth's edges. make sure you don't miss the edges. if the mildew is on both outside surfaces it's between the plies too, and that means you have to replace the wood. hate to be a spoilsport, but i work in mold/mildew restoration.
bleach sprays kill what's on there but, they don't prevent recurrence and the first infestation has already partly 'digested' your wood, leaving it ready for the next wave to move in.
once it's clean you should treat it with KILZ (two coats) and paint. The thing is, once it's mildewed or grown mold, you have to keep it as dry as a powderhouse to prevent regrowth.
all molds are known to be allergens. the effects vary depending on a person's sensitivity and the intensity and length of the exposure. some molds also produce poisonous substances called mycotoxins, and while usually the biggest threat these pose is by eating them, breathing them is not so good either.
a tear is a very small space inside and ventilation in many if not most is ... well, less than optimal, okay? ... so it really does pay to err on the side of caution.
sorry to be such a downer.
