My stupid brother left a plate of meat in my room and I'm scared?

That retard has the habbit of when he comes to visit, he eats in my room. The idiot was apparently eating like a mexican plate of beef, potatoes, avocado, and sourcream! When I was going through my dirty clothes bin I found a bag. When I looked in it, I saw the plate of food gone bad, bad! It was full of mold and these little fly looking things. I didn't even want to open the bag further. Is there a possibility my clothes are infested with animals? Maggots or those fly thingies? What where they? I'm so disgusted! The bad thing is that I'm a complete neat freak. I don't think I can use those clothes again... and the laundry basket either... omg. I need clorox.
