Cheese Ingredient?

I don't generally purchase foods that are too "processed" but I make an exception when it comes to shredded cheese. I've been able to get it cheaply, and I figure the extra expense is more than made up on the band-aids I'm not using when I shred my knuckles.

Yesterday my More-Health-Conscious-Than-Me Neighbor asked if I knew anything about an ingredient they're putting in shredded cheeses: natamycin. According to the package of cheese in my refrigerator, it's a mold inhibitor.

I didn't mind when they tossed a little cornstarch in the bag of cheese to prevent the shreds from clumping, but I'm not feeling too good about this.

Guess it's time to re-stock that kitchen band-aid box.
