Cross contamination

So, I have been storing all of my expressed breast milk in the top portion of our freezer. Today I noticed that there was something wrapped in foil tucked away right by the breast milk. I have no idea how long it was there. I had my DH look at it and it was frozen chicken. I definitely did not put it there and I don't know how I didn't notice it before! My question is, is there any chance that the chicken somehow contaminated the breast milk? It was frozen, and the breast milk is stored in sealed in storage bags, so I think it's okay, but I need some reassurance! (Also, I threw out the chicken since I had no idea when it was from)
