Query: Toxic Chemicals

The Macgregor Rubber Soccer Ball, size 5, came in the mail today and along with the ball was a warning label: "These products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm." The inclusion of this warning is part of Cali's "proposition 65," and is not required by US Federal law. That may be the reason the warning is not found anywhere in the Amazon description. I got the ball for me and my 2-year-old to play around with, but I don't feel comfortable using it now. I'm going to return it. Otherwise, if the whole chemical deal doesn't bother you, the ball seems fine to play with.
