Diluted Weed Killer on Wood

I was spraying for weeds yesterday, all while being very mindful of the woodpile. Well while I was spraying a wind came up and the wood didn't get hit directly, but it did get a little bit of overspray. :doh::doh: It was Weed-B-Gone attached to my garden hose so it wasn't concentrated weed killer, it was diluted, but weed killer non the less. Is my wood okay to cook with?

I never thought to look for their MSDS!! :doh:

Thank you.
