I agree w/ Charlotte. Even if there was chicken juice in the grease it would have been so hot that I don't think any salmonella could have lived, now if you'd cut the chicken on the same plate as the brownies or plain chicken juice (w/o the heat) was put on it then there'd be cause for concern. But really I don't think any juice got on it at all, just grease. Plus it couldn't have been all that much that got on it or you would have tasted the grease on the brownies. Hope this helps. I hate stuff like this because us emets worry about it until the "safe time" has passed. Try not to do that but I know it's hard.
