Hi Kari,
I've been looking around my place for an old Safe-Guard tube but wouldn't you know I can't find one. It seems to me that it says that there is a 14 day withdrawal period for using this on lactating animals but don't quote me on that. What I did find in the meantime is the FDA Fact Sheet on Safe-Guard. It mentions 8 days withdrawal for slaughter cattle. I think I would wait 14 days though:
