Bordeaux mix

I sprayed my toms (outdoor cherry & plum) before we went away 2 weeks ago. Some of the fruit is now ready to pick & eat but is splattered with the mix, goes a lovely blue colour when washed off. There is no info on the pack about intervals between spraying and eating, other than to spray at 3 week intervals, does anyone know when/if they are safe to eat?

 Thanks Aunt Sal, I wouldn't normally use it, but had to go away and the weather forecast didn't look good wrt to blight. Dithane is no longer available, so if Bordeaux mix goes there won't be much left, which may or may not be a good thing depending on your point of view.

this is Bayer's replacement for Dithane

it uses copper oxychloride, Bordeaux mix is copper sulphate.
The RHS doesn't seem to think it's as nasty as copper sulphate as they post no warnings
