Sorry to hear about this

You'll be able to tell what may / may not have been affected within the next few days, as you'll see the yellowing that is a symptom of weedkiller damage (as you've noticed on the goosegogs). No yellowing and the crops will be fine.
I'd do two things. Firstly, if you're sure of what you've been told by your other neighbour i.e. that it is weedkiller damage, and that it was caused by the first neighbour, then I'd mention it to the powers that be, as beansticks said. I wouldn't get too heated about it this time round, but just making sure it's been noted at this stage and so that if it happens again greater action can be taken.
Secondly, I would speak to the person and point out the damage which has been done, and ask them to ensure they only spray on a windless day and not near your plot in any event. If they are dismissive, also report that.
As for eating anything, I'm fairly robust and wouldn't bother worrying, but if you're organic then you may prefer not to eat the goosegogs if the fruit looks affected.
NB, someone else had a similar thing happen to them recently, albeit deliberate action by a well-meaning neighbour. It may have been Teen76 in Chatting on the Plot. A range of responses and advice were offered, from mild-mannered 'have words' to 'get him back'. One useful post pointed out that he still had to garden alongside the neighbour, for the time being at least, and that a less assertive / aggressive approach in the first instance might be a better tactic.
