Accidental MSMA Spray on my herbs ( mint , oregano, Sage)?

Hello & Good day Experts !

My back yard is basically a World Crab & Dallisgrass heaquarter :) so i decided to kill em off with some MSMA.

It was windy outside and I think I might it might have carried a smal bit of MSMA spray to a section my herbs ( mint , oregano, Sage).

So my question is are my herbs useless now since they might have some arsenic on them?

should i remove them all?

or just a section that i " I SUSPECT MIGHT" have some MSMA on them

what would be the side effects short term or long term?

PLEASE HELP!!!

If you are unsure of how much they were exposed to, you cannot eat them. They're done.
