Of course if there were berries on the plant when she sprayed, those are inedible. Roundup does not persist in the soil, but it is hard to know what, if any, residual damage happened within the plant. Since your plant survived the spray, it must not have gotten much or it would not have survived.

If you want to err on the side of caution, remove and replace the plant. It can be grown in the same place. The article below suggests, for perennial edibles, wait one growing season.
