Cluster berries, from raspberries to pineapples, are never poisonous. Avoid berries that resemble blueberries or currants unless you're able to identify the plant: we grew up with blueberries and know the leaves, but we avoid anything currant-like because we'd have no idea if they're actually, say, chokeberries. Avoid anything that looks like baneberries.

Here in Maine, we forage for raspberries, blackberries, wild strawberries, and (mostly low bush) blueberries, but don't risk others.
