Is there a risk of eating poisonous berries?
According to How to Survive in the Woods for 3 Days: “white and yellow berries are poisonous 90% of the time, blue and black berries are good to eat 90% of the time (however, deadly nightshade berries [see photo to the right] are dark blue or black and they taste sweet, but a couple can kill you fairly quickly), and red berries are a 50/50 shot. Aggregate berries (bumpy ones like raspberries, strawberries, etc.) are almost 100% good to eat. The only exception to that rule is a white berry that grows only in Alaska.” Mulberries are aggregate berries. As for Saskatoon berries, Steve Brill (see link below) says: “There are no poisonous look-alikes, since no poisonous berry has a crown.” You may wish to consult an accurate, detailed field guide prior to consuming berries in the wild. Or check with someone who knows berries.
