There are poisonous plants, so it's imperative that you get a good book as a field guide and do some studying before heading out. Additionally, personal advice from a well seasoned forager can't be emphasized enough.
While this should go without saying, it is best to avoid foraging from roadside or pesticide and herbicide sprayed fields. Wherever there may be chemical runoffs or other pollutants, those areas are to be avoided. And, if necessary, make sure you have permission to be on the property.
Being a good steward is key. Norris suggests not taking all of a morel mushroom, for example, and leaving part of the stem in the ground so spores can continue to propagate. Don't leave any trash in your wake. And get permission from private property owners.
There may be some parts of plants, like wild rhubarb, where the leaves are inedible. Or mushrooms that should be cooked and not eaten raw. Each plant has a particular way to be prepared. This takes time to know and it's an important skill to develop.
Your digestive system might need time to adapt to these new foods, and you'll want to rule out any potential allergic reactions. And, of course, never eat a plant unless you're exactly sure what it is.
While there are many enlightened individuals who understand how to forage in grocery store aisles for organic and non-GMO foods, very few folks have taken the hours necessary to learn foraging techniques. Why? We have been perfectly spoiled by a food abundance. And even for folks pondering the idea of eating from the great outdoors, there are underlying fears about the dangers of foraging, including dying from poisonous plants that might just look exactly like the non poisonous one. Famed forager and author Samuel Thayer calls this the "Poison Plant Fable," which he states was used in the movie "In The Wild," a story of Chris McCandless's search for truth in the backwoods of Alaska where he died, ostensibly from eating the wrong plant. Thayer, who convincingly writes that McCandless death was from starvation and not a poisonous plant, says this disinformation is "ignorant fear mongering" and a "disservice to everybody." Mr. Thayer has been foraging since he was a child. But for those who are just beginning, it is wise to be curious, and also cautious as you hone your foraging technique.
