I hope someone or an animal is not eating yew needles. If so, call the poison control hotline at https://www.poison.org/ or 1-800-222-1222.
Any amount eaten is a medical or vet emergency. As little as a mouthful can kill a 1,000 pound animal in only a few minutes.
50 grams is about 2 ounces or one tenth of a pound which isn't very much. If you have a measuring cup in the kitchen it has ounces on it.
