Fruits and vegetables are highly nutritious but also highly perishable, leading them to often be contaminated with toxic pesticides. Testing found that 98% of apples and over 95% of celery contained at least one pesticide residue. Common fruits and vegetables like strawberries, spinach, and grapes frequently test positive for pesticides. Pesticides are designed to kill and are generally not good for human consumption. Reducing exposure by peeling produce and washing hands and surfaces thoroughly can help lower health risks from pesticide residues.
