Core Viewpoint - The article discusses the safety of pesticide residues on fruits and provides methods to reduce these residues, emphasizing that most fruits purchased from legitimate sources do not exceed safety limits [1][5]. Group 1: Pesticide Residue Safety - Pesticide residues on fruits are not a health risk as long as they do not exceed safety limits [1]. - Most fruits bought from legitimate channels have pesticide residues that are within safe limits [5]. Group 2: Methods to Reduce Pesticide Residues - **Storage**: Allowing fruits like bananas, kiwis, and citrus to sit at room temperature for a few days can help degrade pesticide residues while the fruit ripens [2]. - **Water Washing**: Washing fruits with water can remove up to 70% of water-soluble pesticides, such as imidacloprid found in apples. Soaking soft fruits like mulberries and bayberries in water for about 10 minutes can effectively remove surface residues [3]. - **Peeling**: Although peeling fruits may result in some loss of nutrients, it is highly effective in removing pesticide residues, with up to 92% of certain lipid-soluble pesticides being eliminated [4].
