Core Viewpoint - A recent comparative test of fruit and vegetable cleaning machines revealed safety hazards and inconsistent pesticide residue removal effectiveness among popular products in the market [1][3]. Group 1: Test Results - The test involved 10 popular products purchased from e-commerce platforms, with prices ranging from 200 yuan to 3,800 yuan, covering two main technology types: ultrasonic and hydroxyl water ion [3]. - Two products, "Xianjin" and "Guge," failed to meet national safety standards, posing electric shock risks and were rated as "not rated" [3]. - All tested samples achieved a 99.9% removal rate for E. coli, indicating strong performance in bacterial purification [3]. Group 2: Pesticide Residue Removal - The products showed good degradation rates for certain organophosphate pesticides, with removal rates generally exceeding 95% for dichlorvos, while lower removal rates were observed for chlorpyrifos and cypermethrin [3][5]. - Only three products, "Huiren," "Lanliqing," and "Shengdini," received an "excellent" rating based on comprehensive evaluations [5]. Group 3: Consumer Guidance - The consumer protection committees advised consumers to purchase from legitimate channels and look for national safety certifications, cautioning against exaggerated claims like "complete sterilization" [5]. - It is recommended to combine the use of cleaning machines with traditional methods such as soaking and blanching to maximize food safety [5].
