Pesticide Reduction Efficacy from 47 Studies on Household Produce Washing Methods

47 peer-reviewed studies provide data on the effectiveness of household washing methods for reducing pesticide residues on 23 produce items. The dataset includes 1,100 individual reduction-efficacy data points for rinsing with tap water, soaking in tap water, baking soda solution, and vinegar/acetic acid. Dayna de Montagnac compiled this scoping review, last updated in April 2026.

Use Cases

• Compare the median reduction efficacy of different washing methods based on the reported 30.2% for rinsing, 33.7% for water soaking, 50.9% for baking soda, and 54.2% for vinegar.
• Analyze the range of pesticide reduction outcomes (0.0% to >99.0%) based on the collected data points for each method.
• Investigate factors impacting pesticide reduction based on the reported influence of pesticide physico-chemical properties, washing method, and produce characteristics.
• Assess the generalizability of laboratory findings to typical household use based on the described limitation of high solution concentrations in studies.

Strengths

• Data is derived from 47 peer-reviewed studies, suggesting a systematic evidence base.
• Includes 1,100 individual data points across four distinct washing methods.
• Covers 23 produce items and 79 pesticides, indicating breadth in the factors studied.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The high solution concentrations commonly studied may limit generalizability to typical household use, as noted in the description.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
