Do pesticide residues persist on bush tomatoes? Apparently not — or at least not much, according to a new study. When fruit was treated directly, then washed and brushed during normal postharvest handling, most — if not all — chemical residues were reduced by 50 to 95%. Extensive sampling at commercial packing facilities showed no detectable residues.
