SACRAMENTO, Calif. (AP) — California pesticide regulators have fined six companies they say ignored warnings and repeatedly sold imported fruits and vegetables that contained illegal pesticide residues. The Department of Pesticide Regulations says Tuesday the companies based in Los Angeles and San Mateo counties imported the tainted produce from Thailand, Taiwan, China and Mexico and predominantly sold it to ethnic minorities. The department says the produce sold includes lychee, longan, burdock root, ginger, taro root, fragant pear, cactus leaves, cactus pears, purslane and squash.
