Following reports of ten cases of possible organophosphate pesticide poisoning in florists exposed to pesticide residues on cut flowers, we conducted a prospective random-sample survey to determine residual pesticide levels on flowers imported into the United States via Miami, Florida. A sample of all flowers imported into Miami on three days in January 1977 showed that 18 (17.7 per cent) of 105 lots contained pesticide residue levels greater than 5 ppm, and that three lots had levels greater than 400 ppm. Azodrin (monocrotophos) was the most important contaminant with levels of 7.7--4,750 ppm detected in nine lots. We examined 20 quarantine workers in Miami and 12 commercial florists exposed to contaminated flowers. Occasional nonspecific symptoms compatible with possible organophosphate exposure were noted, but we found no abnormalities in plasma or red blood cell cholinesterase levels. This study documents a previously unrecognized potential source of occupational pesticide exposure and suggests that safety standards should be set for residue levels on cut flowers.
在有报告称接触切花上农药残留的花店出现10例可能的有机磷农药中毒病例后，我们进行了一项前瞻性随机抽样调查，以确定经佛罗里达州迈阿密进口到美国的花卉上的农药残留水平。1977年1月三天内所有进口到迈阿密的花卉样本显示，105批中有18批（17.7%）的农药残留水平高于5 ppm，有三批的残留水平高于400 ppm。久效磷是最重要的污染物，在9批花卉中检测到的含量为7.7 - 4750 ppm。我们检查了迈阿密的20名检疫工作人员和12名接触受污染花卉的商业花店员工。发现了偶尔出现的与可能的有机磷接触相符的非特异性症状，但我们未发现血浆或红细胞胆碱酯酶水平有异常。本研究记录了一个此前未被认识到的职业性农药接触潜在来源，并建议应为切花的残留水平制定安全标准。
