The Center for Food Safety in Hong Kong said last Tuesday that a random¹ inspection² revealed that two out of five types of hairy crab³ samples are contaminated with cancer-causing chemicals.

香港食品安全中心上周二称，9月底进行的一项随机抽查显示，5种大闸蟹样本中有两种受到了致癌化学物质的污染。

The crab samples originated from two farms in Jiangsu on the Chinese mainland and have been found to exceed the safety level of dioxins and dioxin-like polychlorinated biphenyls (DL-PCBs).

这些大闸蟹样本来自内地江苏省的两家养殖场，相关部门发现其二恶英和类二恶英多氯联苯含量均超过安全标准。

Test results of the inspection in late September showed that the two types of crabs⁴ contained 11.7 picograms and 40.3 picograms of dioxin per gram of weight, respectively, much higher than the prescribed level of 6.5 picograms.

检验结果显示，每克这两种大闸蟹样本的二恶英含量分别为11.7皮克和40.3皮克，远高于6.5皮克的规定值。

The International Agency for Research on Cancer has classified dioxins and DL-PCBs as human carcinogens. Long-term intake⁵ will cause damage to immune systems, reproductive functioning, endocrine and developing nervous systems.

国际癌症研究机构已将二恶英和类二恶英多氯联苯列为人体致癌物，长期摄入会对免疫系统、生殖功能、内分泌系统及发育中的神经系统造成损害。

Authorities have ordered retailers⁶ to stop selling the crabs from the two farms, but it is not clear how many of the affected⁷ crabs had already been sold.

目前，相关部门已要求零售商停售产自这两家养殖场的大闸蟹。但是现在还不清楚有多少受到影响的螃蟹已经被出售了。

It has been reported that these two farms have supplied 80% of the hairy crabs in Hong Kong market.

据报道，香港市场80%的大闸蟹都是由这两家养殖场供应。
