"[The] transport of livestock by sea over long periods"—and, remember, it takes about 17 days to get from New Zealand to China on a boat for these stock—"is a complex and challenging exercise requiring thorough planning and diligent execution [in] all stages to ensure adequate animal welfare results. The trade is difficult to regulate, given it spans jurisdictions and the high seas and involves a myriad of international agencies, regulators, and commercial players. It involves many participants, including veterinarians, maritime surveyors, stock handlers, ship's crews, ship owners … their agents, exporters, and various regulators. In such a context, there are no simple solutions and there is no single body or agency with ultimate control. In addition, we note the obvious: rules and regulations themselves cannot necessarily prevent tragedies and accidents."
