Horse meat keeps turning up in other forms of meat, and there is little to indicate that the practice of mixing and mislabeling meat has slowed down. A week ago, two food factory managers in the Netherlands were arrested. Workers there say that factory’s meat was routinely about one-fourth horse, and U.K. investigators think they have identified the English source of many of the horses delivered to the factory. In France, the bankrupt Spanghero meat-packing factory is expected to shut down, some believe as soon as tomorrow, its reputation and finances ruined by its tons of recalled horse meat. In the United Arab Emirates, there are calls for testing of imported meat, with worries that it contains undisclosed horse. Separately, there are scandals about pork being similarly mixed and mislabeled.
