Many of the difficulties that have been experienced by Health Authorities in this country in the examination of imported butcher's “offal”—using the term “offal” in its trade sense—would seem to have been due to injudicious methods of packing on the other side. The organs that constitute “offal”—livers, plucks, kidneys, sweetbreads, and so forth—have hitherto been closely packed into a bag, box, or crate, and the whole mass then frozen hard. Hence on arrival at the port of inspection the separate examination of these organs for possible disease conditions was rendered a matter of extreme difficulty. The exporters have now, it appears, almost all arranged for the separate freezing of the larger organs before packing, and in the case of smaller organs, such as kidneys and sweetbreads, some packers now make use of shallow boxes.
