But I also think in this case that the US beef exporters had already agreed to the higher Japanese inspection standards, and the company involved in the packing admitted they made a mistake in this case (including spinal bones with the meat, if I remember right).
So I think the case is more one of poor inspections on the US end. O focurse, you could also get into whether the risk warrants the inpection, but that is still a Japanese government call, as it their health standards we are talking about (not the US standards).
