Thank you for the question.
Yes, I believe I am familiar with the case that's the basis for your question. This particular grower or exporter was shipping cherries to Taiwan, and our inspector, upon a statistically valid sampling and with growing technique, found early-instar larvae. Of course, the problem with these early-instar larvae is that it's difficult even for entomologists to identify exactly what they are—whether it's going to be the cherry fruit fly, the apple maggot, or another quarantine pest.
I'll answer your last question first in. No, I'm not aware of a quick identification for it. Even for entomologists to identify it sometimes would require weeks, because they have to grow these things out to the point where they are in a form that's identifiable, which of course is not a practical solution for somebody wanting to get a perishable product across the Pacific Ocean.
But going back to this decision, when our inspectors find these larvae, the policy is to refuse to issue the phytosanitary certificate—thus, as you put it, stopping the export. Without that certificate, it wouldn't make it into Taiwan.
The reason for this is that even if he were able to identify it for sure, upon arrival in Taiwan, they apply an inspection sampling program that, from what I'm told, is far larger than ours. If they were to have the same find in Taiwan, they have the same problem of identification. Then they would give the exporter a choice of refused entry, finding another country, fumigating it, or waiting until we can identify it—which of course brings us back to the problem of having a perishable product here.
The decision to not issue the phytosanitary certificate—to make all of those marketing decisions here in Canada—is I believe the right one. Further, if this becomes an habitual situation in Taiwan or in any country, what quite often follows is that they step up their inspection program, they step up their sampling program, and we get more of this identified.
Thus the Canadian policy is strict, yes, we are thorough back here, but we believe this is the best way to protect the exporters and the reputation of the Canadian export system.
