I clearly believe that there is a virus here that is very similar to the ISA virus in Europe … [but] we have not established that it causes disease,Dr Kristi Miller – head of molecular genetics at the federal (DFO) Pacific Biological Station in Nanaimo, British Columbia, – one of four ISA experts to testify at the Cohen Commission of Inquiry into the Decline of Sockeye Salmon in the Fraser River which reconvened Thursday (Dec. 15; continues Dec. 16 & 19) in Vancouver. “In my view … I think there’s evidence there are ISAV sequences in fish samples from B.C.,” said Dr Fred Kibenge, chair of the department of pathology and microbiology at the University of Prince Edward Island (PEI), one of only two ISA reference labs in the world certified by the OIE, the World Organisation for Animal Health. “I think the result is credible. Now, whether it’s ISA or ISA-virus-like, that requires some work,” said Dr Kibenge. On Dec. 2, the Canadian Food Inspection Agency (CFIA) had stated: “[…] Pacific salmon appear to be resistant to the disease.” Queried further by SeafoodIntelligence.com, CFIA stated on Dec. 13: “We say ‘appear to be resistant’ because in an experimental study where virulent ISAV was injected into three of the five species of Pacific salmon, the salmon did not develop the disease nor is there evidence of replication.” The 2003 study to which CFIA refers tested Chum, Chinook & Coho; but not Sockeye: the species at the heart of the Cohen Inquiry’s focus. Asked specifically about the existence – or not – of ISAv virulence testing on Sockeye, DFO told us Thursday (Dec. 15) it was “following-up with [DFO] staff who are best positioned to address the questions [SeafoodIntelligence] raised. We will be in touch once those consultations are completed”.
