Chilean farmed salmon ISA virus outbreak (2007-2010)
2007–2010: a documented market event that overlapped the wholesale price windows of 3 tracked ingredients — co-occurrence in time, never an asserted cause.
What happened
Infectious salmon anaemia virus (ISAV) was first isolated on an Atlantic salmon farm in Chile's Los Lagos region (Region X) in mid-2007 and spread along roughly 1,300 km of southern Chilean coastline over 2007-2009. Chile's Atlantic salmon harvest volume in 2009 was reported about 61% lower than in 2008, and industry and academic assessments described an overall Atlantic-salmon production decline on the order of 50% or more, with a multi-year recovery beginning around 2011. Chile is one of the world's largest farmed salmon producers.

Affected ingredients
- Salmon fillet
- Salmon
- Whole salmon
Why these ingredients were exposed
Each affected ingredient's public supply structure — where it comes from and how much it leans on imports. Context that makes the co-occurrence with a documented event legible, never its cause.
- Salmon filletWild vs imported US wild landings were $394M (2024), beside $2.46B of imports — two different measures, not a supply share. Most imports of this species are farmed abroad.
- Salmon (skin-on fillet)Wild vs imported US wild landings were $394M (2024), beside $2.46B of imports — two different measures, not a supply share. Most imports of this species are farmed abroad.
- Whole salmonWild vs imported US wild landings were $394M (2024), beside $1.08B of imports — two different measures, not a supply share. Most imports of this species are farmed abroad.
Wild landings and imports are two different measures, not a supply share. It explains why an ingredient sits in the path of a documented event — not that the event caused any price move. Co-occurrence in time, never a cause.
The detected moves that overlapped
Each figure is a wholesale reference against its own ±26-week normal — a market move, never a delivered price.
No sustained wholesale move in our detected set falls inside this event's window. The event is documented; our public price series simply didn't flag a notable departure from normal for these ingredients then — an honest absence, not a hidden one.
