Salmon giant Mowi's Northern Harvest site in Newfoundland and Labrador reported in late March potential infectious salmon anemia (ISA) in three Atlantic salmon parr during a routine sampling at its hatchery.

The detection has not yet been confirmed by authorities, but Mowi is required to disclose the detection under the province's stricter regulations. Those regulations were enforced following a mass die-off at Mowi's Northern Harvest operations last year.
