Australian doctors are reporting the first local cases of Haff disease, after a family of three developed rhabdomyolysis after eating a queen snapper. 

The trio presented with severe myalgia affecting proximal and distal limb muscles about 10 hours after eating the recently thawed and baked fish, according to doctors at Sir Charles Gairdner Hospital in Perth. 

The son, in his 20s, also described passing painless, dark brown coloured urine six hours before presentation and said he had eaten two portions of the snapper.

His parents, in their late 50s, only had symptoms of myalgia; both reportedly only ate a portion each.
