[142] The flesh of mackerel spoils quickly, especially in the tropics, and can cause scombroid food poisoning. Accordingly, it should be eaten on the day of capture, unless properly refrigerated or cured. [143]
The Chilean jack mackerel looks very much like the greenback horse mackerel (Trachurus declivis) found around Australia and New Zealand. The two species can be distinguished by the number of gill rakers ( T. declivis 50–57, T. murphyi 51–65) and the number of scales and scutes in the lateral line ( T. declivis 81–82, T. murphyi 89–113).
