SCOMBROID/ˈskɒmbrɔɪd/

Of or relating to a class of fish that includes the mackerel.

This is a moderately common technical term in zoology, deriving ultimately from the Greek scombros for the mackerel or tunny, which also led via Latin to scomber as an uncommon English word for the mackerel, which is now only used as the formal name for the genus. The scombroid fish are a group of about 100 species that include the mackerel, tuna, marlins and swordfish. You are most likely to encounter the word in the phrase scombroid poisoning, which is caused by eating fish that contains histamines produced by bacterial activity as a result of poor storage. As you can get this through eating other spoiled foods such as cheese, perhaps the alternative name of histamine poisoning is more suitable.
