Is mahi-mahi vegetarian-compatible?

Watch for

• A pale fillet is not a safe fillet.Most people assume the scombroid risk belongs to dark fleshed fish, but mahi-mahi is white fleshed and is still one of the two species behind the majority of histamine poisoning reports. Judge it on the chill chain, not the colour.
• The supply chain is long.Mahi-mahi is a warm water sport and longline fish that usually reaches a northern counter by air as a thick fresh steak, and a lot of what is sold as fresh has been frozen and thawed. Frozen at sea is the version with a documented clock; a thawed steak of unknown age is the one to be careful with.
• A peppery, metallic or faintly bitter taste is the classic warning sign, and it is worth stopping at the first bite that tastes wrong.It is not reliable though: plenty of high histamine fish tastes and smells completely normal.
• Regulators treat histamine as a decomposition marker rather than a spoilage smell.The FDA now flags scombrotoxin forming fish at 35 parts per million as evidence of decomposition and 200 parts per million as a hazard, and none of that is visible on the plate.
• Tyramine also grades borderline and rises as the flesh ages, which matters on an MAOI or a migraine plan.On mercury, mahi-mahi sits in the middle tier of the FDA and EPA fish advice at roughly one serving a week rather than the lowest tier.
