Rapid Methods for Detecting Histamine in Fishery Products
Imagine enjoying a delicious tuna steak only to find yourself minutes later facing a racing heart, a burning sensation in your mouth, and developing an alarming red rash. This isn't standard food poisoning; it's scombroid fish poisoning, caused by an invisible threat: histamine.
Histamine formation begins when fish aren't properly chilled, allowing bacteria to produce histidine decarboxylase enzyme that converts histidine into histamine.
Unlike many foodborne toxins, histamine remains potent even after thorough cooking, frying, or canning processes.

A 2025 study developed a novel non-enzymatic histamine sensor using boron-doped diamond (BDD) electrodes 1 . This approach eliminates the instability of enzymatic components, offering longer shelf life and greater reliability.
The researchers modified BDD electrodes with oxygen terminations and optimized pH to 8.4, creating electrostatic conditions that attract histamine while repelling histidine—solving the selectivity problem.
Boron-doped diamond electrodes were fabricated on silicon wafers and treated to create oxygen-terminated surfaces 1 .
Canned tuna samples with certified histamine concentrations were mixed with phosphate-buffered saline solution, homogenized, and filtered 1 .
The BDD electrode was immersed in sample solution, and electrical potentials were applied to measure current from histamine oxidation 1 .
The sensor was tested with known histamine concentrations to create calibration curves and validated with "unknown" samples 1 .
Provides wide potential window for detecting high-oxidation-potential compounds like histamine 1 .
Signal generation through color changes upon aggregation; easily functionalized 2 .
