By means of a quick and reliable procedure, the new method can determine the level of this toxin in fresh and in canned fish. It can also be used in products from other food industries, such as red, white and sparkling wines, milk, cheese and fish meal.

INTI scientists explain that the technique "relies on the use of immunogens, haptens or antibodies marked with an enzyme whose colourful product can be measured spectrophotometrically."
Researchers Carolina Spath and Guillermo Carrizo have ensured that this principle has the properties of an ideal immunoassay.
"It is versatile, robust, simple to apply; it uses economical reactive substances, has specificity between a reactive substance and an analyte, reproducibility of results, simplicity, speed and it offers the possibility of analysing several samples simultaneously," it has been pointed out.
Histamine poisoning is chemical poisoning due to the intake of foods containing high levels of this toxin. Poisoning caused by fish consumption is the most common because the microorganisms responsible for its appearance act when fish temperature is above 15 ºC.
This is why it is essential to maintain fish refrigeration temperatures from the moment the fish is caught until it is consumed to avoid the appearance of the enzyme that produces histamine.
This type of poisoning is known as scombroid poisoning because it is linked to the consumption of fish specimens of the families of Scomberesocidae Scombridae, such as tuna, bonito and mackerel. In addition, species like mackerel, anchovies and sardines can also develop high levels of histamine.
This toxin levels permitted in fish vary according to the criteria of each region. The European Community sets 100 ppm (parts per million) of histamine while the

The importance of determining the levels of histamine in fish is that this index is considered a quality criterion.
(vasep.com.vn) VASEP has officially announced the program for Vietnam Seafood Summit 2026 (VSS 2026), featuring five in-depth sessions covering industry outlooks, trade barriers, buyer demand, the domestic market, and solutions to improve productivity and reduce costs across the seafood value chain.
(vasep.com.vn) Vietnam’s shrimp exports reached US$3.7 billion in the first nine months of 2026, up 11% year on year. Although growth has been supported by China and several markets within the CPTPP, momentum is slowing as exports to the United States and the European Union decline. Tariff pressures, international competition, and raw material challenges are creating significant hurdles for exporters in the final months of the year.
(vasep.com.vn) Markets are changing faster, buyer requirements are becoming more demanding, and trade barriers are growing increasingly complex. In this environment, seafood businesses need more than an understanding of current market conditions. They need a longer-term perspective to answer a critical question: Where will growth opportunities come from in 2027–2029, and what should businesses do now to prepare? This is one of the key reasons why VASEP is organizing Vietnam Seafood Summit 2026.
(vasep.com.vn) In the first eight months of 2026, Vietnam’s pangasius exports to the Middle East reached US$113 million, up 7% year on year from the same period in 2025. Growth has become more pronounced in recent months. In August alone, exports to the region totaled US$20 million, an increase of 24%. This indicates that demand for Vietnamese pangasius in the Middle East is gradually recovering after a slowdown in March, although the pace of recovery varies across markets.
(vasep.com.vn) China’s shrimp imports continued to grow strongly in 2026, while Vietnam’s shrimp exports to the market also recorded notable growth. However, behind these positive figures lie two distinct trends: Chinese consumption is growing more slowly than imports, and lobster accounts for a substantial share of Vietnam’s shrimp exports to China, making its product mix significantly different from those of Ecuador and India. Exporters therefore need to assess each segment carefully to understand the opportunities and risks.
(vasep.com.vn) Changing markets, shifting buyer demand, and increasingly complex trade barriers are raising a key question for Vietnam’s seafood industry: Where will the new growth opportunities lie in 2027–2029?
(seafood.vasep.com.vn) As of the end of August 2026, Vietnam’s tilapia exports to the United States reached $21 million, representing a steep 48% year-over-year decline and accounting for 23% of the country's total tilapia export turnover. Frozen fillets accounted for 78% with the remainder consisting of whole frozen tilapia and frozen cuts.
(seafood.vasep.com.vn) After a volatile first half of the year, Vietnam’s pangasius exports to Brazil registered robust growth in July and August 2026. In August alone, export turnover reached $19 million, surging 73% compared to the same period in 2025. Cumulatively for the first eight months, total export value reached $124 million, reflecting an 8% year-over-year increase.
(seafood.vasep.com.vn) Besides modifying their boats, many fishermen in Dak Lak province are making efforts to venture out to sea to harvest seafood during the rough sea season.
(seafood.vasep.com.vn) At the Responsible Seafood Summit and TCRS Shrimp Summit 2026, organized by the GSA (Global Seafood Alliance) in Bangkok, Thailand, the conversation about the future of the shrimp industry began with one of its most important foundations: seedstock quality.
