The detection is carried out using a camera or a smartphone, which makes it easy for consumers to use.
The ECSens research group from the University of Granada (UGR), made up of researchers from the Department of Analytical Chemistry and the Department of Electronics and Computer Technology, has developed an innovative sensor that allows the determination of the freshness of packaged foods such as fish through a color change. This sensor, made with natural compounds such as turmeric and red cabbage, “is biocompatible and non-toxic, allowing its direct contact with food”
The sensor developed, indicate the same sources, detects the presence of ammonia - a compound that is released during the decomposition of fish - and, depending on the concentration of ammonia in the packaging, the sensor changes color, thus indicating the level of freshness of the product.

Health authorities in France have issued an alert regarding the voluntary recall of fresh albacore tuna loins under the Bigfish brand after detecting histamine, a toxin that causes severe food poisoning and allergic reactions.
The fish, sold vacuum-packed with skin in 2 and 6-kilo formats, was distributed between August 4 and August 7, 2026, through Super U in Plouarzel. The action targets batch 26072026, featuring traceability code MDV/LHP/ALAM6/23G26/YFT and an expiration date of August 9, 2026.
The official body RappelConso, which released the notification on August 17, 2026, urges consumers not to eat the product and to return it to the point of purchase for a full refund. Consuming this toxin can rapidly trigger symptoms such as flushing, facial swelling, headaches, nausea, vomiting, or gastrointestinal distress.
The latest penalty brings fines imposed on foreign vessels for illegal fishing in Argentine waters during 2026 to more than ARS 4.533 billion.
Argentine authorities sanctioned the Hai Xing 2, a Chinese-origin vessel sailing under the Tanzanian flag, after detecting fishing activity inside the country’s Exclusive Economic Zone (EEZ) near Golfo San Jorge.
The vessel received a fine of nearly ARS 1.9 billion, becoming the fourth foreign fishing vessel sanctioned by Argentina in 2026 for illegal operations in waters under national jurisdiction.
FFA-coordinated surveillance operation strengthens regional efforts to detect and deter illegal fishing across Pacific waters.
The Pacific Islands Forum Fisheries Agency (FFA) flagged 16 vessels for further investigation during a regional surveillance operation targeting illegal, unreported and unregulated (IUU) fishing. The coordinated crackdown reinforces cooperation among Pacific nations to identify suspicious fishing activity, improve compliance and protect the region’s valuable tuna and marine resources.
The 3D-COAST system is designed to automate oyster handling, cut labor needs and produce up to 125,000 oysters per raft annually.
An oyster farm in Maine, US, is testing 3D-COAST, a floating vertical conveyor powered by two solar panels. The technology moves oyster baskets between water and air, automating tumbling and helping control biofouling.
Nissui targets 10,000 tonnes by 2030 as domestic production gains momentum.
Japan’s salmon farming sector is expanding, especially in Tohoku, driven by strong Asian demand and rising costs. Nissui plans to increase annual production from 4,200 tonnes to 10,000 tonnes by 2030.
The measure runs until October 15, 2026, covering fishing, trade, storage and export along all Omani coasts.
Oman has imposed its seasonal kingfish ban to support stock recovery and sustainable fisheries. In 2025, production reached 19,743 tonnes, worth RO 44.4 million. Violations may result in fines of up to RO 300 and imprisonment.
Time-temperature, colour-changing labels help airlines, cruise lines, and rail operators protect perishable food quality from preparation to onboard service
Vitsab®, a global leader with over 20 years of temperature monitoring expertise, is proud to highlight Freshtag® Onboard Catering, a colour-changing, full-history smart indicator designed to monitor passenger meals and other perishable products in refrigerated or passive storage environments for time/temperature abuse from the preparation kitchen until service onboard. By giving operators an easy-to-read visual indicator powered by Freshtag’s stoplight technology, which provides a simple colour-based cue, Freshtag Onboard Catering helps teams quickly validate whether onboard food has remained within safe handling conditions throughout transport, storage, and service.
Chile’s Constitutional Court has struck down a measure that would have made it easier for salmon farmers to move existing aquaculture concessions, dealing a setback to efforts to loosen regulatory constraints on the sector.
The court said in a communiqué dated August 13 that it had declared unconstitutional provisions creating so-called “micro-relocations” and exempting them from Chile’s Environmental Impact Assessment System.
The measure would have covered movements of up to 350 metres from the original concession area.
