Hong Kong’s Consumer Council has uncovered that sodium levels in popular canned dace fish products can vary by nearly 100 percent, with one award-winning brand costing just HK$23.9 earning top marks for safety and quality in a comprehensive test of 46 canned fish varieties.
The watchdog’s latest report, published in Choice magazine issue 525, examined seven brands of canned dace with fermented black beans—a staple in Hong Kong kitchens. Researchers from accredited laboratories analyzed each product’s fish content after removing sauce and seasonings, testing for metal contaminants, prohibited dyes, polychlorinated biphenyls (PCBs), and nutritional composition.
Staggering Sodium Disparity
The findings highlighted a dramatic range in sodium content across the seven dace samples, priced between HK$15.9 and HK$23.9 per can. Four brands—Tin Lung, Eagle’s Gold, Pearl River Bridge, and Great Wall—contained over 1,000 milligrams of sodium per 100 grams of fish, placing them in the “high sodium” category under local food regulations.
Consumers consuming a full can of the highest-sodium brand, Eagle’s Gold, would ingest approximately 880 milligrams of sodium—exceeding 40 percent of the World Health Organization’s recommended daily limit for adults and 50 percent of the daily intake suggested for a seven-year-old child by Chinese dietary guidelines.
Top Performer: Eagle’s Gold Earns Five Stars
Despite its higher sodium content, Eagle’s Gold emerged as the sole product to receive a perfect five-star overall rating. Priced at HK$23.9, it performed admirably in metal and pollutant tests, with all contaminants falling below legal limits.
All dace samples contained trace metals, but none exceeded regulatory thresholds. Only Pearl River Bridge showed minor dioxin-like PCBs, which would require excessive consumption to pose health risks.
Calcium Bonus from Soft Bones
Canned dace offers an unexpected nutritional advantage. The high-pressure canning process softens fish bones, allowing consumers to eat them whole and boost calcium intake. Kam Chuk brand led the category with 910 milligrams of calcium per 100 grams—meaning a seven-year-old eating just 109 grams (about 0.6 cans) would nearly meet their daily calcium requirement.
However, the trade-off is clear: dace had the lowest levels of beneficial omega-3 fatty acids (DHA and EPA) among all canned fish tested.
Expert Advice for Health-Conscious Shoppers
Nutritionists recommend moderation when consuming canned dace. The Consumer Council advises checking labels carefully, as sodium content listed on packaging includes the entire product—fish, oil, and black bean sauce. For Eagle’s Gold, a single serving of 55 grams (one-quarter can) contains only 283 milligrams of sodium from the fish alone, but consuming the whole can more than triples that amount.
Broader Implications: Bottled Water Also Under Scrutiny
In the same report, the council tested 30 bottled water brands, revealing that 13 contained plasticizers (DBP) and two—including Nongfu Spring—had bromate levels reaching the EU’s maximum limit of 3 micrograms per liter. Nongfu Spring has since issued a legal letter demanding clarification and an apology, disputing three points in the test methodology.
The Consumer Council’s findings serve as a timely reminder for Hong Kong’s food lovers: convenience often comes with hidden costs. When reaching for that familiar can of dace, reading the fine print may be just as important as savoring the flavor. For those watching their sodium intake, portion control and brand selection can make a significant difference.
