Hong Kong’s Consumer Council has issued a stark warning after testing 30 common brands of ham and turkey slices, revealing that nine out of ten samples contain dangerously high sodium levels that could increase the risk of hypertension. The watchdog also detected preservatives and nitrates in every product, with two samples containing trace amounts of plasticisers.
The comprehensive lab analysis, conducted for the council’s Choice magazine issue 542, examined 23 ham varieties and seven turkey slice products widely available in local supermarkets. The findings paint a troubling picture for consumers who consider these processed meats a convenient, high-protein lunch option.
Sodium Levels Exceed Safety Thresholds
According to Hong Kong’s Centre for Food Safety, any food containing more than 600 milligrams of sodium per 100 grams is classified as high-sodium. The test results showed ham averaging 937 mg per 100 g, while turkey slices averaged 888 mg per 100 g. A single slice of the worst offender, 759阿信屋 (759 Ah Son House), clocked in at 1,320 mg per 100 g—meaning just one piece delivers 528 mg of sodium, or 26% of the World Health Organization’s recommended daily limit of 2,000 mg.
The second highest was 超值牌 (Super Value Brand). At the other end of the spectrum, the lowest-sodium ham sample contained 500 mg per 100 g, which still approaches the high-sodium threshold.
For turkey slices, every single sample exceeded the 600 mg mark. The highest contained 1,100 mg per 100 g, while the lowest measured 648 mg.
Preservatives and Plasticisers Raise Concerns
Beyond sodium, the council found that all 30 products contained either nitrate or nitrite preservatives—compounds used to maintain colour and prevent bacterial growth. While these additives are permitted under local food safety regulations, long-term consumption has been linked to potential health risks, including certain cancers.
More alarming was the discovery of trace plasticisers in two samples. Though the levels were within legal limits, the presence of these endocrine-disrupting chemicals in processed meat products adds another layer of concern for regular consumers.
5-Star Recommendations for Health-Conscious Shoppers
The council awarded five-star ratings to products that combined lower sodium content with minimal additives. Among ham, several brands achieved this top score, while a handful of turkey slice products also received the council’s seal of approval. Consumers are advised to check the product’s per-100 g sodium content before purchasing and to limit portion sizes.
What This Means for Your Diet
For the average Hong Kong resident who frequently adds ham or turkey to sandwiches, noodles, or breakfast plates, the council recommends treating these items as occasional condiments rather than primary protein sources. “Even a product labelled ‘low-fat’ or ‘high-protein’ can be a sodium bomb,” the report notes.
Dietitians suggest pairing processed meats with fresh vegetables, choosing whole-grain bread, and drinking plenty of water to help offset sodium intake. Those with existing hypertension or kidney conditions should be especially cautious.
Next Steps for Consumers and Regulators
The Consumer Council has called on manufacturers to voluntarily reduce sodium levels and to improve labelling transparency. In the meantime, shoppers can refer to the full Choice report online for a complete ranking of all 30 tested products, including specific sodium figures and star ratings.
For households looking to make healthier choices, the council’s advice is simple: read the nutrition label carefully, opt for products with under 600 mg sodium per 100 g, and treat processed meats as an occasional indulgence rather than a daily staple.
