The Hong Kong Consumer Council has issued a stark warning following its latest investigation into cold cuts, revealing that more than 90 percent of 30 tested ham and turkey slice samples are classified as high in sodium. This finding, published in the council’s Choice magazine issue 542, challenges the perception of these products as healthy breakfast or lunch options and underscores the potential long-term risk of hypertension from regular consumption. The study also found that all samples contained preservatives or color fixatives, while a select few carried trace amounts of plasticizers and the controversial feed additive ractopamine.
High Sodium: A Widespread Concern
Of the 30 ham and turkey slice products analyzed, 28 were deemed high in sodium, meaning they contain more than 600 milligrams per 100 grams. The highest sodium content was found in 759 Store’s ham slice, which packs 1,320 mg of sodium per 100 grams. Consuming just one 40-gram slice would account for 26 percent of the daily sodium intake limit recommended by the World Health Organization. The lowest sodium ham option was Tesco’s Prime Cuts Honey Roast Ham, with 500 mg per 100 grams. A single 56-gram package of Buddig’s Oven Roasted Turkey—the saltiest turkey slice tested—provides 31 percent of the daily limit, delivering 616 mg of sodium. These levels pose a clear risk for hypertension, particularly when combined with other dietary sodium sources.
Preservatives and Additives Detected in All Samples
Every product in the test contained either nitrates or nitrites, which serve as preservatives and color enhancers. Nitrate levels ranged from 1.78 to 18.3 parts per million, while nitrite levels fell between 0.423 and 33.2 ppm. Although none exceeded Hong Kong’s legal limits, the council noted that long-term intake of these additives may still have health implications. Encouragingly, Ferrarini’s Smoked Turkey Breast was entirely nitrate-free, and seven products—including M&S FOOD’s British Lean Ham Low Fat and True Story’s Organic Smoked Turkey Breast—contained no detectable nitrites. The council emphasized that normal consumption of these products at permissible additive levels poses no immediate health risk.
Plasticizers and Ractopamine in Select Brands
Two samples tested positive for di(2-ethylhexyl) phthalate (DEHP), a plasticizer that can disrupt endocrine function at high exposure levels. The detected quantities—0.10 and 0.12 milligrams per kilogram—were well below the Centre for Food Safety’s action threshold of 1.5 mg per kilogram. To match the highest finding, a consumer would need to eat over 25 kilograms of the product daily for health effects to appear.
Additionally, two ham samples from 金妹牌 (Maid Brand) and 御品皇 (Yu Pin King) contained ractopamine residues at 1.2 and 2.0 micrograms per kilogram—both within Codex Alimentarius limits for pork. Ractopamine, a feed additive used to promote lean muscle growth, can trigger side effects like heart palpitations and tremors when consumed in excess, especially in individuals with preexisting heart conditions.
5-Star Recommendations for Healthier Choices
Among the 30 products, only two earned a perfect 5-star rating from the Consumer Council:
- M&S FOOD British Lean Ham Low Fat – praised for its lower sodium and additive profile
- Ferrarini Smoked Turkey Breast – recognized for being nitrate-free and balanced in nutrition
Consumer Takeaways and Next Steps
The council advises reducing overall intake of processed ham and turkey slices to lower sodium exposure. For those who still enjoy these products, choosing options with no added nitrates or nitrites—such as the seven nitrite-free picks—can help. Reading nutrition labels for sodium content per serving and opting for brands with the highest ratings are practical strategies. This report serves as a call for manufacturers to improve formulations and for regulators to consider tighter limits, ensuring that everyday sandwich choices do not silently compromise public health.
