Hong Kong’s consumer watchdog tested 30 popular packaged ham and turkey products, uncovering startling levels of sodium, chemical preservatives, and traces of ractopamine—with only two brands earning top marks.
A quick sandwich may seem like the lighter choice for breakfast or afternoon tea, but new testing by Hong Kong’s Consumer Council reveals that packaged ham and turkey slices often carry a heavy health burden. The watchdog examined 30 varieties commonly found on local supermarket shelves and found that more than 90% qualified as “high sodium” foods—a classification that spells potential trouble for blood pressure with regular consumption.
Beyond the salt problem, every single sample contained nitrates or nitrites used as preservatives and colour retainers. Even more concerning, two products showed traces of plasticisers, while two others tested positive for ractopamine, a feed additive more commonly known as “lean meat powder.”
Two Brands Rise Above the Rest
After rigorous evaluation, only two products earned the Council’s coveted five-star rating:
- M&S Food British Lean Ham Low Fat
- Ferrarini Smoked Turkey Breast
These selections stood out for their relatively better nutritional profiles and lower levels of undesirable additives.
The Salt Reality Check
Sodium emerged as the biggest concern across the board. Among the samples, the highest-sodium ham product was 759Store Ham Sliced, while Maid Brand Sandwich Ham Slices and Yu Pin King Sandwich Ham Slices 1lb also posted elevated figures. On the turkey side, Buddig Oven Roasted Turkey carried the most salt, while a notable exception came from an Organic Smoked Turkey Breast containing 648 milligrams per 100 grams—on the lower end of the spectrum.
According to World Health Organization guidelines, adults should consume less than 2,000 milligrams of sodium daily. A single serving of some tested products could account for a quarter of that allowance.
Chemical Additives: What Was Found
All 30 samples tested positive for either nitrates or nitrites, though levels remained within Hong Kong’s legal limits. The Council noted that consuming these preservatives in permitted quantities at normal serving sizes poses no immediate health risk.
Two samples contained DEHP, a type of plasticiser, at concentrations of 0.10 and 0.12 milligrams per kilogram—well below the Centre for Food Safety’s action level of 1.5 milligrams per kilogram.
Ractopamine Residues Detected
Two tested products showed ractopamine residues at 1.2 and 2.0 micrograms per kilogram. While these amounts fall beneath both Hong Kong’s action levels and the Codex Alimentarius Commission’s maximum residue limit of 10 micrograms per kilogram for pig muscle, the Council flagged potential health implications. Excessive intake of ractopamine can stimulate beta-adrenergic receptors, potentially causing heart palpitations, tremors, and dizziness. Individuals with heart conditions or blood pressure disorders face higher risks of severe reactions.
What This Means for Your Shopping Cart
For health-conscious consumers, the Council’s findings offer practical guidance. Seven products were free of nitrites, and one sample contained no nitrates at all. Choosing these options alongside the two five-star rated brands can meaningfully reduce additive exposure.
Reading nutrition labels before purchase remains the most reliable strategy. Look beyond front-of-package claims like “low fat” and check per-100-gram sodium figures. The WHO’s “high sodium” threshold starts at 600 milligrams per 100 grams—a benchmark worth memorising for your next grocery run.
The full test results, including the complete product list and detailed findings, are available on the Consumer Council’s website under Issue 542 of their monthly publication.
