NAIROBI, Kenya — The Kenya Bureau of Standards (KEBS) has dismissed claims that sulphur-based sweeteners are being secretly added to sugar-free soft drinks without proper consumer warnings.
The regulator issued the clarification after the Consumer Federation of Kenya (COFEK) alleged that some sugar-free drinks in the Kenyan market contain sulphur-based sweeteners such as Acesulfame-K, which it claimed are unfit for human consumption.
“Why are ‘sugar-free’ drinks sneaking these additives into tiny, unreadable ingredient lists with zero allergy warnings, yet wine makers clearly warn consumers? Who is protecting consumers here?” COFEK said in a post on social media.
KEBS Cites International Standards
In response, KEBS said the allegations were misleading and ignored existing international safety thresholds.
According to the standards body, manufacturers are only required to declare sulphur-containing ingredients when concentrations exceed 10 milligrams per kilogram (10mg/kg).
The threshold is set by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) through their joint expert committee.
“The Kenya Standards have a threshold of 10mg/kg as set by the WHO/FAO expert committee on allergies and chemical reactions beyond which any product containing sulphur-containing ingredients must declare,” KEBS said.
“It is not true that there are ingredients being sneaked into products,” the board added.
KEBS explained that the threshold is designed to protect consumers who may be sensitive to sulphur compounds, including individuals prone to allergic reactions.
Additives Subject to Approval
The regulator said all food additives used in soft drinks undergo scrutiny before approval for use in the country.
KEBS further stated that manufacturers are legally required to list all ingredients on product labels, in line with Kenya’s food labelling and safety regulations.
The agency maintained that compliance is monitored through routine inspections, laboratory testing, and enforcement actions where violations are detected.
Growing Scrutiny of the Soft Drinks Industry
The clarification comes amid increased public debate and policy interest in the regulation of soft drinks, particularly sugar-free and low-sugar beverages.
The government has signalled plans to tighten oversight of the industry as part of broader efforts to address rising cases of diabetes, obesity, and other non-communicable diseases.
In May last year, Nandi Hills MP Bernard Kitur proposed the introduction of a Health Promotion Levy on sugary beverages during public hearings on the 2025 Finance Bill.
Kitur argued that the levy would incentivise manufacturers to reformulate products with lower sugar content while generating revenue for public health and school nutrition programmes.
“The increasing consumption of sugar-sweetened beverages in Kenya has contributed significantly to rising cases of obesity, diabetes, and other non-communicable diseases,” Kitur said.
“To mitigate this public health crisis, we propose the introduction of the Health Promotion Levy in the soft drinks industry,” he added.
KEBS urged consumers to rely on verified regulatory guidance and official standards, warning that misinformation could undermine public confidence in food safety oversight.
