Nurseries cease serving tinned tuna over mercury content

The director of a group of nurseries has stated that prohibiting tinned tuna and substituting it with pilchards and mackerel was an “easy decision,” following new research indicating the potential for toxic mercury levels in the product. Cherie Wilson, responsible for overseeing 11 Acorns Nurseries locations throughout south Wales and south west England, indicated that the choice stemmed from discussions held with both parents and culinary staff. A study conducted by the campaign organizations Bloom and Foodwatch involved testing 148 cans of tuna sourced from five European nations, with every sample showing positive results for mercury contamination. Europêche, the organization representing fishing fleets within the EU, declared that it “strongly refutes” these assertions, adding that the quantities necessary to present a health hazard are “significantly higher” than typical consumption levels. Ms Wilson commented, “We heard that tuna may pose a risk over time, especially with young children.” She expressed surprise upon learning of the findings, noting that tuna had “always been an option” on their menu previously. Since then, alternative options have been implemented at Acorns Nurseries, which operates sites in locations such as Bristol, Cardiff, and Newport. She stated, “We are offering other oily fish such as pilchards and mackerel, which supports the growth and development in children.” The conducted tests confirmed that all 148 tuna cans examined contained mercury contamination. These samples were acquired in France, Germany, England, Spain, and Italy. At present, both EU and UK regulations establish the maximum mercury level in tuna at 1mg/kg. This mercury threshold is three times greater for tuna compared to other types of fish. Aisling Pigott-Jones, a British Dietetic Association member practicing in Wales, believes the campaigners’ concerns are valid. She suggested that tinned tuna consumption should be “limited for children” but does not support a ban in schools. She explained, “Eating tuna too regularly can mean higher than recommended mercury intake.” She added, “About twice a week is recommended as safe for children.” She emphasized the advantages of consuming this saltwater fish, noting its comparatively low cost. She remarked, “Tinned tuna is a good source of protein for young people, especially in the cost of living crisis”. She mentioned the availability of other choices, including tinned salmon, sardines, and mackerel. This toxic element is discharged through coal mining and combustion, eventually entering the ocean. It accumulates in tuna as they consume prey that has been contaminated. Individuals are subsequently exposed to this element upon consuming the fish, which is among the most widely eaten globally. John West, the largest tinned tuna brand in the UK and owned by the Thai Union Group, stated: “The tuna products we supply to UK and European retailers are safe for consumers.” The company added, “In the past three years, we have carried out hundreds of checks. The results have never revealed mercury levels higher than the British and European standards in place, averaging between 0.2 and 0.3 mg/kg – 70 to 80% below the permitted limit.” Mark Willis, from the Food Standards Agency, advised that pregnant individuals should limit their tuna consumption to a maximum of four cans per week. However, he also noted that mercury is present in all fish, making it impossible to “eliminate entirely.” The Food Standards Agency confirmed it continuously monitors contaminants like mercury in food. As part of the Welsh government’s initiative to address child poverty, primary school children throughout Wales receive free school meals. The Welsh government stated: “All local authorities and governing bodies of maintained schools must comply with the Healthy Eating in Schools Regulations 2013.” It further added: “The Food Standards Agency in Wales has government responsibility for food safety and any change to what can be provided in school meals on a food safety basis would be based on their advice.”
