According to the United Kingdom Health Security Agency (UKHSA), French public health authorities have reported an outbreak of foodborne botulism linked to one restaurant in Bordeaux. A small number of British nationals is reported to have been affected.
The outbreak is linked to marinaded sardines served by the Tchin Tchin Wine Bar in Bordeaux. People who ate at the Tchin Tchin Wine Bar, Bordeaux between 4 and 10 September 2023 are advised to contact the nearest Emergency Department.
Symptoms of botulism can develop within a few hours to several days after exposure. In food borne botulism gastrointestinal symptoms such as nausea, vomiting, diarrhoea, may precede neurological symptoms but are not always present. It is noted that initial symptoms of diarrhoea could be followed by constipation. Neurological symptoms may include generalised / facial weakness, visual impairment, fatigue, paralysis, breathing and/or swallowing difficulties
Treatment may include administration of botulinum anti-toxin, and severe cases often require intensive care treatment. If treatment is successful, complete recovery can take weeks to months. The fatality rate following food-borne botulism is 5-10%.
