Health chiefs beg Brits not to eat £1 ‘Cali-Gold’ chocolate bars after several people – including five children – fall ill from buying them at a Christmas market

Health chiefs today urged Brits not to eat a chocolate bar after a swathe of people who bought fell ill.

Cali Gold 70 per cent dark chocolate bars, wrapped in gold foil and inside an orange box, were sold at a Christmas market in Mansfield, Nottinghamshire on Saturday.

Police yesterday confirmed a man had been arrested after at least five children and several adults began feeling unwell after eating the snack and were taken to hospital.

Reports circulated online that the bars — which were being sold as five for £1 — were laced with opioids but officers said there is ‘no evidence to support these rumours’.

The Food Standards Agency (FSA) issued a ‘do not eat’ warning, advising anyone who has bought it to throw it in the bin and ‘urgently’ seek medical attention if they have already eaten the chocolate bar and feel unwell.
