Shoppers have been warned not to eat a chocolate bar following reports of illnesses in those who have.

The Food Standards Agency (FSA) said it was “strongly advising” people against eating a chocolate bar called Cali-Gold.

The bar has been available for sale in the Nottinghamshire area and relevant authorities are trying to find out if the bar has been distributed wider.

Police have reported illnesses in the area in people who have consumed the Cali-Gold chocolate bar.

One person has been arrested in connection with the incident.

Tina Potter, head of incidents at the FSA, said: “We are working with local authorities, the UK Health Security Agency and Nottinghamshire Police to investigate an incident following reports of illness after eating Cali-Gold chocolate. 

“If you have purchased ‘Cali-Gold’ chocolate from Mansfield Market in Nottinghamshire you should not consume the product and dispose of it at home.

"If you have already eaten it and developed symptoms, then you should urgently seek medical attention.”
