Haribo has urgently recalled packets of sweets after they were allegedly found to contain cannabis when several people fell ill.

The substance was reportedly discovered after several members of the same family, both children and adults, felt unwell after eating Happy Cola F!ZZ and contacted the police.

An investigation into the sweets has been launched, according to a spokesperson for the Netherlands Food and Consumer Product Safety Authority (NVWA).

The NVWA said it was involved in the probe and confirmed ‘samples were taken and cannabis was found in them.’

‘We immediately contacted Haribo and they issued a safety warning,’ a spokesperson for the NVWA told Hart van Nederland.

‘How the cannabis ended up in the sweets is still unknown. The police are investigating this further,’  the NVWA added.

Haribo earlier said that there were products in circulation that can cause health problems, such as dizziness.

A company spokesperson said: ‘The incident is contained to the Netherlands, to a specific product and batch. HARIBO products in the UK are not affected.

‘The safety of our consumers is our highest priority and HARIBO takes this incident very seriously, which is why a recall has been issued in the Netherlands. 

‘HARIBO is working closely with the authorities to support their investigation and establish the facts around the contamination.’

The recall applies to packages with the production code L341-4002307906. 

Other production codes of Happy Cola F!ZZ, and all other Haribo products, should be safe to eat, according to the company. 

Consumers are asked by the candy manufacturer not to return the product to the store, but to send it to the company. They will then receive a refund. 

It is not yet clear what the size of the contaminated batch of sweets is.
