'Blurred vision'

Botulism is rare in the UK. It is caused by toxins produced by the bacterium Clostridium botulinum, which attacks the nervous system.

The two children have been treated with antitoxins.

The Health Protection Agency (HPA) has notified health professionals throughout the UK to be on the lookout for people with possible symptoms.

These can include blurred vision, difficulty swallowing, headaches and muscle weakness.

Dr Kathie Grant, a botulinum toxin expert at the HPA, said: "Cases of botulism are thankfully very rare in the UK, although it can be a very serious infection in those that are affected.

"We urge the public to take heed of this message and ensure that they immediately dispose of this product and to be aware of the signs and symptoms of botulism."

The infection is not passed from person to person. Symptoms can occur between 12 and 36 hours after eating contaminated food.
