The world's biggest sandwich chain has been implicated in a food
poisoning outbreak that has claimed 120 victims and left one person
dead.

It appears that meat contaminated with salmonella was used by Subway
in its sub rolls, which were then served up in outlets across the UK
and Ireland. But health officials have warned that the toll of those
affected may be much higher because many did not go to their GP or
public health authority after becoming ill.

The outbreak has mainly affected young adults, although one child aged
just 12 months is known to have fallen ill.
