Food manufacturers are recalling several types of pre-packed sandwiches, wraps and salads sold in major supermarkets because of possible contamination with E. coli.
E. coli bacteria have not been detected in the products but are being recalled as a precaution. It is understood these are products containing salad leaves.
Retailers involved include Aldi, Asda, Co-op and Morrisons.
Some 211 people are known to currently be affected by E. coli - up from 113 last week.
At least 67 people have been admitted to hospital, the UK Health Security Agency says.
Experts had previously said a recent outbreak of E. coli was linked to food that was widely and readily available.
One of the suppliers involved, Greencore Group, has recalled 45 different products so far.
