The company said the packaging error
applied to a limited number of
six-packs of ready salted crisps
and, according to the Food Standards Agency, made them unsuitable for people with a soya or lactose allergy .
Walkers is to spend £7.5 million on communicating
its decision to
use only British potatoes in its crisps range.
Revamped packs will feature images of potatoes being transformed into crisps, and a series of TV ads featuring Walkers' frontman Gary Lineker will break on Aug
Outdoor, press and online ads will reinforce the changes, along with a roadshow at country fairs where consumers can select a potato and watch it being turned into crisps.
Cajun Spice flavour will also be added to the range, and Worcester sauce will be reintroduced. Cheddar cheese, lamb & mint and chilli spice have been discontinued, a spokeswoman said.
