After publishing urgent allergy advice on 20th September and following extensive food chain analysis, on-going investigations by the FSA have traced the contaminated mustard ingredients to three suppliers in India.
These producers have supplied three spice companies in the UK, which have subsequently distributed the ingredients to a range of manufacturing, hospitality and retail businesses.
A FSA spokesperson said: “We have put out advice to consumers with a peanut allergy, to inform them not to eat food that contains or may contain mustard, mustard seeds, mustard powder or mustard flour because of potential contamination with peanuts.
“This is due to the potential scale of products affected, and the severity of some allergic reactions to peanuts. Food eaten out, including in catering settings like schools could also be affected. This is why we are asking people with a peanut allergy, or their parents or carers, to check with those supplying the food whether it contains mustard.”
