The E. coli cases linked to carrots comes after another high-profile outbreak in the US, related to slivered onions on some McDonald's Quarter Pounder burgers.

McDonald's suspended sales of the Quarter Pounder burger in October in about a fifth of its US restaurants in response to the outbreak.

"I remember taking out what looked like a burger patty and placing it in a hot pan. As it cooked it started looking like a well-seared steak."

The fast-casual burger spot Shake Shack closed nine underperforming restaurants in September, including five in the Los Angeles area.

It was for an advert with a well-known burger chain - despite the fact she is vegan.
