McDonald’s have altered its burger’s ingredients after chef Jamie Oliver forced them to remove a processed food type that he labelled “pink slime”.

Chef Jamie Oliver, who is also a food activist, was shocked when he learned that ammonium hydroxide was being used by McDonald’s to convert fatty beef offcuts into a beef filler for its burgers in the USA.

The filler product made headlines after he denounced it on his show, Jamie Oliver’s Food Revolution.

“Basically, we’re taking a product that would be sold at the cheapest form for dogs and after this process we can give it to humans,” said TV chef Jamie Oliver.

Jamie Oliver showed American audiences the raw “pink slime” produced in the ammonium hydroxide process used by producers named Beef Products Inc (BPI).

“Pink slime” has never been used in McDonald’s beef patties in the UK and Ireland which source their meat from farmers within the two countries.

Now after months of campaigning on his hit US television show McDonald’s have admitted defeat and the fast food giant has abandoned the beef filler from its burger patties.

US Department of Agriculture microbiologist Geral Zirnstein agreed with Jamie Oliver that ammonium hydroxide agent should be banned.

Geral Zirnstein said: “I do not consider the stuff to be ground beef and I consider allowing it in ground beef to be a form of fraudulent labelling.”

Jamie Oliver is pleased at the decision by McDonald’s stop using the ammonium hydroxide processes meat.

He said: “Why would any sensible human being want to put ammonia-filled meat into their children’s mouths?

“The great American public needs to urgently understand what their food industry is doing.”

McDonald’s denied its hand had been forced by Jamie Oliver’s campaign.

Todd Bacon, Senior Director of U.S. Quality Systems and Supply Chain with the fast food chain, said: “At McDonald’s food safety has been and will continue to be a top priority.

“The decision to remove BPI products from the McDonald’s system was not related to any particular event but rather to support our effort to align our global beef raw material standards.

“McDonald’s complies with all government requirements and food safety regulations.

“Furthermore, we have our own food safety measures and standards in place throughout the entire supply chain to ensure that we serve safe, high quality food to every customer, every time they visit our restaurants.”

Two other chains, Burger King and Taco Bell, have earlier bowed to pressure and removed ammonium hydroxide processed ingredients from their products.
