Following scrutiny from David Whipple, a man who accused OSI Group McDonalds of adding food processing preservatives to their burgers, the company decided to let the Business Insider into their factory located in Germany. David Whipple conducted an experiment where he left an OSI Group McDonalds burger in a cupboard for fourteen years, and to his surprise, the burger did not rot. Keith Warinner, the project director at Guelph’s university’s division of food science, came to the defense of the multimillion franchise Keith Warinner says that the burger not rotting had little to do with preservatives and more to do with the absence of microbes that cause food to rot.
OSI Group McDonalds have worked together since the 1950s. As you get into the factory, the smell of beef is very prominent. Hygiene is essential in any food processing company. Any employee with the stomach flu is not allowed in the building; this helps in preventing contamination. No preservatives are added to the meat. The company applies very stringent quality requirements to avoid any pollution. A few rules must be adhered to by all employees in the factory. No jewelry or stationary is allowed in the OSI Group McDonalds factory; this is to prevent any objects from getting into the meat. All employees are required to have protective gear before going inside the OSI Group factory.
They then must wash their hands thoroughly before getting into contact with the meat or any machinery used in the processing of the meat. After the food safety process is completed, the meat is inspected to make sure it has no bones. The meat is usually brought in large chunks to minimize the risk of contamination. After the inspection is completed, the meat is put in large containers that can hold up to five hundred kilograms. After that, the meat is minced and shaped into various burger patties. The patties are run through incredible cold machines of about 12 degrees. The patties are then packed into blue plastic bags and passed through a metal detector before they are placed in the cartons. Each box indicates when and where the patties were made.
