It is not clear whether the contaminated products are genuine Haribo bags or fake.
His visit follows a series of business deals announced by the Trump Organization, which is run by the president's sons, Eric and Donald Jr.These include plans to build golf courses and luxury villas in Qatar and the UAE.
President Trump is not currently affiliated with the Trump Organization, having handed over management responsibilities to his children after entering the White House on 20 January.at the beginning of May to develop a Trump-branded luxury 18-hole golf course and a collection of luxury villas north of Qatar's capital, Doha.At the time, Eric Trump said: "We are incredibly proud to expand the Trump brand into Qatar through this exceptional collaboration with Qatari Diar and Dar Global."
Dar Global is a publicly owned Saudi construction company; Qatari Diar is a Qatari state-owned company.Separately, on 30 April,
it would build "the region's first Trump International Hotel & Tower" in the "heart of Dubai" consisting of 80 floors of "luxury living and world-class hospitality".
Eric Trump also visited the UAE recently,"I quite often have to monitor 10 self-checkouts, on my own, whilst two staff cover manual checkouts," they said, adding that there were many customers who steal and try to "con the system".
Gaming developer John O'Reilly, 28, noticed the systems in their local Tesco in Woolwich in south-east London, and wonders how anyone can consent to "such deeply invasive technology".John says that everyone needs groceries so the number of people whose shopping can be tracked is huge.
"Are there even any rules informing customers before they enter? How on earth can the average person understand the extent of the tracking?"Are children even kept out of the dataset? Who can access this data? Is it shared with police? Is my data being sold? We need answers to these questions!"
