Albert Heijn already recalled snacks and Easter cakes on Monday.
The cookies in question are made by the Merba manufacturer from Oosterhout in Brabant. Just like last week, the metal fragments were too small to be detected by the plant's detectors, it reported Tuesday.
“The metal particles found have different sizes, and are mainly thin and long, which poses a potential risk to human health if consumed,” Merba said.
Albert Heijn, Jumbo, Dirk, PLUS, Spar, Boni, Coop, Hoogvliet, Vomar and DekaMarkt removed chocolate biscuits from shelves last week due to metal particles. HEMA also warns about the presence of metal particles in its chocolate chip cookies.
Cookies were also delivered abroad. In Belgium, chains Delhaize, Colruyt, ALDI and OKay are removing chocolate biscuits from shelves due to metal particles, food watchdog FAVV reports.
It is unknown how these flakes ended up in the cookies.
