AP Update:  The Netherlands’ National Institute for Public Health and the Environment said the salmon has been traced to the Dutch company Foppen, which sells fish to many major Dutch supermarkets and to stores around the world, including the United States.  The institute said in a statement that around 200 people — and likely more — in the Netherlands and more than 100 people in the United States have been sickened by a strain of the bacteria called Salmonella Thompson.

Harald Wychgel, a spokesman for the Dutch public health institute, said the institute got its information on Americans becoming ill from the U.S. Centers for Disease Control and Prevention.  However, a representative for the CDC said the agency was investigating and had not confirmed any illnesses.

Costco Wholesale Corp., which sold the salmon in the U.S., said it had no reports of illness.

Barfblog, the BBC, Expatica and AFP report that hundreds of consumers in the Netherlands and the United States have been sickened by Salmonella after eating smoked salmon produced by Dutch fish factory, Foppen.  In the Netherlands “some 200 people have fallen ill through contaminated salmon” while in the US about 100 people were infected “by the same type of Salmonella”, said the National Institute for Public Health (RIVM) in the Netherlands.

“The real number of infected people is likely to be higher,” the RIVM added in a statement, saying smoked salmon made by Dutch fish producer Foppen has been taken off the shelves and removed from storage fridges.  Foppen supplies smoked salmon to major supermarket chains including retail giant Albert Heijn, Dutch food and consumer watchdog NVWA said in a statement.  It warned consumers not to eat any Foppen salmon already bought at supermarkets, which had been advised to take the product off their shelves.

“An international recall is being prepared,” the RIVM added, referring to salmon sold in the United States.  The NVWA rang alarm bells Friday, issuing a recall and advising consumers not to eat smoked salmon produced by Foppen.
