Food Safety News

More than 120 people are part of a multi-country Salmonella outbreak linked to Brazil nuts.

Since August 2019, the outbreak, caused by Salmonella Typhimurium and Salmonella Anatum, has affected three European Union countries, the United Kingdom and Canada. The United States was one of more than 30 countries that received Brazil nuts from Bolivia contaminated with Salmonella.

In total, 123 cases of Salmonella Typhimurium have been reported, of which 105 were in the UK, 14 in France, three in Luxembourg and one each in the Netherlands and Canada. One Salmonella Anatum patient was recorded in the UK.

A case-control study in the UK and patient interviews in the UK, France and Luxembourg indicated Brazil nuts and nut bars as likely vehicles of infections. Two batches of Brazil nuts from Bolivia tested positive for Salmonella Typhimurium and Salmonella Anatum matching the outbreak strains.
