Flavoured noodle products are the most likely source of the ongoing multi-country Salmonella Stanley outbreak; there is evidence linking the cases to products of the same brand, according to a rapid assessment of the outbreak conducted by the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC). The same bodies have, however, identified some alfalfa sprouts as the possible origin of a multi-country outbreak of Salmonella Bovismorbificans.

With regard to the first outbreak, between November 2025 and June 2026, 106 confirmed cases were reported in 13 Member States of the European Union or the European Economic Area and in the United Kingdom. The outbreak mainly affected children and young adults, and at least 49 people had to be hospitalised. Cases have been reported in Austria, the Czech Republic, Denmark, Estonia, France, Germany, Hungary, Latvia, Lithuania, the Netherlands, Norway, Poland, Sweden and the United Kingdom.

As for the second, however, between January and May 2026, 109 confirmed cases were reported in 10 countries of the European Union or the European Economic Area and in the United Kingdom. In this case, the countries concerned are Austria, Belgium, the Czech Republic, Denmark, Finland, Germany, Ireland, Luxembourg, Spain, the Netherlands and the United Kingdom. Most of the cases involved adults, mostly women. Eighteen people required hospitalisation, and one death was reported among the confirmed cases.
