Le Hello et al., (2012) Emerging Inf Dis 18: 132-134

This study reports a food-related outbreak of salmonellosis in humans caused by a nonmotile variant of Salmonella enterica serotype Typhimurium in France in 2009. This variant genetically distinct from the emerging monophasic  variant described worldwide, has been circulating in laying hens, whose contaminated eggs had likely caused food poisoning (homemade tiramisu prepared with raw eggs).
This nonmotile variant had been circulating in laying hens but was not considered as Typhimurium and consequently escaped European poultry flock regulations.
