Clearly, ice-creamwas the incriminated food vehicle of the outbreak
as neither CPS nor SEs were detectable in any of the other food
remnants. Ice-cream has regularly been involved in SFP outbreaks in
the past (Enhuber, 1971; Seidel et al., 1962), and not just in Germany
(Williams and Swift, 1946). By far themost common cause of staphylococcal
food poisoning worldwide is SEA (Argudin et al., 2010). This was
also the case in the present outbreak with findings of enterotoxin A on
pheno- and genotypic level among S. aureus strains from human cases
and food left-overs
