bna = not analyzed; EHEC = enterohaemorrhagic Escherichia coli; EIEC = enteroinvasive E. coli; EPEC = enteropathogenic E. coli; ETEC = enterotoxigenic E. coli.
cIn two of the incidents, two (caliciviruses and EHEC) and three agents (calicivirus, ETEC, and rotaviruses), respectively, were detected in feces samples, and in two other incidents, two agents (E. coli and B. cereus, and S. aureus and B. cereus, respectively) were detected in food samples.
dRefers ti generic E. coli. No further characterization was done.
eSalmonella Enteritidis (phage type 21).
fIn the largest incident (93 cases), disease agents other than S. aureus may have been involved since atypically long incubation times were recorded for some of the cases.
gSum minus negative does not equal the number of positive samples since two or more agents were detected in some samples. See footnote c.
