Objectives: To identify the source and intervention methods for an outbreak
of Salmonella Typhimurium phage type 12 in South Australia.
Method: Ten cases of S. Typhimurium phage type (PT) 12 infection were notif
ied in South Australia in a four-week period from 7 May 1998. Nine cases an
d 27 controls were included in a case control study to test the hypothesis
that illness was associated with the consumption of chicken nuggets.
Results: A significant association between illness and the consumption of o
ne brand of chicken nuggets was determined, odds ratio undefined (95% CI un
defined; p = undefined). Nine of nine cases and one of 27 controls reported
eating these chicken nuggets. S. Typhimurium PT 12 was isolated from an op
ened sample of this particular brand of nuggets which had been retrieved fr
om the home of one case.
Conclusions and implications: The implicated nuggets were essentially a raw
product which had been 'flash fried' in contrast with other brands which w
ere fully cooked. The investigation highlighted issues of inadequate labell
ing and consumer responses to labelling information which affect food safet
y. A media release to highlight to the consumer the need to cook frozen foo
d properly and a voluntary recall of the 'flash fried' product was instigat
ed as a result of these conclusions. Further action is needed to eliminate
the potential hazard that consumers will perceive and handle 'flash fried'
nuggets as if they are a cooked chicken product.
