Why this research matters now
The report provides evidence relevant to investigating food-associated gastroenteritis outbreaks by combining exposure information, product trace-back, and laboratory findings to identify a common implicated food batch.
Structured evidence summary
Research question
The report investigated whether imported frozen raspberries from a shared batch were associated with a cluster of norovirus outbreaks in Southern Finland.
Study design
This was an outbreak investigation using epidemiological, trace-back, and laboratory investigations, including relative-risk analysis and norovirus testing with partial capsid sequence comparison.
Population and setting
The investigation concerned about 200 people affected in Southern Finland during September and October 2009. Exposures occurred in separate catering settings and a daycare center, where raspberry-containing foods were served.
Main findings
Norovirus genotype GI.4 was detected in frozen raspberries and in samples from two patients, with identical partial capsid sequences reported between the patient and berry samples. At the daycare center, consumption of the berry dish was associated with a relative risk of 3.0, and the investigation concluded that one raspberry batch was the source of the outbreaks.
Public-health relevance
The report provides evidence relevant to investigating food-associated gastroenteritis outbreaks by combining exposure information, product trace-back, and laboratory findings to identify a common implicated food batch.
Important limitations
The summary is limited to the supplied single-article abstract and metadata; the original paper is required for decision-grade interpretation of the methods, analyses, sampling, and uncertainty.
GIDS interpretation
The article is discoverable as evidence concerning norovirus-associated gastroenteritis, foodborne outbreak investigation, Finland, and surveillance-related work. This classification provides context for retrieval and review but does not establish a connection to any live surveillance signal.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
