FAO publication of GBS ST283 in freshwater fish Risk Profile and Factsheet


In Singapore during 2015, Group B Streptococcus (GBS) sequence type 283 (ST283) caused the only reported foodborne outbreak of invasive GBS disease. Over 20 percent of cases were healthy adults without comorbidities, which is unusual for GBS. The outbreak was linked to the consumption of raw freshwater fish. Subsequent investigations found that ST283 GBS has been common among GBS causing disease in humans and in tilapia across Southeast Asia for at least 20 years whereas it was almost non-existent outside this region. Given the novelty of the outbreak, this risk profile consolidates the current knowledge to identify data gaps about GBS ST283 along the freshwater fish supply chain in Southeast Asia.
Professor of Veterinary Epidemiology Dr. Kohei Makita at Rakuno Gakuen University was involved in this risk profiling as an expert of risk analysis. The risk profile and factsheet can be accessed from below URL.
