Salmonella Outbreak: Study Reveals High Rate of Infection in Indonesian Fish Samples

Strategic Insights

— 1 min read

Recent research has highlighted a concerning rate of Salmonella infection in fish samples from the Pahandut Seberang River in Indonesia. The study, conducted by Universitas Palangka Raya researchers, found that all 14 water, tilapia, and catfish samples tested positive for Salmonella sp. bacteria. This alarming discovery raises concerns about the safety of fish consumed in Indonesia, where a significant number of people rely on fish as a primary source of protein.

Key Takeaways:

  • The study found that 100% of water samples, tilapia, and catfish tested positive for Salmonella sp. bacteria.
  • The detection of Salmonella sp. was confirmed through selective media Salmonella Shigella Agar (SSA) and gram staining tests.
  • 5 samples (B N1, C N2-3, B L1, and B N2-3) were found to have Salmonella paratyphoid B bacteria, while 9 samples had Salmonella typhi bacteria.
  • All samples exceeded the Indonesian National Standardization Agency's SNI 7388:2009 maximum level of microbial contamination.
  • The study concluded that the tilapia and catfish samples did not meet the required standards for food safety.
  • According to the Institute for Health Metrics and Evaluation, the global rate of salmonellosis in 2019 was 4.22 cases per 100,000 people, with a 1.72 fatality rate.

Statistics:

  • 100% of water, tilapia, and catfish samples tested positive for Salmonella sp. bacteria.
  • 5 samples (B N1, C N2-3, B L1, and B N2-3) had Salmonella paratyphoid B bacteria.
  • 9 samples had Salmonella typhi bacteria.
  • The global rate of salmonellosis in 2019 was 4.22 cases per 100,000 people.
  • The fatality rate for salmonellosis in 2019 was 1.72%.
  • The mortality rate in Indonesia in 2019 was 2.42 and 5.82 per 100,000 people.
