Scientists Use Machine Learning to Find Source of Salmonella

Scientists at the University of Georgia Center for Food Safety has developed a new approach to identify the animal source of some types of Salmonella outbreaks. The researchers have developed a machine learning approach. The study is published in the January 2019 issue of Emerging Infectious Diseases. Researchers Xiangyu Deng and Shaokang Zhang, along with a team of colleagues, used more than a thousand genomes to predict the animal sources of Salmonella Typhimurium. The project used experts from the Centers for Disease Control and Prevention, the Food & Drug Administration, the Minnesota Department of Health, and the Translational Genomics Research Institute. Almost 3,000 outbreaks of food poisoning were reported in the U.S. from 2009 to 2015. Ninety percent of those … [Read more...]

Decline in Europe’s Salmonella Cases Stalls, with More Illnesses Linked to Eggs

Europe has been wining the battle against Salmonella infections, but that decade-long decline ended last year. A small increase in Salmonella illnesses linked to eggs and egg products was reported in 2016. The European Centre for Disease Prevention and Control and the European Food Safety Authority issued a joint report yesterday about this issue. The report covers foodborne illnesses from 28 European Union member states and 9 other countries. There were 4,786 foodborne illness outbreaks for the year, which is a slight increase from 2015. And unfortunately, Campylobacter and Listeria monocytogenes outbreaks increased. Salmonella Enteritidis infections in people increased by 3% since 2014. This number parallels the increase in the number of laying hens over the same time period. … [Read more...]
