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.
Typhimurium) and other non-typhoidal Salmonella are common causes of gastrointestinal infections in people living in industrialized countries. However, in sub-Saharan Africa (SSA), invasive non-typhoidal Salmonella (iNTS) bloodstream infections are common1,2 totalling 3.4 million cases annually, with S. Typhimurium being responsible for approximately two-thirds of these cases. The fatality rate in iNTS can be extremely high3. In SSA, iNTS patients often do not suffer from diarrhoea but instead display symptoms of fever and septicaemia4. There has been no proven zoonotic source of ST313 infections, and human to human transmission has been postulated5,6.
Salmonella food poisoning is normally something that people associate with undercooked chicken or eggs. But The Food Standards Agency (FSA) is reminding the public that eating some types of "pink" lamb or mutton can also pose a risk. Since June, 165 people in England have become ill with Salmonella typhimurium bacteria traced back to meat from affected sheep. Lamb chops and steaks are fine to have pink, but mince isn't, says the FSA. Salmonella typhimurium is one of a group of bacteria that typically live in animal intestines and are shed through faeces.
Salmonella is considered widespread in poultry, and it's perfectly legal for supermarkets to sell raw turkey that has the bacteria. Part of the rationale for allowing salmonella is that people don't eat chicken medium rare, said Timothy Lytton, a Georgia State University law professor. In 1974, a court said that "American housewives and cooks normally are not ignorant and stupid" and that they know how to prepare food so people don't get sick.
