Researchers from McMaster University in Canada have developed a simple and inexpensive method that helps to detect Salmonella typhimurium in few time. The authors indicated that this method could be practical in poultry processing plants and food preparers.

The research is called A Simple Colorimetric Au-on-Au Tip Sensor with a New Functional Nucleic Acid Probe for Food-borne Pathogen Salmonella Typhimurium and was published in the Angewandte Chemie.

This study relies on the importance of Salmonella on public health and the global economic consequences of this microorganism due to the expenses related to health care both in animals and humans, management practices, biosecurity, detection methods, food waste, etc.

The Centers for Disease Control and Prevention has estimated 450 deaths, 23,000 hospitalizations, and $365 million in direct medical costs per year due to Salmonella disease in the United States. However, it could be specifically most associated with Salmonella Typhimurium due to the strong resistance in the environment and fast reproduction of that strain.
