Contact killing of Salmonella Typhimurium by human faecal bacteria

Our gut is home to trillions of bacteria, numbering more than the cells in the rest of our body, and these bacteria help us to digest our food, absorb nutrients and strengthen our immune system. This complex bacterial ecosystem, called the gut microbiota, also helps to prevent bad bacteria from colonising our bodies and making [...]

Assessing a new technique for ensuring fresh produce remains Salmonella-free

Researchers at the Institute of Food Research have tested a new technique to ensure fresh produce is free of bacterial contamination. Plasmas are a mix of highly energetic particles created when gases are excited by an energy source. They can be used to destroy bacteria but as new research shows, some can hide from its [...]

Understanding how bacteria come back from the dead

Salmonella remains a serious cause of food poisoning in the UK and throughout the EU, in part due to its ability to thrive and quickly adapt to the different environments in which it can grow. New research involving a team of IFR scientists, funded by BBSRC, has taken the first detailed look at what Salmonella [...]

Next generation sequencing surveys Salmonella

Strains of Salmonella bacteria cause over a billion cases of illness worldwide each year, and over 500,000 deaths. Most infection occurs through contaminated food and water. As part of the strategy to find ways to reduce the effects of Salmonella, Dr Arthur Thompson and colleagues at the Institute of Food Research have produced the first [...]

Developing innovative processes to ensure fresh food is safe

IFR researchers have recently reviewed the use of cold atmospheric plasmas to inactivate Salmonella to assess their use by fresh or minimally-processed food producers. A growing demand for fresh produce is presenting a challenge to the food industry to supply safe food with minimal processing. It is crucial that these foods are supplied without microbial [...]

Modelling salmonella growth to produce safer pork

Salmonella infections are among the most common bacterial causes of food-borne gastroenteritis in humans, with a number of different potential sources including meat, eggs, and fresh produce. In the EU, up to 20% of human salmonellosis cases are thought to be due to consumption of contaminated pork products.  Most EU countries have established programmes to [...]
