Choreographed stages of Salmonella infection revealed by Liverpool scientists

(University of Liverpool 11 December 2013) Scientists have used a new method to map the response of every salmonella gene to conditions in the human body, providing new insight into how the bacteria triggers infection.

Why are we more scared of raw egg than reheated rice?

BBC News Lucy Townsend 2 December 2013

Twenty-five years ago minister Edwina Currie sparked a scare over salmonella in eggs and had to resign amid outrage from farmers and plummeting sales. The panic has shaped the way we think about food safety.

There are foods that people instinctively associate with the risk of poisoning – raw chicken, raw egg, shellfish.

At the time of Edwina Currie’s remarks – which were perceived to have dramatically exaggerated the prevalence of the disease in eggs in the UK – there were 12,302 cases of the salmonella PT4 strand most commonly found in poultry.

It dropped by 54% in the three years following the introduction of the British Lion scheme in 1998, which saw hens vaccinated against salmonella, and last year there were just 229 reported cases.

But people are still mistrustful.

Woman dies after Melbourne Cup salmonella outbreak

Brisbane Times Amy Remeikis November 14, 2013

A batch of bad eggs has been blamed for a salmonella outbreak linked to the death of one elderly woman and sickness in hundreds of others.
At least 220 people have reported being sick and a 77-year-old woman’s death has been linked to the food poisoning outbreak.
Included among those 220 people were 11 departmental staff members from the office of Premier and Cabinet.

One dead, 200 ill after salmonella outbreak linked to Melbourne Cup functions

News.com.au November 14, 2013

A 77-year-old woman has died and at least 220 people have reported falling ill amid a widespread outbreak of salmonella poisoning linked to a series of Melbourne Cup functions.
Queensland Health is investigating whether a Brisbane catering company was responsible for the outbreak.
The company is understood to have catered for up to 40 Melbourne Cup functions attended by people who later became ill.
About 700 people could have been exposed by attending the functions affected.
Metro North public health unit director Susan Vlack said an investigation was underway into whether salmonella was a contributing factor in the elderly woman’s death.

Salmonella sensing system

(American Institute of Physics 18 October 2013) Foodborne illnesses spread easily and, as such, are a difficult-to-control problem — even more so in developing nations. Quick detection can play a critical role in halting the spread of contamination. Traditional detection methods, however, tend to be haltingly slow. Recognizing the need for a real-time biosensing system to detect pathogenic bacteria, a team at Auburn University came up with a novel design, which they describe in the AIP’s Journal of Applied Physics.

Device speeds concentration step in food-pathogen detection

EurekAlert 14 October 2013

Researchers have developed a system that concentrates foodborne salmonella and other pathogens faster than conventional methods by using hollow thread-like fibers that filter out the cells, representing a potential new tool for speedier detection. The machine, called a continuous cell concentration device, could make it possible to routinely analyze food or water samples to screen for pathogens within a single work shift at food processing plants.
