Recent cases of food poisoning (in 2019) due to Salmonella and Listeria show that appeared in the media have highlighted the importance of the control and analysis of pathogens (Listeria monocytogenes and Salmonella) and the consequences for consumers and companies in the food sector. They have been serious cases, like 5 dead from eating sandwiches in the hospital in the UK, 5 dead by consuming trout and smoked salmon or French Government stopped the production of a cheese company after finding Listeria in their products.
The new MicroLab device can detect the presence of Salmonella or Listeria in food samples in a simple and safe manner. The new system integrates all the assay steps into a single disposable device. It facilitates and speeds up the results while minimizing production losses in case of contamination.
Listeria is a Gram-positive bacillus genus in which Listeria monocytogenes appears to be the only human foodborne pathogen specie. The infectious disease associated with Listeria monocytogenes is potentially mortal. Its riskiness is related to the ubiquitous presence of the bacteria in the environment and its growth capacity at low temperature and high salinity. Despite having listeriosis a low incidence (normally less that one in 100,000 people per year) the mortality rate appears to be around 20-30%.
According to the latest EFSA (European Food Safety Authority) report published in 2014 and referred to the 2012 year, there were 1,642 confirmed human cases of listeriosis in the European Union which corresponds to 10.5% increase compared with 2011. The highest notification rates were produced in Finland, Spain and Denmark with Romania representing the lowest notification rate. Almost all the cases were from domestic origin.
