Listeria Microbiological Testing
Ensuring food safety through Listeria testing and prevention solutions.
Listeria is a group of bacteria consisting of 20 species, of which L. monocytogenes is pathogenic. Unlike many other common foodborne diseases causing bacteria, L. monocytogenes can survive and multiply at low temperatures usually found in refrigerators.
Listeria is known to be found in all environments and is known to proliferate at a wide range of temperatures. Listeria monocytogenes causes an illness called Listeriosis. Cases of listeriosis from food are rare but it has a high mortality rate, especially with the immune-suppressed, the elderly or pregnant women.
Food sources often linked with Listeriosis are:
- Unpasteurised milks
- Products made from unpasteurised milk
- Soft cheeses
- Ready-to-eat foods including pre- packed sandwiches, pate and sliced meat
