Sci-Tech validates Salmonella vaccine differentiation test
11th October 2022Sci-Tech has successfully validated a poultry vaccine differentiation test for Salmonella Enteritidis. This new service allows vets and poultry farmers to distinguish between wild and vaccine strains of Salmonella Enteritidis, helping farmers maintain compliance with the Lion Code and protect public health.
‘Salmonella vaccination is mandated for poultry farmers because of the potential threat to food safety,’ said David Petrie-Dolphin, Business Development Manager at Sci-Tech. ‘All eggs sold in supermarkets must be stamped with the Lion Code to show that they have been produced to the highest possible standards. To get this stamp, they need to adhere to all requirements of the Lion Code.
‘As part of the required Salmonella test, we are able to detect the presence of Salmonella Enteritidis and determine whether the strain is vaccinal or wild,’ David continued. ‘If no Salmonella is found, or the strain is vaccinal, then the farmer can continue to trade. If a wild strain is identified, then the farmer will have to get rid of the current batch and start over. So, our vaccine differentiation test helps them save time and money whilst safeguarding public health.’
The test detects the Salmonella Enteritidis vaccine using a chromogenic reaction. Any samples that have a positive Salmonella Enteritidis result can be further screened in the laboratory for differentiation. The new test is highly beneficial for Salmonella surveillance, as it confirms the presence of the vaccine strain for the CEVA Salmovac vaccine. Results are available within 48 hours to allow potential action to be taken as quickly as possible.
‘At Cawood, we are committed to helping our customers meet their goals whilst maintaining compliance. Developing and validating new solutions is a big part of this,’ said Sean Stevenson, Divisional Managing Director for Cawood Agriculture. ‘It also helps us further cement our position as the UK’s leading scientific group, supporting a safer, healthier planet.’
