By treating feed and feed storage bins with organic acids, poultry producers in the UK can reduce the risk of Salmonella contamination in their flocks.
The application can also help poultry producers to comply with the recently implemented National Salmonella Control Programme, reports Farming UK.
In 2005, 8% of UK flocks were infected with Salmonella. The National Salmonella Control Programme aims to reduce this by 10% by 2010. As from 1 January, eggs from Salmonella-positive flocks had to be excluded from the food chain.
"Salmonella is principally spread by several main vectors and poultry producers need to take steps to reduce all possible risks," said Richard Scragg from Optivite. "This will include improving biosecurity and possibly vaccination, but treating feed is another effective control measure."
Poultry and livestock feed is known to be a possible route by which Salmonella can enter the food chain, so treatment of feed as well as feed storage areas with organic acids can be an effective control measure. Organic acids have a powerful antimicrobial effect and can significantly reduce Salmonella infection levels while not presenting antibiotic resistance issues, reports state.
Salgard, which is a blend of organic acid salts, is a possible option. This can be applied to feed ingredients, incorporated in pelletted feeds or added to feed as it is blown into a storage bin. The organic acids have a powerful anti-bacterial and anti-fungal effect and 50% of Salmonella organisms are killed within an hour with full potency achieved in 24 hours, states Optivite.
