Sal CURB® - The Solution for E. coli & Salmonella in Poultry

Sal CURB®  is a feed acidifier with blended organic acids and surfactants. At zero net cost, the range of Sal CURB products can help layer and breeder farmers achieve complete feed hygiene by reducing E. coli and Salmonella in poultry feed.

Salmonella in Poultry – Also Called Fowl Typhoid or Pullorum Disease   Salmonella in poultry

Salmonella is a common problem in poultry. It is mainly transmitted through animal feed and can cause mortality in birds of any age. As shown by Richardson, reducing Salmonella in poultry feed can lead to a reduction in mortality. Salmonella poisoning can also impact human health.

E.Coli in Poultry E. coli in poultry

E. coli in poultry can cause a number of problems such as Omphalitis (naval infection), Salpingitis (inflammation of oviduct), Cellulitis and Bursitis sternalis. Above all, it leads to a loss in production, bird performance and higher bird mortality. E. coli transmission is from feed and water.

Sal CURB is a feed acidifier that can reduce pathogen load in poultry feed to improve feed hygiene. 

To achieve feed hygiene, what are safe levels of E. coli and Salmonella in poultry feed?


Quality Interpretation

Feed Levels

E. coli (cfu / g)


Less than 1


1 – 10


10 – 100


More than 100

Salmonella should be absent in a 25-gram sample of feed, which means it should not be present in poultry feed at all.

Sometimes it is difficult to detect and quantify Salmonella and E. coli in poultry feed, which can lead to false negative results. To ensure bacteria are detected, it is important to do total Enterobacteriaceae count as well.

How to reduce the Salmonella and E. coli in poultry feed?

Preventing contamination in raw materials, feed milling, transportation, and storage can deliver superior poultry feed hygiene.

1) Raw Materials  
The quality of raw materials determines the quality of the end product, i.e. poultry feed. Raw materials can be treated with an acidifier such as Sal CURB RMS.

2)  Feed Milling 
Milling is an important process in the feed supply chain. It can also be a potent source of Salmonella and E. coli contamination for poultry feed. Feed mill hygiene is important to prevent any contamination at the level of the feed mill.

3) Transportation and Storage 
Using acidifiers in poultry feed can prevent recontamination of the feed during transportation and storage. Sal CURB ASF and Sal CURB Liquid are effective feed acidifiers for superior feed hygiene.

The Sal CURB range of feed acidifier products is effective against Salmonella and E. coli in poultry feed. This can be very effective in breeder and layer feed which is seldom treated with steam.

How Sal CURB® liquid helps in achieving the feed hygiene?

1)  Surfactant Technology 
The surfactant helps in reducing the surface tension of the water and thereby facilitating the spread of active ingredient over the feed matrix. The surfactant also helps in penetration of lipophilic outer membrane of the microbes. Through this surfactant technology, Sal CURB delivers superior feed hygiene. 

2) Blend of Organic Acids  
The mindful blending of short chain organic acids is pre-requisite for a superior feed acidifier. The blend is designed to have a complete action against Salmonella and E. coli in poultry feed. 

Look beyond normal acidifiers in poultry feed and use Sal CURB for superior feed hygiene. For more information on feed hygiene please contact a Kemin representative.
