A costly approach to control pig infection with Salmonella Typhimurium
The use of acids to control Salmonella Typhimurium is widespread. This treatment may even prevent the shedding of Salmonella. But acids as Salmonella treatment cannot prevent infection and organ colonization with Salmonella.
In addition, pig infection with Salmonella can occur at any time: while still a suckling piglet, during nursery, in the fattening unit, and even during transportation to the slaughterhouse or when in the lairage. Acids do not protect against infection in these situations.
Once a pig is infected with Salmonella and it is harbored in its lymph nodes, shedding can reactivate very quickly. The risk of infection with Salmonella Typhimurium is especially high when the pig is under stress, such as during the transition period, and when the concentration of acids in the feed or drinking water is low – a common circumstance as farmers tend to use less acid because of its high costs. The consequence: Salmonella shedding increases and initial problems return.
A cost-efficient approach to control pig infection
Only vaccination with an attenuated live vaccine significantly reduces the lymph nodes of a pig from being colonized with Salmonella. Therefore, vaccination is reliable, sustainable and more cost efficient. Salmonella vaccination reduces:
- pathogen excretion
- organ colonization with Salmonella
- clinical symptoms
- presumably costs
Acid Costs for Salmonella Treatment

A Simple Calculation:
Yearly Salmonella Vaccination Costs Versus Acid Costs
Calculate* your possible Salmonella vaccination costs in comparison to the costs of an effective treatment with acids (either 98% benzoic acid or 80% mix of formic / lactic / sorbic acid) during nursery and fattening. Simply insert the numbers of your farm in the table below and your savings will be automatically calculated (preset comparison: benzoic acid).
Annual savings 0.00 €
Salmonella vaccination costs: 0.00 €
Acid treatment costs: 0.00 €
1 Given: a nursery pig eats approx. 41.9 kg feed and there are 6 AIAO groups; a fattening pig eats approx. 270 kg feed and there are 3 AIAO groups
2 Piglet feed usually already contains 0.2 – 0.3% acid on delivery
3 Salmonella vaccination costs for sows are tripled; for piglets are doubled (change for piglets in calculator if necessary)
