Salmonella in poultry
Poultry can become infected with many different types of salmonella; about 10 percent of all Salmonella spp. have been detected in poultry. The most important are Salmonella Typhimurium and Salmonella Enteritidis. Other serotypes frequently occurring in poultry worldwide are, for example, Salmonella Hadar, Salmonella Livingstone, and Salmonella Senftenberg. In most cases, the birds are not sick and the production is not affected. The degree of illness depends on factors of both the bacteria and the host. The bacterium’s serotype and phage type is of significance but also the type of animal, age and general health status. S.Typhimurium and S. Enteritidis may induce clinical symptoms in poultry. It is mainly in very young chickens aged up to two weeks that salmonella can cause disease and death. The symptoms may vary and include weakness, loss of appetite and poor growth. The animals are crowded close to heat sources and sit with drooping wings and their eyes closed.
A decrease in eggshell quality is a trait that may be used to detect chickens infected with Salmonella, according to recent US research.
ARS (Agricultural Research Service) veterinary medical officer, Jean Guard Bouldin, found an interesting phenomenon - not only was Salmonella present inside chicken eggs, but other bacteria were there also.
Since these bacteria are usually seen in eggs that have been contaminated through cracks in the shell, Bouldin theorized that poor eggshell quality...

USDA's Food Safety & Inspection Service is making available results of baseline studies it conducted on generic E. coli and salmonella between 1997 and 2000 as a means to assist inspected establishments in assessing their progress on testing to meet performance criteria.
FSIS stressed that publication of the baseline results does not affect the current generic E. coli criteria and salmonella standards listed in FSIS regulations. The regulations require that all inspected meat and poultry...

Javier Ochoa Repáraz defended his PhD thesis at the University of Navarre Faculty of Science on the development of an acellular vaccine aginst Salmonella enteritidis.
This involves a world pandemia considered to be the most importante zoonosis or illness/infection transmissible salmonellosis by animals to humans under natural conditions. It is estimated that the incidence of acute worldwide is more than a thousand million cases per annum and causes three million deaths.
The project...

The European Food Safety Authority (EFSA) wants a more sophisticated use of vaccines in preventing salmonella in poultrymeat and egg production.
A complex set of guidelines says its usefulness and safety depends on whether disease reduction or eradication is being sought, the type of poultry, production stage, cost-benefit and other issues. One key is ensuring vaccinations are not passed onto humans, lessening their potency....

The United States Department of Agriculture (USDA) has approved FreshFx® antimicrobial solution for On-Line Reprocessing (OLR) of poultry carcasses, giving commercial poultry processors the only non-toxic alternative to noxious chemicals currently being used for OLR, as well as being easy-to-use and extremely cost-effective. The use of FreshFx for OLR significantly reduces Salmonella and Escherichia coli (E. coli) on poultry carcasses when compared to those processed traditionally.
The...

Egg producers should take steps to ensure that their flocks are protected against salmonella infection right through to the end of lay.
"We have been informed that an EU salmonella survey means that faeces/dust samples will be collected rom flocks approaching the end of production," Matthias Mangels, Lohmann Animal Health's head of vaccine sales, told egg producers in Shropshire.
He said that the industry was doing a good job in controlling salmonella. Human cases of salmonella PT4 (the...
