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.
We have a constant dilemma and ask for help. If hens in the feces determine the presence of Salmonella enteritidis without having tons of chicken shows no signs of the disease, what is the likelihood that it will be in eggs and chickens found this bacteria? ...

The poultry industry is one of the most important sectors of the Brazilian agribusiness. In addition of being extremely important for economy due to the billions of dollars generated by exports, the poultry industry has a very relevant social role as it employs thousands of people all over the country. Global exports of chicken meat increased 11.4% in 2007, with 7.2 million metric tons (MT). Brazil had a 45% share in this international market,...

I. INTRODUCTION Food borne illness costs Australia an estimated $1.2 billion per year (Hall et al., 2005). The annual report of the OzFoodnet network (2009) reported 9,533 cases of Salmonella infection. Although the eggs produced in Australia are of good quality, the egg industry is often blamed for cases of food poisoning due to Salmonellosis. Salmonellosis can be acquired by the ingestion of raw or undercooked eggs. As well, cross contamination...

Poultry CRC researcher, Dr Kapil Chousalkar at The University of Adelaide, has recently commenced a project investigating the dynamics of Salmonella shedding on commercial cage layer farms. Titled Epidemiology of Salmonella on layer farms , this research aims to determine the roles environmental, or bird or egg factors play in the transmission pathways of Salmonella species. “This will answer...

Breeding In the U.S., vaccines are the most commonly used approach to eliminating Salmonella in breeder chickens. In the E.U., Denmark, Finland, The Netherlands, and Sweden have taken the approach that if a breeder flock is positive for Salmonella, they slaughter the flock. This is cost preclusive in the U.S. due to the scale of the industry. The E. U. in general use vaccination and/or competitive exclusion as a...

Part III- Simple strategies to avoid Salmonella outbreaks Salmonella is a pernicious pathogen and eradicating it entirely from the food chain is difficult. Despite our best efforts to eradicate it from the food chain, it can still cause expensive and devastating losses - of productivity and of human life. Yet another case of human salmonellosis has been reported in the US recently,...

New federal regulations require most egg producers to take steps to prevent the spread of Salmonella enteritidis, reports the American Veterinary Medical Association. The FDA rules affect the purchase of chicks and young hens, sanitation in production facilities, testing for the bacteria, and storage of eggs at farms with at least 3,000 laying hens. An FDA announcement states the rules are expected to reduce the number of S enteritidis infections by 60%, preventing about 79,000 cases of...
