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.
INTRODUCTION Poultry and poultry products represent a popular choice of protein in the United States, with increasingly high consumption rates over the past years (Zhang et al., 2018). Poultry meat has surpassed both pork and beef in per capita consumption in the United States (USDA Economic Research Service, 2020). With this increased consumption of poultry and poultry products, there is a significant concern for contamination, thus impacting public health. Salmonella and...

Introduction Conventional systems (battery cages) lead commercial egg production worldwide due to their reportedly efficient disease prevention processes (WHILEY; ROSS, 2015). However, shifts in egg consumption have drawn attention to potential animal welfare issues and generated demand for alternative laying systems with improved hen wellbeing. In this way, free-range systems could be an ideal choice for egg production and hen welfare (JONES at al., 2012); however, despite...

The Food Safety and Inspection Service (FSIS) is considering a regulatory framework for a new strategy to control Salmonella in poultry products and more effectively reduce foodborne Salmonella infections linked to these products. The framework under consideration has been shaped by months of information-gathering and discussions with a wide range of stakeholders, researchers, and scientists.
At the same time, FSIS is gathering scientific evidence relevant to the approaches presented...

INTRODUCTION Salmonella and Campylobacter continue to be pathogens of concern associated with poultry and poultry products, which raise a public health issue globally (Antunes et al., 2016). As per the foodborne illness source estimation reports for 2016, Salmonella and Campylobacter are responsible for about 18 and 64% of poultry-related foodborne illnesses in the United States, respectively (IFSAC, 2018). With the increasing episodes of illnesses because of these pathogens,...

INTRODUCTION Consumption of poultry meat has increased significantly in the United States and currently ranks as the highest consumed among meat species (National Chicken Council, 2020). With increasing chicken meat consumption, greater number of broilers are being raised and processed. Foodborne pathogens Salmonella and Campylobacter are commensals in broiler gastrointestinal tract and, in most cases, do not cause any disease in the birds. Current poultry processing system...

1. INTRODUCTION Salmonella enterica subsp. enterica is the most common cause of foodborne human gastroenteritis, a disease characterised by gut inflammation and self-limiting diarrhoea in humans (Winter et al., 2010). It is estimated that gastroenteritis caused by Salmonella spp. accounts for 93.8 million human cases worldwide each year (Majowicz et al., 2010). Worldwide, contaminated food products of animal origin, particularly egg and egg products, are...

I. INTRODUCTION Over the past few decades the meat, egg and milk sectors have faced the need to reduce the routine use of antibiotics in animal production, and the high incidence of food poisoning associated with animal product consumption. Approximately 130,000 tonnes of antibiotics were used in 2013 worldwide, with 75% of this in animals (Hughes, 2019). Up to 90% of these antibiotics can be excreted into the environment via urine and faeces, and approximately 400 resistance...

I. EPIDEMIOLOGY OF SALMONELLA INFECTIONS Most Salmonella strains belong to non-host specific or broad-host range serotypes, and thus can colonize the gut of many animal species, including humans. In contrast to host-specific serotypes that cause septicemia and severe disease (typhoidal serotypes), the broad-host range serotypes are asymptomatically colonising the host in most cases, but can cause diarrhoea when high numbers of bacteria are orally take up at once, as is...

DESCRIPTION OF THE PROBLEM In the United States, foodborne nontyphoidal salmonellosis affects approximately one million individuals, results in 378 deaths and costs approximately $3.3 billion USD annually (Scallan et al., 2011). Most of these infections are associated with animal meat and product consumption, with poultry or poultry products being the major source (Marin and Lainez, 2009). Therefore, eradication of Salmonella in the production cycle of poultry and in processing...

Poultry farms act as an important source of transmission of antimicrobial-resistant (AMR) Salmonella to the environment as well as to humans. Indiscriminate and prophylactic use of antibiotics in poultry farms is one of the reasons behind it. Therefore, a cross-sectional study was conducted to determine the prevalence of Salmonella in broiler chickens, farm environments, as well as farmers to identify the risk factors for Salmonella colonization in broiler farms....
