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.
I. INTRODUCTION The basis for effective control of Salmonella infections in poultry production is good farm management and hygienic practices as well as testing and elimination of positive flocks in some countries. While many different measures have been recommended in meat chicken farms, vaccination with live-attenuated vaccines is likely to have a central role in the reduction of Salmonella in commercial operations by increasing the passive immunity of birds and...

I. INTRODUCTION Contamination of eggshells by Salmonella Typhimurium is a major public health and food safety issue to the Australian poultry industry. In Australia, the majority of the egg and egg related foodborne outbreaks are caused by S. Typhimurium (The OzFoodNet Working group 2015). Biofilm formation is one of the survival mechanisms utilised by Salmonella spp. against physical and chemical stress factors in the environment (Steenackers et al. 2012). A biofilm is a...

1. Introduction Eggs and meat from poultry are indispensable protein sources in people's meals in Bangladesh [1]. However, the advancement in the poultry production is often interrupted by the overwhelming occurrence of infectious diseases in low resource settings of developing countries such as Bangladesh. Occurrence of these diseases, which incur a colossal loss due to less production of a quality product and also from the treatment cost, are attributable to noncompliance...

1. Introduction Salmonellosis is among the major causes of foodborne gastrointestinal infection in humans worldwide [1] and the second cause following campylobacteriosis in the European Union (EU) [2]. Particularly, non-typhoidal Salmonella spp. (NTS) are one of the bacterial pathogens with the highest disease burden among human foodborne enteric diseases [3]. Poultry products are considered as a major source of human infection in cases of foodborne salmonellosis caused by NTS [4]....

1. Introduction In Ethiopia, poultry production plays a crucial role in animal agriculture, driven by the growing demand for poultry meat and eggs, which are important sources of protein and income [1,2]. Poultry farming significantly contributes to food security and economic stability [3,4]. However, the poultry industry in Ethiopia is confronted with a complex web of challenges that significantly hinder its productivity and sustainability [4,5]. Chief among these are the...

I. INTRODUCTION Egg-associated Salmonella infection is a significant international public health problem. Internal contamination of eggs with S. Enteritidis has been the principal concern in North America and Europe, whereas external contamination with S. Typhimurium has been the predominant issue in Australia. Some strategies for controlling egg-borne Salmonella are designed to act with precision against epidemiologically important serovars, but others are applicable...

1. Introduction Chickens represent the most widespread source of animal protein that is acceptable for nearly all communities, and, not surprisingly, the highly efficient commercial production of chickens is practised daily worldwide. However, chickens also represent a reservoir of zoonotic agents like Salmonella or Campylobacter. Chickens in commercial production are hatched from disinfected eggs in a clean hatchery environment, despite Gallus gallus being evolved to hatch in...

1. Introduction Salmonella Enteritidis (SE) is one of the most prevalent serovars involved in the contamination of chicken products that cause human infection via the consumption of inadequately cooked chicken meat and eggs [1–4]. Because adult chickens with non-typhoidal Salmonella infection do not exhibit signs of illness, they can remain carriers, releasing the bacteria into the environment through their feces [3]. The poultry industry aims to decrease Salmonella...

I. INTRODUCTION Poultry feed is routinely pelleted for many reasons such as increased feed intake, feed efficiency, and feed hygiene (Abdollahi et al., 2013). However, pelleting is not without its drawbacks, particularly when using higher pelleting temperatures (Abdollahi et al., 2010). The industry has been trending towards ever higher conditioning temperatures due, at least in part, to efforts to improve feed hygiene and thus decrease reliance on in-feed antibiotics for prevention...
