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.
Dr. Ioannis Mavromatis, MEA Technical Sales Consultant for Calier, explores how Salmonella threatens poultry producers in the Middle East and North Africa. He discusses its impact on human health, farm contamination, and the role of vaccination, biosecurity, and farm management in controlling outbreaks....

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...

Introduction Animal husbandry, the agricultural practice of breeding and raising livestock, is a major food-producing industry worldwide. The increasing global demand for animal protein results in rapidly growing animal production as well as the growth of animal feed and the feed additive market. The feed additives have played a significant role in the sustainability of the livestock industry. There are four major drivers for the growth of the animal feed additive market including:...

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...

INTRODUCTION Foodborne infections caused by Salmonella enterica are of primary importance worldwide. The WHO estimates that Salmonella causes more than 153 million illnesses, 120,281 deaths, and 8.27 million disability-adjusted life years annually (1). As foodstuffs can be contaminated in several parts of the food chain, a “from farm to table” approach is necessary to understand the epidemiology of Salmonella. Although Salmonella can contaminate vegetables, food-producing...

Recent data from the European Food Safety Authority (EFSA) indicated that 95.6% of the Salmonella isolates in broiler flocks belong to the Infantis serovar, demonstrating a close association with poultry production [2]. In recent years, the increasing incidence of S. Infantis infections in both humans...

INTRODUCTION Non-typhoidal Salmonella (NTS) enterica subsp. enterica is a foodborne pathogen that causes »1.2 million infections in the United States of America (USA) annually (Scallan et al., 2011), and was responsible for more than 95 million cases of diarrheal disease and 50,771 deaths worldwide in 2017 (Stanaway et al., 2019). Human infections are usually mild and manifest as a self-limiting gastroenteritis. However, high-risk populations such as the infants, the elderly,...

Nontyphoidal Salmonella (NTS) represents one of the leading causes of foodborne gastroenteritis worldwide (1, 2). The global burden of NTS infections is 93.8 million cases, and it is estimated that NTS causes around 155,000 deaths annually (3). Unfortunately, there is a lack of information about surveillance studies of NTS in Latin American countries, and reports on NTS outbreaks are scarce in this region (4). In South American countries, there has been an increase in reports of...

I. INTRODUCTION Mycotoxins are secondary metabolites produced by fungi (fusarium, aspergillus, penicillium mainly) that can cause serious health problems in poultry and may result in severe economic losses. They can exert negative impact on both performance (Kolawole et al, 2020) and intestinal health (Antonissen et al, 2014) depending on the type of mycotoxin, extent of exposure, its concentration, the age of the animals and their health status. Mycotoxins can also be a predisposing...
