Poultry biosecurity
Biosecurity is a key management tool and an essential part of any successful poultry production system: it can be defined as the planning and implementation of a set of measures to protect domestic poultry flocks against the introduction of unwanted organisms. Because of the concentration in size and location of poultry flocks in current commercial production operations and the inherent disease risks associated with this type of production, it is imperative that poultry producers practice daily biosecurity measures. Developing and practicing daily biosecurity procedures as best management practices on poultry farms will reduce the possibility of introducing infectious diseases such as Avian Influenza and Exotic Newcastle as well as many others. Contract poultry growers should be familiar with the specifics of their company’s biosecurity protocols and work closely with company representatives to implement those programs.

South American countries such as Argentina, Chile, Brazil, Paraguay, Peru, and Uruguay reported the detection of HPAIV H5N1 clade 2.3.4.4 b in domestic and wild birds for the first time in the region from the end of 2022 to the beginning of 2023. Human infections were reported for the first time in South America, Ecuador, and Chile. Since October 2022, the PREVIR-MCTI network, a Brazilian network for virus surveillance in wild animals, has been collecting samples from asymptomatic wild...

The emergence of highly pathogenic H5N1 avian influenza poses a significant threat to human and animal health worldwide. This summary provides an overview of the surveillance efforts implemented in Peru to combat the spread of H5N1 avian influenza. Joint efforts between the authority, the productive sector, and academia date back to the first influenza outbreak in Chile in 2002. Since then, the government has been developing intense clinical and serological surveillance in the domestic birds...

Highly pathogenic avian influenza (HPAI) H5N1 viruses continue to pose a significant threat to animal and human health worldwide. Since the onset of the HPAI H5N1 outbreak in South America, our research group has been conducting environmental influenza A virus (IAV) surveillance in different wetlands throughout Chile to detect and characterize circulating IAV strains. Between November 2022 and June 2023, we collected and screened 3275 environmental samples for IAV by RT-qPCR targeting the M...

The 2022–2023 highly pathogenic avian influenza (HPAI) H5N1 outbreak in the United States (U.S.) is the most geographically extensive and costly animal health event in U.S. history. In 2022 alone, over 57 million commercial and backyard poultry in 47 U.S. states were affected. Over 75% of the affected poultry were part of the commercial table egg production sector. Methods: We conducted a case–control study to identify potential risk factors for the introduction of the HPAI virus...

The 2022–2023 highly pathogenic avian influenza (HPAI) H5N1 outbreak in the United States (U.S.) is the largest and most costly animal health event in U.S. history. Approximately 70% of commercial farms affected during this outbreak have been turkey farms. We conducted a case-control study to identify potential risk factors for the introduction of the HPAI virus into commercial meat turkey operations. Data were collected from 66 case farms and 59 control farms in 12 states. Univariate...

In Chile, from December 5, 2022, to date (August 30), 892 HPAI H5N1 HPAI-positive samples have been detected in wild birds, affecting 50 species, with 94 zones under control. To date, more than 35,000 wild birds are dead. In addition, 175 positive backyard bird premises have been detected, with more the 14,000 birds culling distributed in the 16 regions of the country in 97 zones under sanitary control. This is the event 4,775 registered in the WAHIS system. In addition, since March 13,...

Highly Pathogenic Avian Influenza (HPAI), particularly caused by the influenza virus A genus, is a paramount concern for global poultry health. The strains associated with HPAI are known to precipitate mortality rates exceeding 90%. Beyond the immediate and catastrophic impact on poultry, the emergence of HPAI strains disrupts international poultry trade, leading countries to impose trade bans and shake consumer confidence. By September 19th, 2023, Brazil had reported 106 confirmed outbreaks...

Biosecurity may be defined as protection from pathogens or disease. This may include the separation of the flock from living vectors or inanimate objects called fomites. While prevention of host-specific and zoonotic diseases is important, the commercial poultry industry is already preoccupied with the challenges of day-to-day operations. The purpose of this project was to illustrate how surfaces that may seem clean are heavily contaminated with microorganisms that may be responsible for...

Avian influenza was an exotic disease in Mexico until 1993 when the first H5N2 low-pathogenic avian influenza (LPAI) virus was identified. After many months of accumulating mutations, this low-pathogenic predecessor evolved into a highly pathogenic strain. This inevitably resulted in the authorities reporting the first H5N2 highly pathogenic avian influenza (HPAI) virus in 1994. To contain the HPAI virus, the government implemented a massive vaccination program, active surveillance,...

1. Introduction Non-typhoidal Salmonella (NTS) comprises multiple serovars of Salmonella enterica that can cause self-limiting or invasive enteric disease and are transmitted to humans mainly through contaminated food [1,2]. The consumption of poultry products represents a common route of NTS transmission to humans [3], and the increasing prevalence of antimicrobial resistance (AMR) among NTS isolates has become a serious concern [4,5]. Most gastrointestinal infections...
