Swine biosecurity
Biosecurity of pigs at the farm level is the set of practical measures taken to prevent entrance of infection into a pig farm and control the spread of infection within that farm. The goal of a biosecurity program is to keep out pathogens that the herd has not been exposed to and to minimize the impact of endemic pathogens. Pig farm security can be defined as the planning and implementation of a program to minimize various types of risk that can have detrimental effects on the farmstead and pigs. Biosecurity and security procedures are intertwined to enhance the health and productivity of pigs. Numerous factors are involved in the development and maintenance of a cost-effective program for biosecurity. These factors can be thought of as links in a chain; a biosecurity program is only as strong as its weakest link.
ll farm biosecurity and security risk factors are unique to that farm and, thus, each biosecurity plan should be farm specific. The best plans are created by working with a swine veterinarian or veterinary consultant who has extensive knowledge of the farm, employees, and local risk factors.
The application of biosecurity measures differs among farms due to the geographic location of the farm, proximity to other pig farms, epidemiological situation (causes, distribution, and control of disease in the herd), type of swine operation, level of technology used for production, and whether other people are employed on the farm.
Introduction As African swine fever virus (ASFV) continues to spread across Southeast Asia, classical swine fever virus (CSFV) expands within Japan, and foot and mouth disease virus (FMDV) reports continue from China, there is increased concern that foreign animal disease (FAD) may enter previously naïve areas. Their continued entry would be devastating to the global swine industry, but also to those that produce feed and ingredients fed to pigs. In...

1.1 | Introduction
Effective biosecurity protocols are essential towards protecting the health status of swine farms. In the United States, tremendous resources have been invested to reduce the risk of viral pathogens, such as the entry of porcine reproductive and respiratory syndrome virus into susceptible populations. Protocols including shower in-shower out, transport...

During 2019, outbreaks of S. zoo septicemia were reported in Ohio and Tennessee with mortality up to 50%. Then, in January 2021, a sow herd in Indiana experienced abnormally high mortalities related to S. zoo. The emergence of S. zoo associated with mortalities at a level not previously seen in the US prompted the Swine Health Information Center (SHIC) to fund a project conducted at Iowa State University (ISU) and the National Veterinary Services Laboratory to meet the urgent need for...

Introduction Salmonella is a worldwide-distributed pathogen that affects both humans and animals 13 . This microorganism is usually associated with intensive animal production, such as swine, since the confinement of animals facilitates the transmission and persistence of the pathogen in farms. Salmonellosis may cause significant economic losses due to mortality, morbidity, stunted growth, increased feed conversion rates and costs of non-specific...

1. Introduction The first set of cases of African swine fever (ASF) in Latvia were detected in the wild boar population at the eastern border with Belarus in June 2014 [1–3]. The disease continued to spread over most of the territory of Latvia within the following years [4–6]. Similar to other ASF affected countries, the infection cycle is maintained by wild boar and this remains a permanent threat for the domestic pig industry [1,7,8]. In parallel, to the epidemic...

In a recent panel with Farm Journal, three experts shared their insights on African Swine Fever and the lessons learned from the effects of the ongoing COVID-19 pandemic.
Gordon Spronk (President of Pipestone Veterinary Services) mentioned that “ASF continues to spread across the globe. It was a threat when it was found in the world’s largest swine population in China and continues to be a threat now.”
Spronk added: “Our vision is to keep it out of our...

1. Introduction African swine fever (ASF), a fatal disease in domestic pigs and wild boar, has become a serious economic threat to the pig farming sector with global ramifications, more than ever underlined by the recent spread to China, Mongolia and Southeast Asia [1]. It is causing tremendous losses in the industrial pig sector but also affecting livelihood of small-scale pig holders in rural areas. In 1921, the disease was first described in Africa, where the disease...

1. Introduction Astroviruses are emerging viruses in the family Astroviridae, which is divided into two genera: Avastrovirus andMamastrovirus[1]. Astroviruses are non-enveloped, 28–30 nm positive-sense, single stranded RNA viruses [2] that can cause disease and be detected in the feces from a wide variety of mammals and birds [3–9]. Porcine astroviruses (PoAstVs) are genetically diverse and are distributed worldwide [10] with five genetic lineages...

1. Swine Melioidosis Melioidosis, an infection endemic to Southeast Asia, northern Australia, and other tropical areas, is caused by the soil-dwelling Gram-negative bacterium Burkholderia pseudomallei, which is known to contaminate water sources [1]. The infections are cyclic and correlate with rainy seasons, which may be due to environmental disruptions such as flooding. While creating a major health concern for humans, B. pseudomallei is also a threat to various animals...

As a result of COVID-19, veterinarians need to look at biosecurity in new ways. As practitioners we have to focus on protecting pigs and maintaining the economic viability of the farm. We are trained to deal with zoonotic diseases with a primary goal of protecting ourselves, our clients, and the food supply chain. Yet, now we are being asked to think more broadly, more holistically as an occupational (One Health) specialist, thinking about the health of farm employees, their families, and...
