Expert discusses the challenges and prevention of Classical Swine Fever (CSF) in non- disease-free z...



The Brazilian Ministry of Agriculture (MAPA) started, in May, a pilot project for the roll out of its Strategic Plan for a CSF-free Country in the northeastern state of Alagoas. The pilot project is the coordinated effort between the public and private sectors and represents the first step towards vaccinating against CSF in non-disease-free regions.

To demonstrate the absence of viral transmission, Brazil´s current monitoring system relies on data from the passive surveillance of all pig herds in the country, the systematic and active serological survey of both Certified  Pig Breeders Farms (GRSC), culled boars and sows  at slaughterhouses, and backyard pig herds  located in disease-free zones, as well as the serological survey of wild pigs. Annually, data collected from the Brazilian surveillance system is sent to the World Organization for Animal Health (OIE) to ensure the maintenance of the animal health status of CSF-free zones in Brazil.

Current CSF-free regions are also safeguarded by protection and inspection systems in place at Brazil´s international borders with non-CSF-free countries or areas. According to Guilherme Zaha Takeda, Head of the Swine Health Department of MAPA , Brazil follows very strict rules and norms when importing pigs, swine genetic material, and pig products and byproducts. Takeda believes that respecting the import requirements established in the OIE´s Terrestrial Code for CSF and the Codex Alimentarius is crucial.

Brazil´s Strategic Plan for a CSF-free Country

The Strategic Plan for a CSF -free Country will change the way in which the country has been fighting the disease. The Plan is based on the shared responsibility between the public and private sectors and clearly defined obligations, roles, and responsibilities for executing the Plan.

The successful control and eradication of CSF in non-CSF-free zones requires the strengthening of the capabilities of government-run veterinary services, financial sustainability, and the need for awareness and engagement of all players involved. However, these efforts must be accompanied by the elimination of foci and improvements in biosafety of commercial pig farms, adds Takeda.

The non-disease-free zone currently includes the states of Alagoas, Amapá, Amazonas, (except for disease-free zones), Ceará, Maranhão, Pará, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, and Roraima.

Brazil is a country of continental dimensions and very different regional realities. Takeda explains that significant progress has been made regarding CSF control in regions where pig farming plays an important socioeconomic role. Today, Brazil is the fourth largest producer and exporter of pork  in the world and has been consistently breaking its own record in terms of volume of exports. Brazil is expected to break its own record yet again in 2021.

The successful economic growth of Brazil´s pig industry can be attributed to organizational changes, technological improvements, and greater interaction between the public and private sectors.

The Strategic Plan for a CSF-free Country is based on a structured and well-organized intervention in non-disease-free zones, adds Takeda. In his opinion, the intervention is critical for reducing the risk of reintroducing the CSF virus in disease-free zones, thus preventing liabilities arising from both direct losses and market access restrictions due the loss of Brazil´s credibility to control and eradicate the disease.

Protein from Brazilian pork and the international market

Brazil´s credibility and competitiveness in the international market of pork-derived products are intrinsically associated with the quality and trust conferred by the country´s animal health controls and surveillance systems. Importing countries are requiring stronger and more objective and reliable proof of the animal health status of exporting countries related to the pathogenic agents of their interest.

Worth of note is that the OIE currently recognizes three CSP-free zones in Brazil: the first zone comprises the states of Rio Grande do Sul and Santa Catarina; the second zone includes the states of Acre, Bahia, Distrito Federal, Espírito Santo, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Rio de Janeiro, Rondônia, São Paulo, Sergipe, Tocantins and the municipalities of Guajará, Boca do Acre, the southern  Canutama  and the southwest art of the Lábrea , both located in the state of Amazonas, and the third zone comprises the state of Paraná. These zones have successfully provided robust data on the absence of viral transmission.

World scenario

CSF can be found in Central and South Americas, Europe, Asia, and parts of Africa. North America, Australia, and New Zealand are considered  disease-free zones. According to the OIE data, major CSF outbreaks were registered in the 90s, namely in the Netherlands (1997), Germany (1993-2000), Belgium (1990, 1993, 1994), Italy (1995, 1996, 1997), and Japan (starting in 2019).

Biosecurity will be part of the IPVS2022 agenda

To mark its return to Brazil after 30 years, the host city of the  International Pig Veterinary Society (IPVS) Congress, the world´s most important scientific  event on pig farming will be the city of Rio de Janeiro. The theme of the event, which will be held from June 21st to 24th, 2022 at Riocentro Convention Center is “New perspectives for the swine industry: biosecurity, productivity, and innovation”.

IPVS2022 is supported by major players in the Brazilian pig industry such as the Brazilian Association of Pig Veterinarians (Abraves), Brazilian Association of Animal Protein (ABPA), Brazilian Association of Pig Farmers (ABCS), and Brazilian Association of Swine Genetics Companies (ABEGS).

Partners of IPVS2022 include Hipra, MSD, Boehringer Ingelheim, Zoetis, and Farmabase; Supporters of IPVS2022 include Elanco and Ceva.

Ourofino, Trouw Nutrition, Agroceres PIC, Biofarma, IDEXX, and Pharmacosmos are Platinum Sponsors; Phytobiotics, Magapor, Thermo Fisher, Crystal Spring, and Tonisity are Gold Sponsors; and Microvet, VetScience are Silver Sponsors.

IPVS2022 also relies on the support of the following media outlets: 333 Brasil, 333 International, Academia Suína, Ediciones Pecuarias/Acontecer Porcino, Engormix, Feed&Food, MaizYSoya, O Presente Rural, Pig Progress,, Suinocultura Industrial, and SuiSite.

About IPVS

The International Pig Veterinary Society (IPVS) is an association of experts on pig health and production. Established in 1967, IPVS held its first Congress in Cambridge (UK) in 1969 and its latest in Chongqing (China) in 2018.


According to the IPVS, its goals are to organize international congresses to promote both the exchange of knowledge and technologies relating to pig health and production, as well as the education and training of  veterinarians  in pig farming.
