Achievements and Challenges of Classical Swine Fever Eradication in Brazil
Abstract
:1. Introduction
2. Epidemiological History of Classical Swine Fever in Brazil (1888 to 2001)
3. Implementation of Prevention and Surveillance Actions
- Passive clinical surveillance from notification by owners, Official Veterinary Service or third parties;
- Communication of the increase in mortality rates by qualified veterinarians assisting swine breeding establishments;
- Active and continuous clinical surveillance in swine breeding establishments identified as having the highest risk of reintroducing CSF in the FZ;
- Serological monitoring of intensive pig farming (IPF) by the collection of samples in slaughterhouses, from breeders, which were sent for disposal;
- Seroepidemiological monitoring in non-technified pig herds (NTPig) at regular intervals;
- Semiannual serological monitoring in Certified Swine Breeding Farms (CSBFs);
- Ante and post-mortem inspection in swine slaughterhouses.
3.1. Surveillance in Wild Boar
- Passive surveillance based on reports of the presence of sick or dead animals, generating an epidemiological and clinical investigation with a collection of diagnostic material;
- Active surveillance with an assessment of the biosecurity of farms, mapping the distribution of populations and definition of risk areas, analysis of data from the surveillance system, and collection of serological samples by voluntary management agents;
- Serological surveillance carried out by fauna managers (hunters) who voluntarily adhere to the program. The legalized hunter must collect serological samples from these wild boars following biosafety measures to prevent the disease’s spread. To this end, the OVS, in partnership with Embrapa Swine and Poultry Research Center, has carried out various courses intending to train these partners, in addition to producing several instructive technical materials, such as the “Necropsy Manual for Swine” [28].
4. Expansion and Recognition of Classical Swine Fever Free Areas
4.1. Health Status in the Classical Swine Fever Non-Free Zone
4.1.1. Identification of New Outbreaks of Classical Swine Fever in the Non-Free Zone (2018 to 2019)
4.1.2. Challenges in Controlling Outbreaks of Classical Swine Fever in the Non-Free Zone of Brazil
4.1.3. Health Surveillance System in the Classical Swine Fever-Free Zone
