The final, formatted version of the article will be published soon.

Live pig specimen collection can be time-consuming as it may require physical restraining. Non-invasive methods for live animals that don't involve blood spillage are available but some may present limitations of application or pathogen detection. Alternative methods focused on the mortality are also available but may derive in blood spillage. As biocontainment and bioexclusion are of concern, especially for pathogens such as the ones that cause classical swine fever and African swine fever, alternative methods can be applied. This article presents the results and opinions of the use cardiac puncture as an alternative of specimen collection from dead pigs. This method was used in two separate studies involving porcine reproductive and respiratory virus detection from blood of dead pigs of different ages. Blood was successfully obtained from 286 suckling and growing pigs, that were euthanized or died during outbreaks of the tested virus. While only 273 samples could be tested due to the other 13 not yielding enough sera of having inhibitors, of those 95% had positive detections for the virus. This method was not only feasible for obtaining blood and test the sera, but also avoided environmental contamination with blood, offering an alternative tool for collection during outbreak investigations.
