Introduction: Porcine circovirus 2 (PCV-2) is a key pathogen for the swine industry at a global level. Nine genotypes, differing in epidemiology and potentially virulence, emerged over time, with PCV-2a, -2b, and -2d being the most widespread and clinically relevant. Conversely, the distribution of minor genotypes appears geographically and temporally restricted, suggesting lower virulence and different epidemiological drivers.

- - The study focuses on Porcine circovirus 3 (PCV-3), a virus first reported in 2017, noting that its impact on pig health is less severe than that of PCV-2, while highlighting high prevalence rates in wild boars and rural pigs.
- - Researchers analyzed 216 samples from Northern Italy, using qPCR and genomic sequencing, and found that wild boars and rural pigs had a higher infection risk than commercial pigs, with significant viral flow between these populations.
- - The findings indicate that non-commercial pig populations are important for the maintenance and spread of PCV-3, posing potential risks to intensive pig farming.
The immediate refrigeration of meat after slaughter is a key issue for the proper storage and aging of meat. The industry standard cold chain relies on low temperatures and ventilation to lower the internal carcass temperature to 0-4 °C within the first 48 h, i.e.
