She quoted Uruguayan writer Eduardo Galeano by saying that “sovereignty begins at the mouth,” which underscores the point that decisions about food production and consumption have their weight and consequences.

These outbreaks, along with China’s global leadership as a pork producer, caught the attention of three researchers who started looking into the matter: Larissa Mies Bombardi, a geography professor at the University of São Paulo (USP), German pharmacist Immo Fiebrig, and Pablo Nepomuceno, a technician at USP’s Laboratory of Remote Sensing and Geoprocessing.

For biologist Rob Wallace, the intensive animal farming practiced over the past 40 years is the cause of the new viruses that threaten the planet with epidemics and pandemics.
I would not expect the pig endogenous retroviruses to present such a problem, because they grow to only low titres in human cells and so are unlikely to be pathogenic. the transgene (the gene transferred) is passed on thru the germline. have different genes. somewhere in that engine without removing the original one?
Although there has been limited success in transplanting pig islet and neural cells, a major barrier to the ‘discordant’ xenotransplantation of whole organs from pigs into primates is a phenomenon known as hyperacute rejection.

It follows that modifications to make porcine xenografts resistant to hyperacute rejection may also make any enveloped viruses of pigs similarly resistant to lysis. Animal morbilliviruses (measles-related viruses such as canine distemper virus and rinderpest virus), too, might become pre-adapted for human transmission in CD46-transgenic pigs. According to estimates by the Brazilian Association of Soy Producers (Aprosoja), Brazil exported 60 million tonnes to China in 2019 and may export up to 66 million this year. Stoiber, H.et al. If pigs were to harbour picornaviruses that use the porcine equivalent of CD55, such viruses might readily adapt to recognize human CD55 in transgenic pigs that express both the native porcine and the human forms of the receptor.

In two papers, they show the spatial correlation between increasing numbers of COVID-19 infections and intensive pig farming in Brazil, the U.S. and Germany.
Unraveling the swine genome: implications for human health. Banner image by CNA Brasil/Wenderson Araujo/Trilux. Scand. Nucleic Acids Res. The translation of novel discoveries from basic research to clinical application is a long, often inefficient, and thus costly process. In February 2020, Bombardi, who is also one of the authors of the atlas Geografia do Uso de Agrotóxicos no Brasil e Conexões com a União Europeia (Geography of the Use of Pesticides in Brazil and Its Connections with the European Union), gave the lecture “Living under poison” on the Fru.to food platform. and Zimmerman, T.S. According to the study, the virus poses no imminent threat, but scientists have called for urgent, rigorous monitoring of the virus and human populations, especially pork industry workers. We have sought to generate a new source of rFVIII by targeting expression of the human FVIII cDNA to the mammary gland of transgenic pigs using the regulatory sequences of …
The savings in terms of cost and lost animal lives could be tremendous were genetically resistant pigs to become available to the livestock industry.

“The expansion of soy and corn plantations is clearly correlated to animal feed, both in domestic consumption and in the amount of grains that are meant for exports,” Bombardi says.
