Parma Ham?

An almighty row seems to be developing between the prestigious producers of Parma ham and animal welfare activists (https://www.theguardian.com/environment/2018/mar/30/row-erupts-between-italys-parma-ham-makers-and-activists-over-pig-welfare). This has largely grown out of footage, suggesting that the pigs used in the production of this popular food, can be individually housed in cramped cages with no attempt at 'enrichment' (as is generally specified in the UK) and can be roughly treated by their handlers. Pigs are intelligent animals and should be treated as such (they are not simply ham on the hoof).
