Chinese Pigs

 
 
I. 
 
The pig has historical, cultural and even astrological significance in China. 
 
And whilst the pig hasn't always had the best of reputations amongst Westerners, the Chinese have traditionally associated this intelligent and sociable animal with positive things, such as wealth and happiness. 
 
And good eating: for whilst the Chinese consume pretty much anything under the sun, it's pork that has long been the main source of protein in their diet. 
 
In a country of 1.4 bilion people, that means a lot of pigs have to be reared each year; which means in turn that industrial farming has to be elevated to a whole new level - in fact, to multiple new levels ...  
 
 
II.
 
The world's biggest single-building pig farm has just opened in Hubei province, central China; a 26-story Tötungszentren, with a capacity to slaughter 1.2 million pigs each year. This is the Communist Party's solution to the people's insatiable demand for pork. 
 
The first few thousand unlucky sows were admitted to the farm - if we can still use this term - at the beginning of last month. When fully operational - and when a second building of equal size is finished - this pigsty in the sky will house around 650,000 animals, who will be monitored from a central control room and fed via 30,000 automatic feeding spots, operated at the click of a button. 
 
Temperature and ventilation will be controlled by an artificially-intelligent computer system. Waste material will be treated on site and used to generate energy in the form of biogas. Workers will be required to be screened for disease and subject to multiple rounds of disinfection before they can enter or leave the farm; not that they can leave apart from when taking a weekly break.
 
Supporters say this high-rise production model is cost efficient, biosecure, and environmentally-friendly, compared to traditional farming methods. They tend not to comment on the welfare of the poor pigs in such stressful and unnatural conditions. 
 
Critics, on the other hand, argue that large-scale intensive farms ultimately increase the likelihood of serious disease outbreaks - as well as increase the potential for infectious pathogen mutation, which just might cause us to get sick and die:
 
"China is not the only country facing challenges from emerging zoonotic diseases, but it has become clear that the country faces bureaucratic, societal and ecological factors that magnify them into global threats" [1].
 
Which is a sober note to end on - though one that might make any pigs dreaming of a way to extract a symbolic revenge upon a human order that treats them with such cruelty and contempt, squeal with delight [2].

Zoonosis (Revenge of the Animals)



Recent reports of the rare viral disease known as monkeypox recorded in the UK for the first time - first in Cornwall, then in Blackpool - oblige one to reconsider the question of zoonosis ...    

The term, zoonosis - from the Greek ζῷον (animal) and νόσος (sickness) - refers to the fact that some infectious diseases can naturally be transmitted between animals and humans. Examples include potentially deadly conditions such as Ebola, rabies, and salmonellosis, as well as the relatively mild - but still deeply unpleasant - monkeypox.

Many strains of swine and bird flu are zoonoses and HIV was originally a zoonotic disease transmitted to people in the early part of the 20th century from our simian friends, though it has since evolved to a separate human-only condition.

Despite the urban myth that infection with HIV was due to human-ape sexual contact, it was most likely due to the consumption of the latter served as bushmeat. Indeed, eating infected food is one of the most common modes of zoonotic transmission.

However, as zoonoses can be caused by a range of pathogens - viruses, bacteria, fungi and parasites - there are numerous modes of transmission, both direct and indirect. Sometimes, this can involve a third party or intermediate species, known as a vector, which carries the disease without itself being infected; think mosquitoes and malaria. 

The fact is, like it or not, zoonotic transmission can occur in any context in which there is intimate contact with animals. Be they livestock, domestics pets, or wild creatures, they'll always find a way to undermine the health of man and extract a symbolic revenge upon a human order that treats them with disdain.
