Animal health and disease prevention are one of the main concerns for agricultural industries working with livestock. Although governments and international organizations set standards to hinder the pathogens causing a threat to animal welfare, sometimes the regulations for disease prevention are not enough. The recent incident in New Zealand, a country heavily relying on its farming industry, is a great example of large and wasteful disease prevention. The government has decided to kill 150,000 cows to eradicate the hazardous bacteria from the national herd and save the economy. There are 24,000 cows already slaughtered. Some of them are transported and slaughtered in processing plants for meat, while some will be killed and buried in animal waste incinerator. For New Zealand, dairy is the main export good, and the eradication program is estimated to cost 886 million New Zealand dollars (€513 million.) Although rendering animals is a common practice to further convert the animal by-product into useful materials and profit, the livestock rendering is currently not carried out.
