 Did you eat pork today? Over 60% of the world's pig population is in Asia. And pork is widely consumed. But you know what? This delicacy, which is a source of food and income for millions of people, is at risk. In recent years, African swine fever, a deadly pig disease, has been spreading through Asia and the Pacific. It has killed millions of pigs, bankrupted farmers, devastated livelihoods of the small holder village farms, and had a huge impact on pork production all over the world. The ASF virus is very tough and the fatality rate can reach 100%. You can survive in pork products, contaminate as well on the surface of production equipment, including or other materials. If you don't pay attention and follow good biosecurity practices, the virus could get into your farm anytime. There is also another danger. There are some unlicensed products on the market sold as ASF vaccines, but they're either fake and don't protect pigs at all, or have been developed without undergoing thorough testing and are not safe. Vaccines are important tools to combat contagious diseases in humans and animals, but they need to be properly tested for safety and efficacy before they are approved for use. The ASF virus is particularly difficult to make a safe and effective vaccine for and right now, no country has authorized any ASF vaccine. You won't know what is in a vaccine that is not nationally licensed and may introduce new and different strains of ASF virus. If you're not sure about what is safe to use, contact your animal health authorities for trusted information. In fact, ASF can be prevented by strictly following some key biosecurity procedures, which are currently the best recommendation to keep your pigs healthy and protect them from ASF virus. You should strictly control access of staff and visitors to the farm, prevent wild boars or other animals from contacting your pigs, maintain disinfection and segregation between different parts of the farm at all times. Teach all staff so they know how to do this correctly. Always wash your hands and take a bath thoroughly before and after visiting another farm. Wear dedicated clothing and footwear on the farm. Clean, scrub and disinfect vehicles, footwear and equipment. Ensure you remove all visible organic material before disinfecting. Do not feature pigs with swell or kitchen wastes unless they're properly boiled for at least 30 minutes to kill ASF virus. Segregate new pigs for 30 days. Completely isolate any animal that looks sick and contact your local veterinary services immediately. Create and maintain physical barriers to limit the opportunities of diseases spread by humans, animals and equipment. If you always follow these procedures, you can keep your pigs safe and healthy. And remember, no matter how tempting it may be, never use any unlicensed vaccines. Prevention, control and safety measures must be a constant part of your daily work.
