Good biosecurity can help to achieve the top parameters in areas of production. Good HACCP procedures should be developed and followed so that production can be sustained. Some good rules of biosecurity to follow include batch rear, all-in-all-out, thorough washing, degreasing detergent, disinfection, fumigation, water system sanitization, and investigation of other disease vectors (such as rodents or insects). Detergent is extremely useful combined with hot water while washing. Check approved dilution rates to obtain the best deal for the rooms on your farm. Proper equipment should be worn when fumigating so that it does not affect the respiratory system. It is not worth it to always buy the cheaper disinfectants because of the new and emerging diseases that they might not protect against. Water lines contain some potentially hazardous bacteria and should therefore be adequately sanitized. Modern biosecurity practices are not as costly as they may seem, plus they increase returns greatly. Biosecurity of pig transport is a major and possibly the most important concern. Biosecurity audits would be able to help maintain an acceptable level of practice.
