Should the pork industry make a more concerted effort to eradicate some of the major diseases that continue to plague production?

Carlos Pijoan, veterinarian at the University of Minnesota, believes the industry should. He cites four reasons why past attempts have failed.

1. Past eradication efforts have relied on signs and lesions to monitor disease instead of concentrating on pathogen detection.

2. There was a failure to understand the problems of maintaining disease-free herds in infected regions – the so-called "area spread" of disease.

3. Eradication solutions were developed for pathogens that were not fully understood, especially their pathogenesis and epidemiology.

4. Information for eradication measures was applied from small-scale experimental trials to large swine populations. Results were not the same in large pig populations as they were in the smaller groups.
