Antimicrobial resistance in bacteria is concerning in both a human and animal aspect. New antimicrobials are unlikely to be developed, so it is important to slow resistance to maintain the effectiveness of the current ones. Antimicrobial resistance happens when a bacteria acquires or develops a gene for resistance. The, since it has increased survival, the gene is likely to spread to a larger portion of the population. Cross-resistance results in bacteria being resistant to multiple antimicrobials, and then the group can be transferred rather than a single gene. Antimicrobial resistance affects pork producers because it can impact animal health, consumer confidence, and occupational health. Currently, surveillance of resistance and prudent use of antimicrobials is the best way to slow the spread of antimicrobial resistance.
