As the United States enters another flu season, the Pork Checkoff is advising producers, farm personnel and others who have contact with pigs to get the seasonal flu vaccination as soon as possible to help protect human and pig health.
Dr. Lisa Becton, director of swine health for the Pork Checkoff, said, "It's always wise for producers and swine farm workers to reduce the risk of getting sick and bringing the flu to the farm or workplace by getting vaccinated. Also, it fits perfectly into the industry's 'We Care' approach to protecting employees, animals and public health."
In addition to getting vaccinated, Becton recommends taking other steps to reduce the spread of infection among workers and of the pigs with human-influenza viruses. This includes modifying sick-leave policies to encourage workers to stay away from the farm if they are suffering from acute respiratory infections.
"Virus shedding is at its peak when the clinical illness is most severe, but people may remain contagious up to 24 hours after symptoms stop, usually three to seven days," she said.
Good building ventilation and good hygiene also will help reduce transmission of flu viruses.
"To prevent pigs and humans from other species' influenza viruses, producers also should look at bird-proofing their buildings, protecting feed from birds and enforcing biosecurity practices, such as the use of farm-specific clothing and footwear," said Becton.
