“Everyone associated with the farm should be vaccinated [against influenza] whether they work directly with pigs or not,” said Heather Fowler, DVM, director of producer and public health for the Pork Checkoff. “That is the best thing producers can do to protect their families, co-workers and pigs from the flu.”

In fact, a seasonal flu vaccination is a public health recommendation and part of the One Health approach to protect people, pigs and the global environment. The Centers for Disease Control and Prevention (CDC) recommends that everyone 6 months of age or older be vaccinated annually against seasonal influenza. The seasonal influenza vaccine is available now, so people should be vaccinated as soon as possible to prompt their immune system to prepare for flu season, which typically stretches from October to May.

“Equally important, farms need to have sick-leave policies in place that encourage workers to stay home if they are suffering from flu-like like respiratory symptoms,” Fowler said. “While it’s especially important to stay off the farm, people need to stay away from public places and take time to rest and recover. This will help shorten the duration and impact of the infection.”

Influenza is a virus, and infections can last three to seven days, although a cough can persist for more than two weeks.

“People with active infections can be contagious for several days,” Fowler said. “They should not return to work for at least 24 hours after their fever breaks without using a fever-reducing medication.”

Other on-farm practices should receive extra attention this time of year, including reviewing the Pork Quality Assuance® Plus (PQA Plus®) section that addresses influenza. Here are a few critical steps:

1. Animal caretakers should wash their hands and arms frequently with soap and water. Keep hands away from mouth, nose and eyes.
2. Monitor animal health daily and contact the herd veterinarian immediately if influenza is suspected. A rapid response is helpful when treating sick pigs and may also minimise losses and further spread.
3. Maintain proper building ventilation and barn hygiene to help reduce influenza virus transmission.
4. Ensure bird and rodent control programmes are well established.
5. Do not allow anyone with flu-like symptoms to enter the facility, and ask visitors about recent contact with others who may have been ill.
6. Restrict eating in animal areas.

“The good news is that seasonal flu vaccinations are widely available today, including convenient options, such as a quick stop at the local pharmacy or clinic,” Fowler said. “Influenza can be addressed effectively through vaccinations, which help reduce the duration, intensity and spread of the virus. Producers are committed to protecting swine health and welfare, as well as public health. Getting vaccinations and following protocols to reduce the potential transmission of influenza this season is one more step in doing what’s right for people, pigs and the planet.”
