Two lingering cases of porcine epidemic diarrhea (PED) at different finishing units were frustrating Ross Kiehne, veterinarian with Swine Vet Center, St. Peter, Minnesota.
“These barns tested positive to PED before, but these were sites we wanted to use for gilts,” Kiehne explained. “We cleaned up the barns and utilized normal disinfectants. We put gilts back in there, but oral-fluid testing indicated the pigs were positive for PED.
“We didn’t see any clinical signs so we thought it might be an environmental contaminant. But we weren’t going to use the gilts as long as they were testing positive, even if we thought it was a false positive.”
Fogging allowed over pigs
A possible solution was a disinfectant that could safely be fogged into barns with pigs present. Kiehne had heard about preliminary university tests indicating a disinfectant called Zoono Microbe Shield was effective for many diseases on impact plus residual action for at least 7 days.
“It’s a fairly new disinfectant that you can apply right over the pigs,” he said. “I convinced the owner to spray with Zoono. We sprayed and tested multiple times. The pigs tested negative every time, so we were comfortable using those gilts.”
If the product hadn’t worked, Kiehne’s client may not have been able to use the gilts. Or they needed to go through the process of moving the gilts out, cleaning and disinfecting again to try to achieve negative tests.
“What I like about Zoono is it is very safe and can be sprayed with pigs in the barns,” Kiehne said. “And the 7 days of residual action is very significant. All other disinfectants kill on impact only and offer no other action.”
Since the success with clearing PED from the finishers, Kiehne has fogged the disinfectant in rooms with pigs from 3 to 4 days old up to sows, with no adverse effects.
“We are trying to utilize this product more now for similar circumstances,” Kiehne said. “I think it was an environmental contaminate that was causing us some headaches with the PED tests. Now I’m going to do more testing over pigs for other diseases.”
In addition, more information on Zoono’s use in swine should be available soon from a study conducted by Derald Holtkamp, DVM, at Iowa State University. Holtkamp is evaluating Zoono and should have results later this summer.
Zoono kills ASF, COVID-19
Zoono’s disinfectant product has been thrust into the limelight the past few years after outbreaks of African swine fever (ASF) and COVID-19 in China. The product developed by Zoono Group Limited, a New Zealand company, kills ASF and COVID-19 on contact and offers residual action up to 30 days for some pathogens, according to information on its website.
Key to the product’s success is the Zoono Microbe Shield that forms a bond with surfaces to inhibit growth of microbes. The EPA-approved product is safe for humans and animals because it uses a technology to kill the microbes without dangerous chemicals.
Companies like United Airlines now use Microbe Shield to provide a layer of protection in the passenger cabins on everything from seats and tray tables to lavatories.
