How To Eliminate Porcine Reproductive and Respiratory Syndrome Information PRRS With Hydroxyls
Definition and Occurrence of Porcine Reproductive and Respiratory Syndrome
PRRSV is a viral disease that causes reproductive failure in animals and respiratory disease that occurs in pigs. This is a very significant disease that has disastrous economic effects on the U.S. swine production, which is why so many people are worried about how to eliminate PRRSV.
This virus can occur in pigs of all ages. While it is more obvious when sows are affected by reproductive failure or impairment, it can also happen to boars as well. Respiratory syndrome is most often seen in younger pigs but can occur in breeding stock and finishing pigs.
While only in a few countries in the 1980s, PRRS is now a worldwide problem. In the U.S., it is both endemic and epidemic.
The History of PRRS Outbreaks
The first outbreak in the US was in 1987-88 but a few years later, it had been reported in Europe, Canada, and other countries. This disease was first called a syndrome and was often confused with other diseases. While there has been a lot of research completed on the PRRS virus in the past two decades, there is still a lot of confusion regarding controlling the disease. This disease affects producers and entire systems have been designed to help eliminate or control the spread of the PRRS virus.
Etiology and Epidemiology of PRRS
This virus is an RNA virus. The U.S. virus is distinct from the European isolate while they are still related. While the virus can be easily inactivated with disinfectant, phenol, and formaldehyde, it is only a little resistant to regular environmental degradation.
This virus is able to persist for a very long time in carrier pigs. More than 200 days is not uncommon but most pigs will become immune around two months and stop shedding the virus. Shedding is the most common form of infection in a population as the virus is very infectious. It is present in semen, urine, feces, and mammary secretions.
Sows can deliver piglets that are already infected and boars can infect dams while breeding. This makes it very important for researchers to learn more about how to stop PRRS virus transmission.
Once transmission of the virus has occurred, it will infect the body and cause pneumonia while making the lungs more susceptible to other pathogens. It can cross the placenta in late gestation and can kill a fetus. Abortions are common and recovered sows can be re-infected.
Clinical Signs and Lesions PRRS
Not all pigs infected with PRRS display clinical signs. The signs will vary depending on the age of the pig, other diseases, herd size, the age of the infection, and the virulence of the PRRS virus. Boars, sows, and gilts all can experience anorexia, vomiting, lethargy, fever, and depression. Reproductive problems are a common sign and piglet mortality is high.
Younger and finishing pigs will experience depression, fever, lethargy, stunted growth, and depression. Some common first symptoms to watch for are lethargy, sneezing, and fever. Post-weaning mortality is common, especially when the strain is highly virulent and when it causes additional infections.
An infection results in lesions in the lymph nodes and lungs. The lymph nodes will be swollen and cystic.
Porcine Syndrome is very dangerous and can quickly kill a group of pigs. It’s best to detect this virus during the early stages. Aborted piglets can be tested to rule out infections and fresh tissue can also be used to detect PRRS.
There’s no one way to control PRRS because the virus varies so much and is transmitted so easily. Smaller herds can be controlled while larger ones are much more difficult to manage. The goal is often to stabilize the infection by creating immunity in the breeding animals. This will prevent reproductive failure and makes it less likely for piglets to be born with the virus.
Boars need to be quarantined when introduced to a herd and offspring and sows need to be treated or removed from the herd. Some vaccines are available but they are not consistently effective. Cleaning the facilities can be useful as well.
Kill the PRRS Virus with Hydroxyls
It is very difficult to kill PRRS virus , which is why other treatment options are important. Using an Odorox/Pyure Hydroxyl Generator air machine in the space can help to eliminate bacteria, odor, and viruses in the air and on surfaces. This is a great way to control the spread of PRRS and keep your herd healthy.
This past holiday season, I experienced significant smoke damage in my home from an electrical malfunction in my oven, which occurred when running the oven cleaning cycle on a timer in the middle of the nightÑit appeared that the thermostat had stopped working, and the oven temperature just kept rising and rising. When the smoke detectors went off, I wakened and opened my bedroom door on the second floor and saw nothing but smoke in the hallwayÑI could not even see downstairs. There were no flames, just heavy smoke.
The smoke had traveled throughout the first and second floor of my home. A strong odor was detected in the air, and it went into all the closets on both floors, affecting most of the clothing in them. I opened the windows in the home to get cross ventilation and waited outside until sufficient smoke at exited so I could go back into my home. At that point, what remained was a foul odor from the smoke, which was from the protein in the oven as well as some of the plastic surrounding the oven.
The next day, when I went to a meeting, several people in the meeting noticed the smoke odor on my clothing and asked if I had been in a fire. This was an uncomfortable situation to say the least, as I was expecting to host family during the holiday season, not to mention the embarrassment experienced in client meetings. Anxious to remedy the odor problem I contacted Odorox Air Technologies (OAT) in Basking Ridge NJ to see if their Odorox equipment might be able to help my situation.
The guys contacted a local Paul Davis restoration firm, who agreed to operate the Odorox hydroxyl generators at my home to assist in the clean up. Felipe Rodriguez ("Phil") from Paul Davis Restoration & Remodeling followed the instructions given to him by Odorox personnel, and in a matter of just a few days successfully removed the smoke odor from my house (most of it had dissipated after just one day). Paul Davis had installed three of the Odorox machines on the two floors as well as a number of fans to move the air through the house.
Besides the obvious benefit of eliminating the smoke smell, I appreciated not having to leave my home during the clean up processÑthat is because the clean-up process does not use any ozone, which would not have been safe to be around..
It also was interesting to note that the local Maryland Paul Davis folks, having not heard of this hydroxyl technology, were very skeptical of its ability to work. When they came and installed the equipment (shipped to them by Emerald), they said that they could come back the next day with their own equipment to take out the smoke that the Odorox equipment didn't do. When they came back the next day, they were truly amazed at how quickly most of the odors had already been removed much faster than through their more traditional methods they became believers literally overnight. And given that this technology did not require that I vacate my home and dry clean my clothing, treat carpet, etc., they were more than impressed.
Unrelated to the smoke damage, Phil found some mold in my basement (it was from a water leak a few months earlier). I had mentioned that the Odorox equipment could kill the mold spores as well. So once the smoke cleanup was done, and following consultation with the Odorox personnel, I moved one of the Odorox units on the job to my basement to deal with the mold. I am pleased to report the mold is gone with the help of the Odorox and additional clean-up from the restoration crew.
As a business owner and building professional who works with commercial and institutional facilities managers facing odor, mold and other indoor air quality issues threatening their companies, I can say with a great deal of confidence that the Odorox hydroxyl technology will eliminate these types of problems faster and with less disruption and at a lower cost than other previously available means. A big thanks to Odorox!

After researching many air purification solutions on the market today, we chose the Odorox hydroxyl processors for the myriad of areas where we host our students. Many of our special services were open and operational during the first few weeks of the pandemic. The Odorox Pyure hydroxyls provided a sense of comfort for our staff and parents while mitigating the risk of exposure and spread of the virus.
We have been regularly using it in addition to our enhanced disinfection protocols as we are determined to provide a safe, secure, clean, and healthy environment as best we can during a pandemic.
Our administration and maintenance staff are thrilled with the performance and are looking for even more ways to utilize the technology.
