A parasite known as the new world screwworm has resurfaced in Texas and New Mexico, with concerns it could migrate to Minnesota.
The screwworm is a fly whose larvae feed on living tissue of warm-blooded animals, says Brian Hoefs Executive Director for the Minnesota Board of Animal Health.
"This maggot feeds on live tissue, which means it literally eats the infested animal from the inside out," Hoefs says of the grisly-sounding parasite.
Despite those concerns, the likelihood it spreads to Minnesota is minimal.
"The most likely route of transmission to Minnesota would be through companion animals vacationing in foreign countries, that are prone to having this parasite," Hoefs explains. "And even moving animals back and forth from our southern states now."
The one thing Minnesota has going for it?
"We can hang our hats on our winter weather. Our cold climate, we'll end that life cycle at some point and kind of stomp it out up here," Hoefs explains. "I honestly think the most likely route of transmission to Minnesota would be through companion animals."
Hoefs encourages producers or farmers to be vigilant about any open wounds their animals. He says you may have and to contact your veterinarian if you notice anything unusual.
