Chicago, – New World Screworm, a destructive parasitic that survives cattle and other wild animals, traveling north from Central America to Mexico and enhances previous biological barriers that maintains inherent pests over decades, said experts.
Washington stopped the import of cattle from Mexico in May, cited in Mexico, about 700 miles from the Texas border. Already on a multi-decade low with a flock of American cattle, the closure can further increase the record-high beef prices by placing more calves than the American cattle supply.
What is New World Screwm?
Screworms are parasitic flies whose women lay eggs in wounds on any warm blood animal. Livestock and wild animals are usually suffering. Once laying eggs, hundreds of screws larvae use their sharp mouth use their sharp mouth, which through feeding living meat, enhances the wound and eventually killing your host when left untreated.
When the screwomes infect a cow, a small scraper, a recent brand or a healing year tag, a gap can quickly become a gap wound, which is carpet with magots, which puts the entire herd at risk of infection. In the 1960s, the screws from the US were erased when researchers began to release a large number of fruitless male screwed flies, intercourse with wild female screws to produce prohibitive eggs.
Why is this for American consumers?
The US usually imports more than one million cattle from Mexico every year. Import suspension would probably contribute to the rising prices of beef to beef cattle, which decreased after forcing herds to herds after the drought.
Experts said the prices of US beef got a boost from a separate import suspension from Mexico, which lasted from November to February, and the pressure on the prices should be made through the summer grilling season. Mexican cattle are usually fed on the American fields for five to six months before slaughter, and a low slaughter rate can increase the prices of beef.
Although the fly is hundreds of miles away from the border, any outbreak in the US will tighten the supply of cattle and put other livestock and domestic pets at risk. Screworms will also feed humans, if they can, Dr. Timothy Goldsmith said, a veterinary drug professor at the University of Minnesota. Goldsmith said that homeless people would be particularly insecure for infection as they sleep out and have less access to hygiene products and medical care.
What is being done to control the outbreak?
A factory designed to breed and sterilize the screwm in Panama is releasing 100 million sterile flies every week, but experts say more factories need to come online quickly to choke the spreading north of the fly.
Sonja Swigar, an entomologist at the University of Texas A&M, said that screws cannot fly more than 12 miles in themselves, but they can cover a big distance by burying inside their hosts. Flies have already been passed from the most narrow parts of the ground in Panama and Mexico, which means that there is a need to release more sterile flies to control outbreaks.
On Tuesday, the US Agriculture Department announced that it would invest $ 21 million to replace a fruit fly factory in Mexico to produce sterile screws. The agency said that the border would reopen for the import of cattle by the end of the year.
How can this American cattle affect Ranchers?
The USDA estimated that a screwborm outfit would give Texas’s economy a cost of $ 1.8 billion in livestock deaths, labor costs and drug expenses. After decades of abolition, most cattle rankers no longer have experience or tools to diagnose and treat screws. The infection can be corrected, but treatment includes removing hundreds of larvae and disinfecting wounds completely, a time-taking, price and labor-intensive process.
Livestock economist David Anderson at the University of Texas A&M said, “This is an insect we don’t want back. It’s a bad thing.” “I can’t imagine dealing with him. It’s gross.”
