As the number of confirmed New World screwworm cases in the U.S. grows to four<\/a>, Texas and the federal government are working to stop the threat before it spreads.
Texas Gov. Greg Abbott<\/a> escalated the state response Friday by issuing county-specific disaster declarations for Zavala and Uvalde counties as he warned residents to brace for a \u201cchallenging summer” during a\u00a0June<\/a>5<\/a>news conference<\/a>.
Agencies like the U.S. Department of Agriculture and the Texas Animal Health Commission have also moved into a coordinated containment effort to avoid potentially billions in losses for ranchers and the broader food supply.
Here is what we know about the two confirmed cases, the quarantine zone and how state and federal officials are responding.
The U.S. Department of Agriculture confirmed the following in three in South Texas, two in Zavala County and another in La Salle County. The fourth case was reported in Gillespie County \u2014 near Fredericksburg, Texas.
A case was originally in Andrews County; however, USDA later reclassified<\/a> the case to New Mexico \u2014 marking the first case in the state.
Texas Gov. Greg Abbott further escalated the state’s response on Friday, June 5, by issuing\u00a0a disaster declaration\u00a0<\/a>for Zavala and Uvalde counties.
According to the order, the governor has reallocated all available state resources that “are reasonably necessary to cope with this disaster, and temporarily reassign any such resources that could be allocated to address the spread of NWS to the Texas New World Screwworm Response Team,” prioritizing the resources to Zavala and Uvalde counties first.
Abbott also directed the Texas Division of Emergency Management to activate the Texas State Emergency Operations Center at a Level II \u2014 escalated response \u2014\u00a0on Monday, June 8.
\u201cThe protection of our ranchers, livestock producers, deer breeders, and the Texas economy from this pest is a top priority. We have eradicated this pest before, and we will do it again in close cooperation with our federal partners. Texans should stay alert, check animals daily for wounds, and report any suspected cases immediately,\u201d Abbott said in a statement.
Abbott had already issued a statewide disaster proclamation<\/a> in response to the NWS threat on Jan. 29 and has renewed it monthly since then.
The\u00a0Texas Animal Health Commission<\/a>\u00a0(TAHC) updated its emergency order<\/a> on Friday, June 5, expanding the quarantine zones covering parts of Zavala and Uvalde counties southwest of San Antonio<\/span>. The original order,<\/a> signed by Executive Director Lewis Dinges on June 3, imposed restrictions on the movement of animals out of the area after a Zavala County calf tested positive for NWS.
Under the order<\/a>, the quarantined area is subject to the following:
The order went into effect immediately on June 3 and is set to remain in effect until the quarantine is lifted by TAHC.
According to the USDA<\/a>, the department is continuing its sterile fly release operations over the infested areas and along the U.S.-Mexico border.
Starting on Tuesday, June 9, aerial dispersal flights originating from the sterile fly dispersal facility at Moore Air Base in Edinburg, Texas, will begin.
Due to the nature of the releases, USDA said it is possible that sterile NWS flies could be caught and reported, but it has taken steps to ensure officials can differentiate between sterile and wild NWS flies.
According to the USDA<\/a>, the New World screwworm (NWS) is a parasitic fly that impacts livestock, pets, wildlife, and, less commonly, people and birds. The fly’s larvae feed on the living tissue of warm-blooded animals.
USDA reports that the current risk to animals and people in the United States remains\u202fvery low and that NWS is not contagious.
Rather, screwworm infestations begin when a female fly lays eggs on a wound or body opening. The eggs hatch intolarvae that burrow into the wound and feed on living tissue, then after about 7 days of feeding, larvae drop to theground, burrow into the soil, and pupate.
The adult screwworm fly emerges from the soil after 7 to 54 days.
According to the TAHC<\/a>, the commission was established in 1893 and is charged with protecting the state’s domestic animals “from all contagious or infectious diseases of a malignant character.”
The 13-governor-appointed commission has legislative authority to make and enforce regulations to prevent, control, and eradicate specific infectious animal diseases that endanger livestock, representing the general public and various livestock industries and professions.
Under\u00a0Title 4 of the Texas Administrative Code<\/a>, the commission has the authority to quarantine any area, county, or part of a county within the state that has been determined to be infested with NWS, as laid out in Section 37.1.<\/span>
