It looks like each county adjacent to 2 hot counties is quarantined. Look at Val Verde for an example. Just at a glance that's what I would take away from the map.

ETA. That's not it. Sorry - I see other counties that doesn't hold true for

TSCRA webinar updates today online. 1-2pm. Tscra.org
Will try to watch on my cell phone

TLDR the best takeaway I heard was giving All newborn calves an injection asap after birth if in the NWS quarantine area.

Maybe it has to do with where the confirmed case is in the county.

If you look at where the worm has been found it is kinda in the areas where the Texas POE's that were authorized to import cattle were/are. Del Rio, Laredo, Eagle Pass, and Presidio were the only POE's that could do live cattle in Texas and I don't think Laredo did all that much, from what I understand/past recollection it was mainly Eagle Pass and Presidio that did more cattle. New Mexico crosses quite a bit more than TX does, or at least it did at one time.

Infested zone is a 20 km (12.5 mile) radius from location of confirmed case. There are quarantine/movement controls in place by TAHC for any properties in an infested zone. Surveillance zone is a 20 km area around the infested zone where enhanced monitoring takes place. Sterile fly dispersal occurs in both infested and surveillance zones.

That is why some cases end up with multiple counties labeled as infested and some do not.

So when that circumference enters another county, that entire new county is quarantined?

I don't believe so. Here is the map from TAHC.

https://www.tahc.texas.gov/emergency/nws.html

It shows the actual infested and surveillance zones, not just an outline of the counties where NWS has been confirmed.

It has nothing to with the county…quarantine zones are based off of the radius from the infected animal/property.

Well that's what I was thinking, but it's showing Webb entire county and there's not been any hound in Webb. Webb is about 2 million acre county so fairly big. Using the circumferences cited why is the entire county quarantined?north line of Webb is about 60 miles from south line.
What am I missing?
Webb also enjoys about 60 miles of lovely riverfront acreage along Rio Grande. My tick riders are saying that Zapata county is about as safe a place as can be due to tick program and fly bombings. So why is Webb along river not safe and not in quarantine as well?

I think the maps that show the entire county highlighted are simply showing that there is a positive case in that county.

Well Webb has not reported one but the counties adjacent have. But yes, as I understand a portion of Webb should fall within the outer ring of several cases.

I saw a copy of the Premise Spray concoction the King Ranch is using and figured I'd mix some and treat around the pens/barn. Permethrin, of course, clove oil, peppermint oil, marker dye, & water.

I may or may not have any flies around for a while…. But I can guarantee that MrsCP is going to have some questions when I get home tonight. I can't tell if I smell like I've been in a doctors office or a titty bar, but it was definitely one of the two.

If it was a Vanilla smell, she would know for sure. Lol.

I've used Lintox Hd for years- a quart to 25 gallons of water mixed and sprayed on cattle in the chute. It works great and last a month or more but also stinks. My wife has me leave those clothes at the ranch house and wash myself at the washateria. She swears it makes our home machine stink a long time.

Sadly, knowing Medina County extremely well, I'm actually surprised it hadn't shown up sooner (but definitely glad it hadn't - well at least discovered). I've got too many good friend there and wish them well (same as all others affected)

On the preacher pulpit, talked to several small family ranchers today (40-100 head) about what to expect if it moves up into our area. All could not understand even the simplest concepts of prevention vs treatment, what are "sterile flies" - ugh. They all simply said "you got ivermectin, don't you"

I think that may be something that confuses folks. They think it's some type of intestinal worm rather than a maggot.

Maybe that confusion is because the FDA very publicly authorized emergency over-the-counter use of ivermectin injectable specifically stating for prevention of new worm screwworm infestations.

https://www.fda.gov/animal-veterinary/cvm-updates/fda-issues-emergency-use-authorization-over-counter-injectable-drug-prevent-new-world-screwworm

We are only monitoring ours. They get regular ivermectin treatment and fly sprays weekly, at least the ones that we can. I have a lot that will disappear over the ranch and weeds the minute they hear my truck because they know I'm feeding and spraying. We won't do more until it's necessary. So far all is well in our section of Medina county. Time will tell.

Not these guys. We've got lots of educated gentlemen ranchers who are smart and research, read, and educate themselves. These few were mountain ranchers that don't know what the FDA is and likely maybe finished sophomore in HS.

Well, that may very well be true. But the fact remains that their opinion and the FDA's is in alignment. The post made it seem like they were idiots but I'm just saying that their opinion isn't wrong and they aren't idiots at all according to the FDA since their positions are in alignment.

If ivermectin is not suitable, then they need to reverse that position and make that known so that even the high school graduate ranchers can also be part of the fight. That's all I was trying to say.

I said they didn't understand prevention vs treatment. And they felt that ivermcetin was automatically both as they think prevention and treatment are synonymous. I don't know why you want to argue this when it's not germane to my point of how many people raising cattle won't have the comprehensive capability to be able to follow protocols in an outbreak.

Although I did not state it specifically, I guess my overall point I was trying to say was that the only thing that will be universal in stopping this is the sterile fly program. Take it out of the hands of all the small individuals.

Didn't think it was an argument. More trying to understand your point. I guess what worries me more than small operations not understanding prevention vs treatment while using products that are described as handling both are those like my smaller neighbors on a few hundred acres that have a pile of animals and show up to the property once every 6 weeks to toss out hay and feed and aren't there long enough to have inspected anything. They don't prevent OR treat.

I agree the sterile fly program is about all that's really going to nip it on the large scale.

Ive been on two TSCRA webinars this week. The understanding that I get is that Ivermectin will prevent but not treat while Dectomax does both.

Anyone with livestock should have a basic comprehension of treatment vs. prevention and know that ivermectin is not a cure all for everything. Sadly, ignorance abounds.

Got called by TPWD today. Quarantine zone in Medina Co and Surveillance where I am in Bandera. State lining up landowners willing to host traps, sterile larvae boxes, and allowing access for surveillance.

Not gonna lie. The neighbor states have incompetence galore and have essentially no state programs or even attempts at it - left up to individuals/local agencies which is why I'm trying everything to be as up and prepared but this is an issue of the size that unfortunately we need the government programs to be effective. It's up to y'all in Texas to be the front line and final line. God's speed!
