"Texas" has been a common factor in news re the second confirmed case of Mad Cow in the US...and a USDA official who did not perform duties in accord with regulation.
No mad cow tests at Texas firm in 2004 May 14, 2004 UPI by STEVE MITCHELL
The U.S. Department of Agriculture did not test any cows for mad cow disease in the past seven months at the same Texas facility where federal testing policies for the deadly disorder were violated last month, United Press International has learned.
The USDA also failed to test a single cow in 2002 at another Texas slaughterhouse that processes high-risk, downer cows, according to agency testing records obtained by UPI under the Freedom of Information Act. Downer cows are unable to stand or walk, which can be an indication of mad cow disease, as well as other disorders.

As UPI previously reported, USDA's mad cow testing records for the past two years show only three tests had been conducted at Lone Star in 2003 and none in 2002.
The low-level of testing irks consumer advocates because Lone Star, the 18th largest slaughterhouse in the country, processes high-risk, older dairy cattle, slaughtering approximately 172,000 per year.
These cows have a high likelihood of being infected compared to other cattle because they have the most chance of being given feed containing mad-cow-infected tissue and they are old enough for the disease to have run its two- to eight-year incubation course. The cow in Washington that tested positive last December was an older dairy cow, and the cow that tested positive in Canada in May of 2003 was an older cow...
It's an undiagnosable disease in humans...until autopsy.
Research studies have found up to 13% of Alzheimers cases are misdiagnosed cases of Creutzfeldt-Jakob disease:
For humans, a new scare linked to beefDecember 19, 2004 Atlanta Journal-Constitution by DAVID WAHLBERG
Despite what federal health officials have said, a fatal illness similar to human mad cow disease could also come from eating meat, according to new studies.
The studies, from Europe, follow other research suggesting the illness may be more widespread than officials say, possibly accounting for some misdiagnosed cases of Alzheimer's disease.
The unsettling claims resonate after last month's mad cow scare, when a cow that would have been the nation's second known to have the disease eventually tested negative, after two preliminary positive tests. And locally, the illness similar to human mad cow gained attention in September, when more than 500 patients at Emory University were told they may have been exposed by surgical instruments used on an infected patient.
Both human conditions are known as Creutzfeldt-Jakob disease. A form called "variant" CJD, the known human version of mad cow, comes from infected cattle. Health officials say the other form, "sporadic" CJD, occurs spontaneously and does not occur in beef.
Both are fatal and have similar symptoms: loss of balance, memory and mental control. Variant CJD has killed about 150 people in Great Britain and a few in other countries since 1995. Sporadic CJD is thought to claim about 300 Americans a year.
The new European studies say beef could cause some cases of sporadic CJD...
Another puzzle complicating the CJD picture: autopsy studies. Some suggest that up to 13 percent of people diagnosed with Alzheimer's disease while alive may actually have CJD. Alzheimer's has similar symptoms, though the progression of the illness is usually longer.
A study in 1989 by Dr. Laura Manuelidis, chief of brain pathology at Yale University, found that six of 46 cases, or 13 percent, thought to be Alzheimer's were proved upon autopsy to be CJD. A similar study the same year at the University of Pittsburgh found that three of 54 patients, or 6 percent, diagnosed with dementia had CJD.
