A rare fount of insane moo-cow disease , also have it away as bovine spongiform encephalopathy ( BSE ) , has been find at a debacle plant in South Carolina but personate no threat to humans or other cattle . It is only the seventh confirmed lawsuit of the highly deadly disease ever recorded in the U.S.
Officials from the U.S. Department of Agriculture ( USDA ) announced the discovery in astatementreleased May 19 . A 5 - year - old beef cow belong to a ruck from Tennessee tested overconfident for BSE after being deem unfit for slaughter and undergo routine testing .
Mad cow disease is a deadly neurological disorder that impacts cattle.
" This animal never entered slaughter canal and at no clip represent a risk to the food provision or to human wellness in the United States , " USDA representatives wrote in the statement . An investigating into the exact movement of the contagion is ongoing , but it is likely an stray casing , they added .
BSE is a progressive neurological disorder of Bos taurus because of proteins called prions ; prions are found on the surface of electric cell , but in diseases like mad cow , theseproteins fold abnormallyand can get other , sizeable prions to do the same . In BSE , the prions involve proteins in the brain and central queasy system , cause a range of symptom , let in behavioral changes , coordination problem , weight departure , decreased milk output and eventually , death , concord to theUSDA .
There are two forms of BSE : classic BSE , which develops when a moo-cow take in taint fabric , such as core or off-white meal , made from an infected moo-cow in their feed ; and untypical BSE , which develops spontaneously in older cows . The recently diagnose cow had untypical BSE , which poses less of a concern for animate being welfare official .
Classical BSE is transmitted to cattle when they eat materials from infected cows in their feed.

Atypical vs. classical BSE
Both definitive and atypical BSE are triggered by prions , but each of the two form has a unique prion structure and is touch off in dissimilar ways .
Classical BSE was first discovered in 1986 in the U.K .. The BSE irruption peak there in January 1993 , when guinea pig spiked to around 1,000 a week , concord to theCenters for Disease Control and Prevention .
Scientists finally discovered that the prion were being channelize through the cows ' feed , which hold in infected head and spinal tissue paper left over from the butchering of the animals . In 1997 , the U.S. Food and Drug Administration ( FDA ) ostracize the use of employment of ruminant — a group of hoofed , herbivorous grazing mammal that includes cattle , bison , goats , sheep and deer — protein in feed for other ruminants , and it later on prohibited the utilization of sure high - risk of infection cattle tissues in feed for all animals , accord to the USDA .
Cattle feed no longer contains any ruminant material to prevent outbreaks of classical BSE.
irregular BSE appears to sometimes make spontaneously in Bos taurus that are unremarkably former than 8 years , which makes the disease ’s outgrowth in a 5 - twelvemonth - old moo-cow strange . It is presently indecipherable what touch off untypical BSE .
It can take three to six years for the symptoms of either BSE manakin to come along after infection , and there is presently no therapeutic or vaccine for the disease , accord to USDA .
Can humans get mad cow disease?
Humans can not get BSE directly , but they can rise a similar and as virulent eccentric of prion disease have it away as Creutzfeldt - Jakob disease ( vCJD ) by eat food products made from infected cattle . vCJD causes symptoms similar to BSE and also lead in decease . However , it is extremely rarefied . As of 2019 , only 232 the great unwashed worldwide have ever been diagnose with vCJD , according to theFDA .

In an strange case , a lab technician in France died in June 2019 from vCJD afteraccidentally injecting herself with BSE prionsthrough her protective equipment as she was studying the disease in 2010 .
The World Organisation for Animal Health recognizes the U.S. as having paltry peril for BSE , and this new fount will not change that , USDA representatives wrote .
