United Kingdom registers atypical case of mal da vaca louca, reports health authority

The United Kingdom registered an atypical case of Bovine Spongiform Encephalopathy (BSE)doença known as mal da vaca louca, in a 17-year-old milk cow, according to the World Organization for Animal Health (OIE).

Secondly, the organ, the animal has not been killed and investigations are underway in the region where the cow was found.

The exact location of the farm was not included in the report to protect the identity and well-being of the farmer, second to entity.

The OIE also affirms that the registration of this case does not alter the risk status of EEB in the United Kingdom.

In February of this year, a diagnosis of pain was confirmed in Brazil.

An examination carried out in a reference laboratory in Canada confirmed that it was an atypical infection.

At the time, China was forced to suspend the export of meat.

What is the lady of the crazy cow

TO Bovine Spongiform Encephalopathy (BSE) It is a disease of the bovine nervous system, which has a long incubation period between two and eight years, and occasionally longer. Currently there is no treatment or vaccine against the aggravation.

It is part of a group of diseases known as transmissive spongiform encephalopathies, or diseases caused by prions, characterized by a non-nervous accumulation of an abnormal infectious protein called a prion. This group included a variant of the Creutzfeldt-Jakob pain, which affects humans.

Classical BSE was first diagnosed in cattle in the United Kingdom in 1986, but was probably present in the country’s cattle population since the 1970s or earlier, according to the World Organization for Animal Health (OIE). Later, it was reported in 25 countries other than the United Kingdom, mainly in Europe, Asia, the Middle East and North America.

Currently, as a result of the recently successful implementation of effective control measures, the prevalence of classical BSE is extremely low, as well as its global health impact and risk to public health.

The doença can be divided in two ways, according to OIE. The classic version occurs through the consumption of contaminated food. Although the classic form has been identified as a significant threat in the 1990s, its occurrence has decreased sharply in recent years, as a result of the recently implemented effective control measures, and is now estimated to be extremely low.

The atypical version refers to forms of natural and sporadic occurrence, which are credited to occur in all bovine populations at a very low taxa and which are only identified in older bovines during intensive surveillance.

In the early 2000s, atypical prions causing atypical louca foram were identified as a result of increased surveillance for transmissive spongiform encephalopathies. The number of atypical and insignificant cases, according to OIE.

In fact, even at this time there is no evidence that the atypical version is transmissible, the ‘recycling’ of the atypical crazy cow agent was not ruled out and, therefore, measures to manage the risk of exposure in the food chain continue to be recommended as precautionary measure.
