Mad cow disease, scientifically known as Bovine Spongiform Encephalopathy (BSE), is a neurodegenerative disease that affects cattle. It is caused by abnormal proteins called prions, which gradually accumulate in the brain and nervous system, leading to severe neurological symptoms.
Humans can contract a variant of this disease known as variant Creutzfeldt-Jakob Disease (vCJD) by consuming contaminated beef products from cattle infected with BSE. vCJD is a rare and fatal brain disorder, and it has been linked to the consumption of infected cow parts, particularly those containing nervous tissue (such as the brain and spinal cord).
To prevent the spread of BSE and protect public health, extensive measures have been implemented in many countries:
- Banning Risky Feed Practices: Many countries have banned the use of certain types of animal proteins in cattle feed, as these practices were a major source of BSE transmission.
- Surveillance and Testing: Regular surveillance and testing of cattle for BSE are conducted to detect and isolate infected animals.
- Culling Infected Animals: Infected animals and those suspected of being infected are culled to prevent the spread of the disease within the cattle population.
- Stringent Regulations and Inspection: Strict regulations and inspection procedures are in place for the slaughter and processing of cattle to ensure that infected animals do not enter the human food chain.
Given these measures, the risk of contracting vCJD from eating beef in regions with well-implemented control measures is extremely low. However, it's important to follow food safety guidelines and consume beef from reputable sources that adhere to the established regulations.
If you have concerns about BSE, you may also want to stay informed about any advisories or recommendations provided by local health authorities or food safety agencies in your region.
