Understanding BSE and TSE: Impacts, Regulations, and Compliance in the Global Market

This blog explores the nature of BSE and TSE, the regulations put in place to manage their risks, and what businesses and manufacturers must do to remain compliant and safeguard public health.

BSE and TSE

What Are BSE and TSE?

Bovine Spongiform Encephalopathy (BSE), commonly known as “mad cow disease,” and other Transmissible Spongiform Encephalopathies (TSEs) are prion diseases that have impacted global agriculture, trade, and consumer safety.

Transmissible Spongiform Encephalopathies

TSEs are a group of progressive, fatal diseases affecting the brain and nervous system in humans and animals. These diseases result in long incubation periods and neurodegenerative symptoms, ultimately leading to death. Prions, the infectious proteins responsible for TSEs, alter the structure of normal proteins in the brain, causing them to accumulate in abnormal forms that damage brain tissue.

Key types of TSEs include:

  • Bovine Spongiform Encephalopathy. BSE affects cattle. It first emerged in the United Kingdom in the 1980s and caused widespread panic and economic loss due to fears of transmission to humans.
  • Creutzfeldt-Jakob Disease. CJD is a rare, fatal brain disorder in humans.
  • Scrapie: Affects sheep and goats and has been recognized for centuries.
  • Chronic Wasting Disease. CWD primarily affects deer and elk and has been detected in parts of North America.

Of particular concern is Variant Creutzfeldt-Jakob Disease (vCJD), a form of CJD believed to be caused by consuming meat contaminated with BSE prions. This form of TSE in humans first came to light during the BSE crisis, raising alarms about the potential zoonotic (animal-to-human) transmission of prion diseases.

How BSE and TSE Impact Industries

BSE and TSE outbreaks can significantly impact both the agricultural and food industries. The emergence of BSE led to:

  1. Economic Losses: Outbreaks prompted mass culling of livestock, trade bans, and food destruction, resulting in substantial financial damage.
  2. Trade Restrictions: Countries closed their markets to cattle and beef products from regions with confirmed cases, limiting international trade.
  3. Shift in Consumer Preferences: An increased demand for plant-based foods and organic products followed the initial BSE crisis due to consumer concerns about meat safety.
  4. Increased Regulatory Scrutiny: Industries from pharmaceuticals to electronics faced heightened oversight due to the potential use of animal-derived ingredients.

Due to the risk of zoonotic transmission, industries utilizing animal by-products – such as pharmaceuticals, cosmetics, and medical devices -must adhere to strict guidelines to prevent prion contamination.

BSE and TSE Risks in the Electronics Industry

Although not typically associated with prion diseases, the electronics industry faces indirect risks from BSE/TSE due to animal-derived materials in some electronic components and manufacturing processes.

Animal-based substances, such as gelatin (used in certain adhesives or coatings) or tallow (used as a processing agent in circuit boards), can pose potential prion contamination risks if sourced from BSE-affected animals.

As a result, electronics companies are increasingly scrutinizing their supply chains. Further, they opt for alternative, synthetic materials to avoid regulatory and health-related issues.

Compliance with BSE and TSE regulations is crucial, especially for companies exporting to regions with stringent animal product regulations. Indeed, failure to meet these standards can restrict market access and damage brand reputation.

Therefore, electronics manufacturers are encouraged to perform thorough risk assessments and maintain transparent documentation for animal-derived materials used in their products to ensure safety and regulatory compliance.

Regulatory Landscape Surrounding BSE and TSE

To control the spread of BSE and TSEs, regulatory bodies across the globe have implemented several key measures:

  1. Prohibition of High-Risk Animal Material in Feed: One of the most significant sources of BSE spread in cattle was through animal feed containing meat and bone meal from infected animals. Regulations now ban such high-risk materials in animal feed to prevent prion transmission.
  2. Strict Slaughterhouse Practices: Guidelines dictate that producers must remove and properly dispose of animal tissues with the highest prion concentrations. For instance, it is the case of the brain and spinal cord. Therefore, in many countries, the slaughter and processing of animals are closely monitored to prevent cross-contamination.
  3. Surveillance and Testing Programs: Surveillance programs test cattle and other susceptible animals for signs of BSE. In the European Union, for example, cattle over a certain age must undergo testing for BSE.
  4. Traceability and Record-Keeping: Regulatory frameworks require comprehensive livestock tracking from birth to slaughter. This traceability allows for faster response and containment of any outbreaks and is critical for international trade compliance.
  5. International Standards and Trade Compliance: Organizations like the World Organisation for Animal Health (OIE) inform on animal health and food safety, which member countries follow to establish BSE-free certifications. Compliance with these standards enables countries to engage in the international trade of animal products.
  6. Controls on Animal-Derived Materials in Non-Food Products: As stated above, TSE risks are not limited to food. Regulations in industries such as pharmaceuticals, cosmetics, and medical devices control the use of animal-derived ingredients, especially in products that could be ingested or implanted.

Compliance Challenges and Best Practices

Industries that manufacture products containing animal-derived materials face stringent compliance requirements. To manage BSE and TSE risks effectively, companies must adopt the following best practices:

  1. Supplier Audits: Conducting regular supplier audits ensures that animal-derived ingredients come from BSE-free sources. Supplier transparency and adherence to international standards are essential in establishing a secure supply chain.
  2. Documentation and Traceability: Maintaining detailed records for all animal-derived materials used in products is crucial. Importantly, proper documentation not only satisfies regulatory requirements. It also supports swift recalls or investigations if necessary.
  3. Risk Assessments: Companies should conduct regular risk assessments of their products to identify potential contamination risks. Risk assessments should consider the geographic origin of materials, the potential for cross-contamination, and the level of processing.
  4. Regulatory Updates: Given the evolving nature of BSE and TSE regulations, companies must stay informed about regulatory changes in all regions where they operate or trade. Compliance teams need to track any new developments and adapt protocols as necessary.
  5. Product Testing: Some industries, particularly pharmaceuticals, may require rigorous testing for animal-derived ingredients to rule out prion contamination. Although prion detection remains challenging, new diagnostic methods are under development to increase safety.
  6. Consumer Communication: Clear labeling and communication about animal-derived materials can build trust with consumers. During a crisis, timely communication and transparency can mitigate reputational damage.

BSE and TSE Compliance in Different Industries

  1. Pharmaceuticals and Medical Devices: Animal-derived materials in drugs and medical devices are highly regulated. For example, the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) impose strict standards to prevent prion contamination in pharmaceuticals.
  2. Cosmetics and Personal Care: In the cosmetics industry, regulations restrict certain animal-derived ingredients from potential TSE risks. Manufacturers must verify that these materials come from countries with low or no BSE risk.
  3. Food and Agriculture: Food industries face direct regulations on slaughterhouse practices, feed composition, and food processing. Compliance with these measures is critical for market access and consumer trust.

Conclusion on BSE and TSE

The impact of BSE and TSEs has reshaped industries and prompted stringent regulatory frameworks to manage prion risks. For businesses, compliance is not only a matter of regulatory necessity. It is also essential for maintaining consumer trust and accessing global markets. By adopting best practices in supplier auditing, risk assessment, traceability, and transparency, companies can mitigate the risks associated with BSE and TSEs. These measures are integral to ensuring safety and enhancing resilience in industries reliant on animal-derived materials, providing the necessary safeguards to prevent another widespread crisis like the BSE outbreak of the 1980s.
BSE and TSE regulations remind us of the need for vigilance and responsibility in industries that handle animal products. With ongoing advancements in prion research, diagnostic technology, and regulatory policies, companies have better tools than ever to protect public health and uphold compliance.
