Tannery Waste and the Production of Gelatine: A Hazard to Health and Food Safety
Tannery Waste: Definition and Origins
Tannery waste refers to by-products generated during the leather tanning process, including animal hides and skins, chemical residues, and other organic materials. These waste products are often used in the production of gelatine, a common ingredient used in food, pharmaceutical, and cosmetics.
Health Risks Associated with Tannery Waste
The use of tannery waste in gelatine production poses significant health risks due to the presence of hazardous chemicals like chromium and other heavy metals. According to Dr. Farah Ayuni Shafie, an associate professor with Universiti Teknologi Mara, gelatine derived from tannery waste often has quality inconsistencies, making it challenging to meet the stringent standards required for food and pharmaceutical applications.
Cross-Contamination and Halal Certification
Poor storage management and a lack of microbiological control in gelatine production can lead to contamination with harmful bacteria and fungi, resulting in foodborne illnesses, allergic reactions, and respiratory problems. Cross-contamination can also introduce allergens and non-halal substances into the gelatine, violating halal requirements. In addition, improper storage can degrade gelatine quality, making it unfit for consumption and reducing its functional properties.
Call for Standardization and Regulation
Dr. Shafie recommended that regulatory bodies standardise criteria and implement detailed guidelines for the halal certification processes. Regular inspections and comprehensive audits by third-party auditors can ensure strict compliance. Strict penalties for non-compliance and public disclosure of violations can also deter fraudulent practices.
Conclusion
The use of tannery waste in gelatine production poses significant risks to human health and food safety. It is crucial that regulatory bodies take immediate action to standardise the halal certification process and ensure the QA/QC of gelatine production. By doing so, we can ensure that the gelatine used in our food and pharmaceuticals is safe and fit for consumption.
