Ochratoxin: Monitoring and analysis
Importance of monitoring ochratoxin A (OTA)
Ochratoxin A (OTA) is a mycotoxin produced by mold fungi of the Aspergillus and Penicillium species. OTA poses significant health risks to humans and animals due to its nephrotoxic, hepatotoxic, teratogenic, carcinogenic, and immunosuppressive properties.
Common sources and effects of ochratoxin
Ochratoxin A is predominantly found in grains, nuts, legumes, coffee, spices, and dried fruit if these foods were not sufficiently dried before storage. However, it can also contaminate animal products, as the toxin accumulates in the organs of animals fed contaminated feed, leading to significant economic losses in livestock. OTA has been detected in pigs’ blood and kidneys, as well as in human blood and breast milk. In humans, OTA is associated with Danubian endemic familial nephropathy, a condition prevalent in regions with high OTA concentrations in grains and cereals.
Regulatory compliance and consumer protection
Ochratoxin limit values are established for a broad range of foods. Specifically, for pepper products (including chili powder, cayenne pepper, and paprika seasoning), the limit value was initially set at 30 μg/kg and later reduced to 15 μg/kg. Regular monitoring and analysis are essential to ensure that food products comply with these limits and protect consumer health.
Analytical solutions for ochratoxin detection
The R-Biopharm Group has over 20 years of experience in researching and producing mycotoxin test kits, offering various test formats to meet the food industry’s needs. These include:
- RIDASCREEN® ELISA tests: For the screening and quantification of ochratoxin A in different samples.
- OCHRACARD® screening cards: For rapid detection of ochratoxin A.
- Immunoaffinity columns (OCHRAPREP®): Used with HPLC to purify complex and strongly colored food samples, such as spices. This process concentrates the mycotoxin to achieve highly sensitive and accurate test results.
Key benefits of ochratoxin monitoring
- Consumer protection: Ensures food products are safe for consumption by detecting and quantifying ochratoxin contamination.
- Animal health: Protects livestock from the adverse effects of OTA-contaminated feed, improving animal welfare and productivity.
- Regulatory compliance: Helps manufacturers comply with food safety regulations, preventing legal and economic repercussions.
- Quality assurance: Maintains the integrity and safety of food products by preventing the distribution of contaminated items.
- Advanced detection methods: Utilizes reliable and efficient analytical platforms for the accurate monitoring of ochratoxin levels in various food products.
Conclusion
Monitoring ochratoxin A (OTA) is crucial for protecting human and animal health, ensuring regulatory compliance, and maintaining the quality of food products. By employing advanced detection methods, manufacturers can accurately identify and quantify OTA contamination, ensuring the safety of their products. This proactive approach supports robust quality control processes, upholds food safety standards, and fosters consumer trust in food products.
