• Specifies reagents, calibration protocols, validation, sample preparation, extraction, cleanup, and detection
• Requires analytical equipment capable of high sensitivity and selectivity: HPLC-MS/MS with electrospray ionization
• Emphasizes method validation, precision parameters (repeatability and reproducibility), and detection/quantification limits
• Laboratories must use certified reference materials for calibration and regularly verify accuracy using internal standards

Who should comply:

• Food laboratories, processors, slaughterhouses, aquaculture and fishing companies, regulatory and inspection agencies

Notable implications:

• Aligns with stringent food safety regulations and international trade requirements regarding veterinary residues
• Enhances consumer safety and confidence by supporting reliable, confirmatory analysis of residues
• Supports rapid response in case of non-compliance findings and risk-based surveillance

Key highlights:

• Multi-residue, multi-matrix detection capability in one analytical run
• Demonstrates high precision at trace (low μg/kg) concentrations in complex food matrices
• Complements regulatory Maximum Residue Limit (MRL) enforcement

• Introduces two validated heating procedures: 106 °C (30 min, autoclave) and alternative 100 °C (30 min, water bath)
• Specifies culture media composition, pouring/spread plating, incubation at 55 °C (48 h), and enumeration protocols
• Ensures differentiation between procedures in test reporting for clarity

Who should comply:

• Dairy manufacturers, microbiological laboratories, food safety auditors, and regulatory bodies

Notable improvements:

• Provides flexibility and harmonization for different laboratory capacities worldwide
• Directly supports quality control, shelf-life determination, and product safety, as spores can cause spoilage and potential health risks

Key highlights:

• Dual heating options increase feasibility and accuracy
• Spore enumeration methods are aligned with international food microbiology best practices
• Results guide cleaning, sanitation, and raw material selection in dairy plants
