Clean Labels, Clean Data: Digital Passports for Food
March 3, 2026
Sampling plays a critical role in food safety and quality control. However, improper sampling can easily lead to product contamination if procedures are not properly defined and implemented.
Because sampling involves direct contact with raw materials, finished products, or products in process, it is essential to follow clearly established procedures designed to prevent contamination.
Critical Requirements for Sampling
1. Documented Sampling Procedures
Food businesses must develop documented procedures for sampling incoming raw materials in a way that prevents contamination of the product.
These procedures should clearly define:
sampling methods
responsible personnel
sampling equipment
hygiene requirements
2. Proper Resealing of Packaging
Sampling often requires opening bags, boxes, or containers.
After sampling:
all openings must be properly resealed
packaging must be identified as opened and resealed
This ensures:
product protection
traceability
prevention of contamination
3. Prohibited Practices
Clips, staples, or similar objects must not be used to reseal packaging, as they can become a source of:
physical contamination
foreign body hazards
Processing Aids in Food Production
Processing aids are substances that come into direct contact with food during production.
Therefore, they must be handled carefully to avoid contamination or safety risks.
Examples include:
antifoaming agents
lubricants
processing oils
Critical Requirements for Processing Aids
1. Separate Storage
All processing aids should be stored separately from non-food materials to minimize contamination risks.
2. Proper Labelling
Processing aids must be properly labelled, indicating:
their intended use
application area
safety information
3. Supporting Documentation
Food facilities must maintain documentation confirming that processing aids are approved for use in food production.
This documentation may include:
technical data sheets
certificates of compliance
regulatory approval documentation
Proper sampling and correct management of processing aids are essential components of an effective HACCP system and help ensure high food safety standards.
