Summary

FSSAI Registration is an important part of operating a food business, but maintaining food safety also involves proper identification and traceability of food products. Coding systems are used in food processing and packaging operations to print or mark information such as batch numbers, manufacturing details, expiry or best-before information, and other required product identification details.

A coding system must be managed carefully because incorrect, unclear, or missing information can create problems during product tracking and distribution. Regular equipment cleaning, verification, maintenance, and record keeping can help food businesses maintain reliable coding practices.

Introduction

Food products often pass through several stages before reaching consumers. During production, processing, packaging, storage, and distribution, businesses need a reliable way to identify individual batches or lots.

Coding systems help businesses assign and print identification information on food packaging or labels. Depending on the product and packaging method, businesses may use inkjet printers, laser coders, thermal printers, or other suitable coding equipment.

Proper coding is not only a packaging activity. It also supports product traceability and helps businesses identify specific batches when investigating complaints, quality issues, or product withdrawals.

After obtaining FSSAI Registration, food businesses should establish suitable procedures for creating, checking, and maintaining product codes.

What Is a Food Processing Coding System?

A food processing coding system is a method used to apply identifying information to food packaging or products.

The information may include:

• Batch or lot number

• Manufacturing date

• Best-before or expiry information, where applicable

• Product identification code

• Production shift information

• Other relevant traceability details

The exact information and format depend on the product, packaging, and applicable regulatory requirements.

Why Proper Coding Management Is Important

A well-managed coding system helps businesses:

• Identify individual batches

• Support product traceability

• Reduce identification errors

• Assist stock management

• Support product withdrawal or recall activities

• Provide clearer information on packaged products

Incorrect coding can create confusion and may make it difficult to identify affected products during a food safety investigation.

Establish a Clear Coding Procedure

Food businesses should have a documented procedure explaining how product codes are generated and applied.

The procedure should identify:

• Who is responsible for coding

• How codes are created

• Where codes are applied

• How codes are verified

• What happens when an error is detected

• How coding records are maintained

A clear procedure reduces the possibility of employees using incorrect codes during production.

Verify the Correct Product Code

Before starting a production run, employees should verify that the coding machine contains the correct information.

The verification should compare the machine settings with the approved production information.

Employees should check:

• Product name

• Batch or lot number

• Date information

• Coding format

• Packaging material

• Production details where applicable

This simple check can help prevent incorrect information from being printed across a large quantity of products.

Check Code Legibility

Printed information should remain reasonably clear and readable.

Businesses should monitor for:

• Faded printing

• Missing characters

• Smudged codes

• Incorrect alignment

• Incomplete printing

• Uneven application

Poor-quality codes can make product identification difficult and may affect traceability.

Maintain Coding Equipment Hygiene

Coding equipment should be maintained in a hygienic condition, especially where the equipment operates close to exposed food products.

Businesses should prevent:

• Ink or chemical spills

• Dust accumulation

• Product residue buildup

• Unnecessary contact with food

• Contamination around packaging areas

Cleaning should be performed according to the equipment manufacturer's instructions and the food business's hygiene procedures.

Handle Coding Materials Carefully

Coding systems may use inks, cartridges, solvents, ribbons, or other consumables depending on the technology.

These materials should be stored and handled appropriately.

Businesses should:

• Keep materials in suitable storage

• Prevent accidental spills

• Keep containers properly closed

• Follow supplier instructions

• Prevent unnecessary contact with food and packaging surfaces

Only materials suitable for the intended application should be used.

Prevent Wrong-Batch Coding

One of the important risks in product coding is applying information from a previous production run to a new batch.

Before changing production batches, employees should verify and update the coding information.

A suitable changeover procedure can include:

1. Stop the previous production run.

2. Remove or isolate remaining packaging material.

3. Update the coding information.

4. Verify the new code.

5. Print a test sample.

6. Approve the sample before full production.

This helps reduce the chance of carrying an old code into a new production batch.

Conduct Regular Code Verification

Coding should not be checked only at the beginning of production.

Businesses should establish suitable verification intervals during the production run.

Employees can check samples for:

• Correct batch information

• Date details

• Code readability

• Correct position

• Consistent printing

Additional checks may be required after machine adjustments, material changes, or production interruptions.

Manage Coding Errors

If an incorrect code is identified, the affected products should be identified and controlled according to the business's corrective-action procedure.

The business should determine:

• When the error started

• Which products were affected

• How much product may be involved

• Whether incorrect products have already been dispatched

• What corrective action is required

Records should be maintained for significant coding errors and corrective actions.

Maintain Traceability Records

Coding systems are closely connected with product traceability.

Businesses should maintain suitable records connecting product codes with relevant production information.

Records may include:

• Production date

• Batch or lot number

• Product details

• Quantity produced

• Packaging information

• Distribution details where applicable

Good records can make it easier to identify products if a safety concern arises.

Maintain Coding Machines Properly

Coding machines should be included in a preventive maintenance schedule.

Maintenance may include:

• Cleaning print heads

• Checking printing quality

• Inspecting cables and connections

• Replacing worn components

• Checking sensors

• Cleaning external surfaces

• Servicing equipment according to manufacturer instructions

Regular maintenance helps reduce unexpected coding failures.

Train Employees

Employees responsible for coding operations should receive suitable training.

Training can cover:

• Code-setting procedures

• Batch changeover

• Verification checks

• Equipment cleaning

• Handling coding materials

• Error reporting

• Record keeping

Employees should understand the importance of checking codes before and during production.

Keep Coding Areas Organized

The area around coding equipment should be kept clean and organized.

Unnecessary packaging materials, old labels, unused coding information, or discarded samples should not be left around the workstation where they could cause confusion.

Clear organization can help employees distinguish current production materials from items belonging to previous batches.

Use Sample Checks During Production

Businesses can retain appropriate coding samples as part of their internal verification process.

Samples may help demonstrate:

• What code was applied

• Whether the printing was legible

• Whether the correct information was used

• Whether coding remained consistent during production

The business should determine an appropriate sampling frequency based on its operations.

Maintain Proper Records

Coding-related records should be maintained according to the food business's documentation system.

Records can include:

• Code approval records

• Verification checks

• Coding machine maintenance

• Cleaning activities

• Coding errors

• Corrective actions

• Employee training

Proper documentation provides evidence that coding controls are being followed.

Common Coding Problems to Watch For

Food businesses should monitor for:

• Incorrect batch numbers

• Wrong date information

• Faded printing

• Missing characters

• Smudged codes

• Incorrect code placement

• Old codes remaining after changeover

• Coding machine failures

Problems should be addressed as soon as they are identified.
