In food and beverage production, a small coding or labelling error can quickly become a serious issue.

A missing use-by date, unreadable batch code, incorrect label, poor barcode, or undeclared allergen can lead to rejected stock, retailer complaints, product withdrawals and full recalls.

For manufacturers, the cost is not only financial. A recall can damage customer trust, interrupt production, create pressure on quality teams and put long-standing retail relationships at risk.

This is why more food and beverage manufacturers are using vision inspection systems to strengthen quality control on the production line.

Vision inspection helps check that the right information is applied to the right product before it leaves the factory.

What is vision inspection in food production?

Vision inspection uses industrial cameras, lighting, software and automated checking tools to inspect products, packaging, labels and codes as they move through the production line.

Instead of relying only on manual checks or occasional samples, a vision inspection system can check every product in real time.

In food and beverage production, vision inspection can be used to check:

• Batch codes
• Use-by dates
• Best-before dates
• 1D and 2D barcodes
• QR codes
• Label presence
• Label position
• OCR and OCV text
• Allergen information
• Product and packaging match
• Print quality
• Reject confirmation

The aim is simple: catch coding and labelling errors before products reach the customer.

Why coding and labelling errors create recall risk

Food and beverage packaging carries essential product information. Consumers, retailers, distributors and quality teams all rely on that information being accurate and readable.

If the wrong information is printed or applied, the consequences can be serious.

For example, if a batch code is missing or unreadable, it becomes harder to trace affected products during a quality issue. If a use-by date is missing or incorrect, products could be sold or consumed beyond the intended date. If a barcode does not scan properly, it can create problems in distribution, retail and stock control.

Allergen labelling is one of the highest-risk areas. If a product contains an allergen that is not clearly declared on the packaging, it can create a serious consumer safety issue.

The Food Safety Authority of Ireland regularly publishes food alerts involving product recalls, batch details, use-by dates and allergen issues. These alerts show how important accurate product identification and packaging information are in food safety.

Manual checks are still important, but they have limits. On fast-moving lines, people can become distracted, tired or under pressure. Packaging changeovers can be rushed. Labels can be loaded incorrectly. Printers can lose print quality. A small issue can affect a large number of products before anyone spots it.

Vision inspection gives manufacturers an extra layer of protection.

How vision inspection reduces recall risk

1. It checks every product, not just samples

Manual checks are often carried out at set intervals. This helps, but it does not guarantee that every product has been inspected.

A vision inspection system can check each product as it moves through the line.

This is especially useful on high-speed food and beverage lines where even a short error can affect hundreds or thousands of products.

By inspecting every item, manufacturers can reduce the risk of incorrect or non-compliant packaging leaving the production area.

2. It confirms that batch codes and dates are present

Batch codes, use-by dates and best-before dates are critical for traceability.

If there is a quality issue, the manufacturer needs to know exactly which products are affected. Clear, accurate and readable codes make this process much easier.

A vision inspection system can check that the correct code is present, in the right location and readable.

If a code is missing, badly printed, smudged, incomplete or in the wrong position, the system can trigger an alert or reject the product from the line.

This helps prevent products with poor or missing traceability information from reaching retailers or consumers.

3. It improves barcode and 2D code reliability

Barcodes are used throughout the supply chain, from production and warehousing to retail and stock control.

If a barcode does not scan correctly, it can cause issues with distribution, customer deliveries, stock handling or retailer acceptance.

Vision inspection can check barcode presence, quality and readability. It can also support the move towards 2D codes and QR codes, which are becoming more important for traceability, product data and future packaging requirements.

As more manufacturers prepare for greater use of 2D codes, barcode inspection will become even more important.

Printing the code is only one part of the process. Manufacturers also need confidence that the code can be read when it matters.

4. It helps prevent wrong label and wrong pack errors

One of the biggest risks in food production is applying the wrong label to the wrong product.

This can happen during changeovers, when similar packaging is used across multiple product variants, or when different flavours, recipes or private-label products are produced on the same line.

A vision system can help confirm that the correct label or packaging is being used for the product being produced.

This can include checks on label position, barcode, artwork, text, graphics or specific product identifiers.

For manufacturers producing multiple SKUs, this can significantly reduce the risk of wrong product, wrong label or wrong pack errors.

5. It supports allergen label checks

Allergen information must be accurate and clearly displayed.

If the wrong label is applied or allergen information is missing, the product may become unsafe for certain consumers.

Vision inspection can help by checking label details linked to allergen declarations, product variants or packaging artwork.

This is particularly useful where similar products are produced on the same line but contain different ingredients or allergens.

For food manufacturers, allergen label inspection can be a valuable safeguard against one of the most serious types of packaging error.

6. It reduces changeover mistakes

Many coding and labelling issues happen during product changeovers.

A line may switch from one product to another, but the printer settings, label roll, packaging film or production setup may not be changed correctly.

This can lead to the wrong code, wrong label, wrong date or wrong packaging being used.

Vision inspection helps catch these mistakes early. By checking the product, code or label against the expected setup, the system can identify mismatches before they become a larger production or recall issue.

This is especially useful for manufacturers with frequent changeovers, seasonal products, short production runs or multiple packaging formats.

7. It gives quality teams stronger control

Quality teams need confidence that products leaving the factory meet the required standard.

Vision inspection provides a more consistent approach to checking critical packaging and coding information.

Depending on the system, it may also provide image capture, reporting and production records. This can support audits, internal investigations, customer queries and continuous improvement.

Rather than relying only on manual checks, quality teams can use automated inspection as part of a stronger quality control process.

Where Codico’s Code Check system fits in

Codico’s Code Check code inspection systems are designed to help manufacturers verify codes, labels and product information directly on the production line.

Code Check can support a range of inspection requirements, including:

• 1D barcode checks
• 2D barcode checks
• OCR and OCV inspection
• Batch code verification
• Date code inspection
• Label position checks
• Allergen checks
• Product verification
• Packaging inspection
• Real-time production line inspection

The purpose of Code Check is to help manufacturers confirm that the right information is applied to the right product before it leaves the line.

This gives production, quality and engineering teams greater confidence in their coding, labelling and traceability processes.

Vision inspection should be built around the production line

No two production lines are exactly the same.

The right vision inspection setup depends on the product, packaging, line speed, code type, lighting conditions, printer type and quality requirements.

Before choosing a system, manufacturers should ask:

• What are the most common coding or labelling errors on the line?
• Which information is critical for traceability?
• Does the system need to check text, barcodes, labels or packaging?
• Is the line running at high speed?
• Are there frequent product changeovers?
• What should happen when a failed product is detected?
• Does the system need to reject products automatically?
• Is reporting or image capture required?
• Does the inspection system need to integrate with printers, labellers or other equipment?

The best system is not always the most complicated one. The best system is the one that solves the actual risk on the line.

Frequently asked questions about vision inspection in food production

What does a vision inspection system check?

A vision inspection system can check codes, labels, barcodes, printed text, packaging, product position and other quality points on the production line.

In food and beverage production, common checks include batch codes, use-by dates, best-before dates, label position, barcode readability and allergen information.

Can vision inspection prevent food recalls?

Vision inspection cannot remove every possible recall risk, but it can significantly reduce the chance of coding, labelling and packaging errors reaching the market.

By checking products automatically on the line, manufacturers can catch issues before products leave the factory.

Is vision inspection only for high-speed production lines?

No. Vision inspection can be useful on both high-speed and lower-speed lines.

It is particularly valuable where coding, labelling, traceability or allergen information is critical.

Can vision inspection check 2D barcodes and QR codes?

Yes. Vision inspection systems can be configured to check 1D barcodes, 2D barcodes and QR codes, depending on the application and inspection requirements.

This is becoming increasingly important as manufacturers prepare for wider use of 2D codes on packaging.

Why should manufacturers use automated inspection instead of manual checks?

Manual checks are useful, but they can be inconsistent on busy production lines.

Automated inspection provides a more consistent way to check every product, helping reduce the risk of human error, missed defects and incorrect packaging leaving the line.

Reducing risk before products leave the factory

Food and beverage manufacturers are under constant pressure to improve efficiency, protect consumers and meet customer expectations.

At the same time, product ranges are becoming wider, production lines are moving faster and packaging requirements are becoming more complex.

Vision inspection helps reduce recall risk by checking critical product information automatically and consistently.

It supports traceability, protects brand reputation, reduces manual errors and gives quality teams greater confidence that products are correctly coded and labelled before they leave the production line.
