Many businesses believe that simply "taking samples for testing" is enough to complete their legal documentation. However, in reality, more than 60% of penalty cases belong to the group that had already performed testing, but... used the wrong technical standards, tested the wrong parameters, or followed the wrong process. This leads to wasted time, unnecessary costs, and even product recalls.

This article analyzes the 7 most dangerous food testing mistakes and how VNTEST helps businesses resolve them completely, ensuring compliance with legal requirements, technical standards, and parameters right from the start.

Why Are Businesses Still Fined After Testing?

Because many businesses misunderstand the true nature of testing. Testing is not just about "having a result," but achieving the right parameters – the right result format – the right standard – at the right time.

Here are the 7 critical mistakes:

7 Food Testing Mistakes That Lead to Business Fines

Error 1: Selecting the wrong set of parameters → Invalid results despite passing

This is the most common error. Each product group has different legal requirements:

• Beverages → microbiology + heavy metals + toxins
• Meat & Seafood → E. coli, Salmonella, histamine...
• Functional Foods → active ingredients, heavy metals, stability...

Selecting the wrong parameters renders the results void in the self-declaration dossier during inspections.

VNTEST: Advises on custom parameter sets precisely tailored to Decree 15/2018, QCVN, Codex, and industry-specific requirements.

Error 2: Incorrect sampling → Results do not reflect reality

Some facilities collect samples arbitrarily without representing the production batch. This causes:

• Skewed results
• Rejection during self-declaration
• Fines for violating dossier truthfulness

VNTEST: Supports sampling in accordance with ISO 17025 standards and traceability regulations.

Error 3: Failure to retain control samples

In practice, many facilities do not retain control samples for 2–4 weeks after testing. When disputes arise, there are no samples available for cross-checking.

VNTEST: Guides standard-compliant sample retention procedures.

Error 4: Confusing "Testing" with "Product Declaration"

Many businesses mistakenly assume:

• Testing: Only proves product safety.
• Declaration: A dossier containing 6–9 other documents.

Misconception → submitting incorrect files → rejected → delays in product launch.

Error 5: Using test results from labs without ISO 17025 accreditation

Some testing laboratories lack ISO 17025 competency assessment systems. → Results are not accepted during inspections or declaration filings.

VNTEST: Direct partner of ISO 17025 accredited laboratories with nationwide validity.

Error 6: Test results lack the correct legal format

Common defects include:

• Missing signature of the testing expert
• Missing parameter codes
• Missing test methods
• Incorrect reference standards (QCVN, TCVN)

Inspectors will rate these results as "invalid".

VNTEST: Performs a 2-tier review before returning results.

Error 7: Using expired test results

Many product groups require periodic testing every 6–12 months. Once expired, unexpected inspections will incur fines.

VNTEST: Continuously provides periodic testing notifications to help businesses avoid compliance risks.
