Product Issue Investigation

Practical product issue investigation support for New Zealand food businesses โ€” spoilage, mould, Listeria, foreign matter, packaging issues, customer complaints, root cause analysis and corrective actions.

Access Food Verification & Auditing Limited provides practical product issue investigation support for New Zealand food businesses.

Food product issues can affect food safety, product quality, customer confidence, audit outcomes and business reputation. When something goes wrong, it is important to act quickly, understand the issue, identify affected products, review possible causes and take suitable corrective actions.

We support businesses with structured product issue investigations, including onsite review, document and record review, environmental review, sampling plan support, laboratory coordination where required, root cause analysis support and corrective action recommendations.

Types of Product Issues We Can Help Investigate

  • Spoilage and mould growth
  • Yeast or fermentation issues
  • Microbial concerns
  • Listeria detection or environmental positives
  • Foreign matter complaints โ€” glass, metal, plastic, wood, rubber, pests
  • Texture, odour, taste or appearance defects
  • Packaging failures โ€” leaking, swollen, vacuum or gas-flush failures
  • Shelf-life failures
  • Allergen or cross-contact concerns
  • Incorrect label or packaging mix-ups
  • Customer complaints and product returns
  • Recurring product quality issues

Listeria Detection and Environmental Investigation

If Listeria is detected in a food production environment, a structured investigation is important to understand possible sources, spread routes and contributing factors.

Listeria investigation support may include:

  • Onsite investigation of affected areas
  • Review of where Listeria was detected
  • Review of environmental monitoring history
  • Identification of possible harbourage areas โ€” drains, floors, cracks, wet areas
  • Review of equipment design and dismantling practices
  • Review of cleaning and sanitation procedures and chemicals
  • Review of staff movement and traffic flow
  • Review of water, moisture and condensation risks
  • Support with targeted follow-up environmental swabbing plans
  • Coordination with accredited laboratories where testing is required
  • Root cause analysis support
  • Corrective action recommendations

It is not always possible to identify the exact source of Listeria. The aim is to identify possible sources, likely contributing factors and practical corrective actions to reduce recurrence risk.

Recall and Risk Assessment Support

Some product issues may require the business to assess whether affected product should be held, withdrawn or recalled. We can support businesses with gathering issue information, identifying affected products and batches, reviewing production and distribution records, supporting product hold decisions, traceability review and corrective action planning.

Food businesses remain responsible for notifying their verifier, MPI or New Zealand Food Safety where required. We provide investigation support, evidence review and practical guidance.
