Quality & Supply / Frozen Edamame HACCP Case Study

From IQF, the plan describes bulk weighing and frozen storage, and a route through final bagging, seal and weight recheck, metal detection, cartoning, storage and shipment. The diagrams also show a branch from bulk frozen storage to dispatch. The detector location and coverage for that branch need to be established against the site's controlled flow and records.

Packaging starts before the finished bag reaches the line. The case calls for checks on bag and carton condition, supplier documentation and print. It also describes municipal water and chilled water for washing and cooling and separate handling of edible salt. The complete route and specification notes are below. Explore frozen edamame forms.

Read the worksheets against the approved flow for the relevant edamame route. Each entry names a hazard, gives the reason for its classification and identifies the control the site relies on. Water, sanitation, personnel hygiene, maintenance, pest control and material handling underpin the analysis. FAO hygiene and HACCP toolbox.

Trace a physical finding to the step and control that address it. Sorting can remove field material, an equipment check can identify loose parts, and a detector addresses metal fragments within its validated capability. A damaged bag seal calls for a separate packing check.

Ask for validation to see why the chosen control suits the product and the line. Look at the run record to see whether the operator met the required condition. Verification records show how the site reviewed monitoring, instruments and corrective action.

The two worksheets consider biological, chemical and physical hazards step by step. They group soy under chemical hazards in the source. Soy identity, segregation and the declared allergen need to be reviewed for the actual product and any shared line. The worksheets record the reason for a significance decision and the control relied on for that step. A dash represents an empty source field. A classification describes this case and its route.

A significant hazard can be addressed at another step or through a prerequisite programme, depending on the site's analysis. For example, loose metal may be considered in sorting or cooling even though the detector is recorded later. An entry for a water or seal hazard identifies the control used there without changing the CCP schedule.

Controls, monitoring and corrective action

The case summary identifies three CCPs. The responsible site confirms the current limits and monitoring instructions for the product and route.

Basis cited for the case limits

The stated bases help identify which technical and order documents to request for the applicable site.

The salted worksheet also lists a brine-heating control as CCP2a. The kernel worksheet identifies a separate disinfectant concentration and contact-time control as CCP2b. Both need reconciliation with the issued CCP schedule before assigning either to a current production route. For metal detection, the schedule and descriptions must agree on the challenge materials, frequency, reject check and where the bulk route is screened.

The case cites destination requirements, experience or verification and equipment capability in its basis for limits. The current site supplies the validated critical limit and its monitoring instruction. The buyer's specification or applicable market criteria supply the separate product acceptance conditions. Keeping those references distinct helps reviewers see which requirement applies when a result or a reading is out of range.

1. Identify and isolate. Mark the time, line, product and lot. Secure the rejected pack or place the affected production on hold. Use the last acceptable challenge, the process record and pack codes to establish the boundary, then widen it if the evidence requires.
2. Restore and check the control. Investigate the alarm or test failure, including equipment condition and the reject system. Document any adjustment or repair. Verify the detector and rejection response with the site's approved test pieces and pack setup before relying on the line again.
3. Decide what to do with the held product. The authorised quality role evaluates the affected quantity and decides whether approved re-screening, rework, rejection or disposal applies. Record the decision, the resulting lot status and the evidence needed for release.
4. Match the disposition to the order. Where the affected lot belongs to a GreenLand order, we reconcile the factory decision against the lot codes, quantities and shipment file. If product has already moved, the processor and relevant parties use the traceability and notification procedure for that event.

This record lets a buyer ask a precise question after seeing a COA or a release note. Which units did the investigation cover? The answer should name the production interval and the resulting carton or pallet range so the receiving team can identify any goods that remain on hold.

For an audit, include the legal site, product form and activities in the certificate scope review. Ask which records can be supplied for the specific lot and whether anything in the buyer's approval requires a site review or a third-party inspection. If an input, label or lot code changes, the order file needs a clear link to the revised approval so the receiving team can follow it.

Send us the specification or label and the checks your quality team wants to see. For a shipment already received, a photo of the carton mark and the quantity affected will help us identify the packing batch and the records behind it. Review factory audit and inspection support.
