What this is
What is a shelf life study record?
What is a shelf life study record?
It is the record of the study that establishes or extends a product's shelf life, covering which batches were tested, the storage conditions used, the test points scheduled, and the microbiological, chemical, sensory and physical criteria the product had to meet. It is carried out before launch and repeated on any change that could invalidate the existing study.
What makes a batch a worst-case batch for a shelf life study?
A worst-case batch is one produced under the conditions most likely to shorten shelf life within normal variation, such as the highest permitted moisture, the lowest permitted preservative level, or the longest permitted process time. Studying only a typical batch tells you how a typical batch behaves, not how the specification's edges behave, which is why the record scores worst-case inclusion separately from batch count.
How does a shelf life study record differ from a challenge test record?
A shelf life study observes how a product behaves under normal storage across its intended life and beyond, using the organisms and conditions the product would actually meet. A challenge test deliberately inoculates the product with the organism of concern to confirm the formulation or process controls it, and is triggered from within this record only when the study's own results call for it.
Scope
When is a shelf life study record required?
This record is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use this template when
- A new product is being launched and needs a shelf life established before it can be sold
- An existing shelf life is being extended, or a recipe, process, packaging or supplier change may have invalidated it
- A periodic revalidation of an existing shelf life is due
- You are running the Labelling and Packaging programme and this is one of its steps
- A linked record needs this one to exist: links product register, micro results
Do not use it for
- Challenge Test Record, which records a deliberate inoculation study to confirm the product controls the organism of concern across its life.
- Sensory Evaluation Record, which records a structured taste, smell and appearance assessment against a reference standard, rather than the full study design behind a shelf life decision.
- New Product Development Gate Review, which reviews a product at each development gate for food safety, legality, capability and shelf life before it moves on, of which this study is one input.
- Production Trial Record, which records a trial production run for process validation, not the storage study that follows it.
- Anything outside KnowQuality, which belongs in the workspace that owns that process
Compliance mapping
Which BRCGS cl.5.1 requirements does this satisfy?
BRCGS cl.5.1 requires shelf life to be established through valid, product-appropriate studies rather than assumption or precedent, and this record is built to show the design decisions that make a study defensible, not just its final conclusion.
| Clause | Requirement | Where it lands |
|---|---|---|
| BRCGS cl.5.1 | The product, study purpose and proposed shelf life are identified before testing begins | Header |
| BRCGS cl.5.1 | A minimum of three batches from different production days is studied, including a worst-case batch | Design |
| BRCGS cl.5.1 | Testing runs beyond the proposed shelf life and includes abuse conditions, not just storage to the stated date | Design |
| BRCGS cl.5.1 | Microbiological, chemical, sensory and physical criteria, including failure criteria, are agreed before testing starts | Criteria |
| BRCGS cl.5.1 | Each test point records an actual result against the agreed criteria rather than a bare pass or fail flag | Results |
| BRCGS cl.5.1 | The conclusion states whether the shelf life is supported, with the margin to failure recorded | Conclusion |
| BRCGS cl.5.1 | A restudy trigger tied to recipe, process, packaging or supplier change is defined alongside the next review date | Conclusion |
What it does not cover
- A single batch studied and treated as representative, which tells you how that one batch behaved and nothing about the range the specification actually permits.
- Test points that stop exactly at the proposed shelf life date, which confirms survival to that day but reveals nothing about the margin beyond it.
- Microbiological or sensory criteria agreed after the results were already in, which lets the pass threshold move to fit the data rather than the other way round.
- A shelf life supported answer of yes, marginal with no challenge test raised where the design calls for one, which leaves a borderline conclusion standing without the confirmatory test it was designed to trigger.
- An approved shelf life recorded with no restudy trigger defined, which means the next recipe, process or supplier change has nothing forcing the study to be revisited.
Global
Shelf Life Study Record requirements by country
Shelf life sits at the junction of food safety science and date-marking law, and the instrument that actually gets checked at audit or in an outbreak investigation depends on where the product is sold.
Regulation (EU) No 1169/2011 on food information to consumers
Sets the legal requirement to carry a use-by or best-before date, which this study is the technical justification for.
A use-by date under this regulation is a safety claim, not a quality one, so a shelf life study record supporting it needs the microbiological criteria and failure definition to be unambiguous, not just the sensory outcome.
Food Information Regulations 2014
Applies the EU date-marking framework in UK law and is the instrument a UK enforcement officer or auditor will ask the study to justify.
The approved shelf life and restudy trigger fields in this record are what a UK site produces when asked to demonstrate the use-by or best-before date on pack is substantiated.
FDA Food Code and product-category guidance (no single federal date-marking rule)
There is no single federal shelf-life dating requirement; obligations vary by product category and state, so the study itself, not a fixed clause, is what a US site relies on if challenged.
A US-facing site cannot point to one instrument the way a UK or EU site can, which makes this record's own documented worst-case batch, test-beyond-life and criteria-before-testing fields the primary evidence available.
How to complete it
How to complete a shelf life study record, step by step
Filling in every field does not make a shelf life study defensible on its own. Four judgement calls decide whether the conclusion holds up when the product is challenged.
Three batches from different production days meets the minimum count, but if none of them sit at the edge of the specification, such as highest permitted moisture or lowest permitted preservative, the study has still only characterised a typical batch. Worst-case inclusion is a separate judgement from batch count.
Testing beyond the proposed shelf life is what turns a survival date into a margin. A study that stops at the label date can support the date today and say nothing about how much buffer exists if storage conditions are slightly worse than assumed.
Criteria agreed before testing starts protect the conclusion from being shaped by the results. Criteria set or adjusted after results are in hand, even with good intentions, weakens the study's evidential value regardless of how the final numbers look.
A restudy trigger that names recipe, process, packaging and supplier change in the abstract is easy to write and easy to miss in practice. Whether it is tied to an actual change-control step elsewhere in the business, rather than left to memory, decides if the study gets revisited when it should.
What auditors find
Most common shelf life study record findings
These are the patterns that turn up most often when a shelf life study record is reviewed after the fact, rather than at the point the study was designed.
| Finding | Clause | What fixes it |
|---|---|---|
| Batches studied meets the minimum of three but worst case batch included is marked uncertain | BRCGS cl.5.1 | Require a documented specification check for at least one studied batch before worst-case inclusion can be marked yes. |
| Test beyond proposed life marked to the date only, with shelf life supported still marked yes with margin | BRCGS cl.5.1 | Block a with-margin conclusion unless testing extended past the proposed shelf life date. |
| Criteria agreed before testing marked after, with all criteria met marked yes | BRCGS cl.5.1 | Flag any study where criteria were agreed after testing for technical review before the conclusion can be approved. |
| Shelf life supported marked yes, marginal with challenge test required marked no | BRCGS cl.5.1 | Require a documented rationale whenever a marginal conclusion is not routed to a challenge test. |
| Approved shelf life recorded with restudy trigger defined marked no | BRCGS cl.5.1 | Make restudy trigger mandatory before a shelf life can be marked approved, tied to the specific change types that apply to the product. |
| Storage temperature controlled and logged marked controlled not logged, with all criteria met marked yes | BRCGS cl.5.1 | Require a temperature log reference before results collected under that storage condition can be accepted into the conclusion. |
Case in point
Case in point: the study that stopped at the label date
A chilled dairy line extended the shelf life on a cultured milk product by five days after a study that tested three batches to exactly the new proposed date, all of which passed. The study purpose was recorded as shelf life extension and the conclusion was shelf life supported, yes with margin, despite no test point existing beyond the new date to justify the word margin.
A customer complaint just inside the new date range prompted a review, which found the original study batch had in fact failed sensory criteria two days past that same date when retested. The extension was pulled back to the original life while a proper study, with test points beyond the proposed date and a worst-case batch, was run again. The gap was not the science; it was a record that let margin be claimed without a single data point supporting it.

From a document you fill in to a programme that runs itself
The form is the easy part. Choosing a genuine worst-case batch, holding criteria fixed before testing starts, and making sure a future change actually fires the restudy trigger is the work that actually slips.
Holds the shelf life study record against the product register, checks worst-case batch and criteria-before-testing answers before a conclusion is approved, and keeps the challenge test link live where the study calls for one.
Tracks the storage temperature logging behind each test point, so a study's controlled-not-logged answer gets flagged before it quietly weakens the conclusion.
Watches recipe, process, packaging and supplier changes against each product's restudy trigger, so an approved shelf life doesn't outlive the change that should have reopened it.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.

Shelf Life Study Record definitions and key terms
- Shelf life study
- A structured investigation of how a product changes over time under defined storage conditions, used to establish or extend the date on pack.
- Worst-case batch
- A batch produced at or near the edge of the product specification most likely to shorten shelf life, included specifically to test the limits of normal variation.
- Challenge test
- A deliberate inoculation study confirming that a product's formulation or process controls a specific organism of concern across its stated life.
- Restudy trigger
- A defined set of changes, such as recipe, process, packaging or supplier, that automatically invalidate an existing shelf life study and require it to be repeated.
- Abuse conditions
- Storage or handling conditions outside the intended regime, such as a temperature excursion, included in a study to test resilience beyond normal use.
FAQ
Frequently asked questions about shelf life study record
What is the shelf life study record template based on?+
It is built against BRCGS cl.5.1, which requires shelf life to be established through valid, product-appropriate studies rather than assumption. Date-marking obligations that sit alongside it are set by national or regional food information law.
What sections does the shelf life study record contain?+
There are six sections: header, design, criteria, results, conclusion and result. Together they hold 55 fields, 41 of which are required, with the results section repeating for each test point.
How many shelf life study records should we have?+
This is a singleton. One record per workspace, set up once and maintained, with new studies, extensions and periodic revalidations all logged against it as separate entries.
Which programme does the shelf life study record belong to?+
It is part of Labelling and Packaging, described as the leading cause of recalls caught by a two person check at every changeover.
How is a shelf life study record scored?+
Scoring runs on studies complete, where high is good. Testing beyond the proposed life scores higher than testing to the date only, and criteria agreed before testing scores higher than criteria agreed after.
Can the shelf life study record template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to the product register and micro results come with it. Most sites install it as it is, run one full study cycle, then adjust the test point schedule to match their product range.
