Vending Machine Allergen Risk Facilities Management Blind Spot
What You Really Need to Know
The Hook The Snickers Bar That Caused Anaphylaxis
Scene: Corporate headquarters, Dublin. 500 employees across 8 floors. 20 vending machines (snacks, drinks, sandwiches). Facility Manager outsources restocking to VendCo Ltd.
Tuesday, 2 PM: Emma, marketing coordinator, buys a “Fruit & Nut Cereal Bar” from Floor 3 vending machine (coil D7).
Tuesday, 6 PM: Emma in hospital anaphylactic shock (severe nut allergy). She has an EpiPen, survives, but misses 3 weeks of work.
The investigation:
- Emma’s “Fruit & Nut” bar was nut-free (ingredients: oats, dried fruit, honey)
- But: Coil D7 sits directly above Coil D8 (Snickers bars—contains peanuts)
- D8 was overstocked (48 Snickers instead of max 40) → top row pressed against D7’s product
- Peanut dust/residue transferred from Snickers wrapper to Emma’s bar wrapper
- Cross-contact contamination
The liability cascade:
|
Party |
Claim |
Outcome |
|---|---|---|
|
Emma |
Sue employer (medical costs + lost wages + distress) |
✅ Employer settles (provided unsafe facility) |
|
Employer |
Sue VendCo (“Your restocking caused contamination”) |
⚖️ Partial recovery (long legal battle) |
|
VendCo |
Sue Facility Manager (“You didn’t specify cross-contact protocols”) |
❌ Fails (restocking contract silent on allergen protocols) |
|
Facility Manager |
Disciplined internally |
⚠️ Reprimand (failed duty of care oversight) |
The trap: Facility Managers think “vending is the contractor’s problem.” But under Section 8, Safety, Health & Welfare at Work Act 2005 + EU Regulation 1169/2011, if you provide the facility (vending machines), you’re responsible for ensuring it’s allergen-safe even when outsourced.
The Legal Reality Vending Machines = Food Business
Who’s Liable?
FSAI Guidance: “Vending Machines”:
“Vending machine operators are considered a food business and must comply with Regulation 852/2004/EC on food hygiene.”
Translation: The moment you install a vending machine on-site (even if outsourced), you’re involved in a food business operation.
Liability hierarchy:
|
Party |
Legal Obligation |
Liability |
|---|---|---|
|
Vending Contractor (VendCo) |
EU Reg 852/2004: Food safety management, allergen protocols |
Primary (direct control of restocking) |
|
Facility Manager / Building Owner |
Section 8, Safety Act 2005: Provide safe workplace, oversee contractors |
Secondary (duty to ensure contractor compliance) |
|
Employer (if separate) |
Section 8: Duty of care to employees |
Joint (with FM if facility provided) |
Critical finding: Even if you outsource, you retain oversight duty. If the contractor fails, you share liability.

The FSAI Allergen Exemption Loophole
The Confusing Rule
FSAI Guidance Note 28 (updated 2025):
“Declaration of food allergens is not required for the sale of foods in automatic vending machines.”
What this means:
- Prepacked foods IN vending machines don’t need separate allergen labels ON the machine
- Because: The individual product packaging already has allergen labels (per EU 1169/2011)
What it does NOT mean:
- Vending operators are exempt from preventing cross-contact
- Facility Managers can ignore allergen contamination risks
The trap: FMs read “no allergen declaration required” and assume “allergen safety isn’t our problem.”
Reality: You still must ensure the vending setup doesn’t cause cross-contact.

Three Hidden Hazards in Vending “Valley”
Hazard #1: Coil Proximity (The “Snickers Above Fruit Bar” Problem)
The setup:
- Vending machines have multiple coils (spiral dispensers)
- Products stacked vertically in each coil
- Coils sit side-by-side and above/below each other (e.g., D7 next to D8, D8 above E7)
The risk:
- D8 = Snickers (contains peanuts)
- D7 = “Nut-Free” granola bar
- Restocking staff overfill D8 (48 bars instead of 40) → top bars press against D7’s products
- Peanut dust/oil from Snickers wrappers transfers to D7 wrappers
- Customer with nut allergy buys D7 bar → cross-contact contamination
Real-world incident (UK 2023, applicable to Ireland):
A university vending machine had “May Contain Nuts” warnings on 8 products. Investigation found 12 out of 30 products had nut residue due to coil proximity not listed on packaging.
Hazard #2: Restocking Cross-Contamination
The problem:
- Restocking staff handle multiple products in one visit:
- Restock Coil A (Peanut M&Ms)
- Move to Coil B (Dairy-free chocolate)
- Move to Coil C (Gluten-free crisps)
- No handwashing between coils
- No glove changes
- Allergen residue on gloves transfers to “allergen-free” products
The science:
- Peanut protein (Ara h 1) survives on surfaces for 180 days (Journal of Allergy and Clinical Immunology, 2019)
- Dry hands transfer 0.5–2 mg protein per touch (enough to trigger severe reaction)
Typical scenario:
- Staff touches peanut butter cookie wrapper
- Touches dairy-free bar wrapper 30 seconds later
- Customer with dairy allergy buys “dairy-free” bar
- Peanut protein present (not dairy, but still dangerous if dual allergy)
Hazard #3: Machine Hygiene (Mold, Expired Products)
The problem:
- Vending machines rarely deep-cleaned (quarterly at best, often longer)
- Spilled crumbs accumulate in coils (chocolate, nuts, grains)
- Mold grows in warm, humid machines (especially sandwich/fresh food units)
- Expired products sit for weeks (staff don’t systematically check dates)
The risks:
- Mold spores cross-contaminate fresh products
- Expired sandwiches (listeria risk) sit next to fresh items
- Allergen residue buildup in coils (can’t be removed by restocking staff alone)
FSAI requirement (Reg 852/2004, Chapter III):
“Vending machines must be sited, designed, and constructed to avoid contamination risk.” + “Machines must be cleaned regularly.”
Reality: Most contracts specify “restock as needed” no cleaning protocol.
The Contractor Blind Spot When FM Contracts Fail
Typical Vending Contract Language
What contracts say:
- “Contractor will restock vending machines weekly.”
- “Contractor responsible for product quality.”
- “Contractor indemnifies client against food safety claims.”
What contracts DON’T say:
- ✖️ Allergen cross-contact protocols (coil spacing, handling procedures)
- ✖️ Staff training requirements (HACCP Level 1, allergen awareness)
- ✖️ Cleaning frequency (coil interiors, not just external wipe-down)
- ✖️ Incident reporting (if customer reports reaction, who investigates?)
The legal trap:
“Indemnification” clauses don’t protect you from employee lawsuits. If your employee sues (Emma’s case), you settle first, then try to recover from contractor (expensive, time-consuming, partial recovery at best).
Case Study UK University (Applicable to Ireland)
Background: 8,000-student university, 45 vending machines across campus. Outsourced to VendCo.
March 2023: Student with severe nut allergy buys “Nut-Free Granola Bar” (Coil F12). Within minutes, anaphylaxis (hospitalized 2 days).
Investigation:
- Coil F12 sat directly adjacent to Coil F13 (Peanut Butter Cookies)
- F13 overstocked by 12 units → products leaning against F12 divider
- Peanut residue found on 3 out of 8 “Nut-Free” bars in F12
Liability:
- University settled with student
- University sued VendCo for partial recovery
- Net result: Significant financial loss + legal fees + reputational damage
Post-incident changes:
- Contract rewrite: Added “allergen cross-contact protocol” (coils with nuts must have 2-coil buffer from “nut-free” coils)
- VendCo staff training: HACCP Level 1 + allergen awareness (mandatory for all restockers)
- Quarterly audits: University FM checks coil spacing, expiry dates
Lesson: Prevention measures would have avoided the entire incident.
The Solution: 4-Part FM Vending Protocol
Protocol #1: Allergen-Safe Coil Layout
The rule: “Buffer zones” between allergen-heavy and allergen-free products.
Example layout (snack machine, 6 columns × 10 rows):
|
Column |
Products |
Buffer |
|---|---|---|
|
A |
Peanut M&Ms, Snickers, Reese’s (nut products) |
— |
|
B |
BUFFER (non-allergen: plain crisps, pretzels) |
✅ |
|
C |
Dairy-free chocolate, vegan bars |
— |
|
D |
BUFFER (water bottles, non-food items) |
✅ |
|
E |
Gluten-free crisps, GF cookies |
— |
|
F |
Standard chocolate bars (dairy, no nuts) |
— |
Why it works:
- Physical separation prevents direct contact between allergen products
- Buffer products (non-allergen or non-food) act as protective barrier
- Simple to implement during regular restocking
Protocol #2: Restocking Hygiene Checklist
What VendCo staff must do:
✅ Step 1: Wear clean disposable gloves (change between allergen categories)
- After handling nuts → new gloves before handling dairy-free
- After handling dairy → new gloves before handling vegan
✅ Step 2: Check expiry dates (remove products within 7 days of expiry)
✅ Step 3: Avoid overstocking (max capacity per coil = typically 40 units)
✅ Step 4: Wipe coil dividers with allergen-safe cleaner (quarterly deep-clean by specialist)
✅ Step 5: Log restock date + products loaded (for traceability if incident occurs)
Enforcement: Include checklist in FM-VendCo contract with clear consequences for non-compliance.
Protocol #3: Quarterly Allergen Audit (FM Responsibility)
-
What Facility Manager checks (quarterly inspection):
✅ Coil spacing: Are nut products adjacent to nut-free? (Flag for buffer zone) ✅ Expiry dates: Spot-check 5 random products (remove if <7 days remaining) ✅ Machine hygiene: Visible mold, crumbs, or residue? (Schedule deep-clean) ✅ Contractor logs: Did VendCo document recent restocks? (Verify glove protocol followed)
Documentation: FM completes “Vending Safety Audit” form (meets Section 8 oversight duty, provides evidence for FSAI inspections).
Protocol #3: Quarterly Allergen Audit (FM Responsibility)
-
What VendCo staff must complete:
- HACCP Level 1 (online, certificate valid 2 years)
- Covers: Cross-contamination, temperature control, personal hygiene
- Specifically addresses handling multiple allergen categories
- Allergen Awareness Module (online, certificate included)
- Covers: 14 major allergens, cross-contact vs. cross-contamination, glove protocol
- Visual scenarios: “You just restocked Snickers. Can you touch the vegan bars next?” (Answer: No change gloves first)

Action Plan: 6 Weeks to Vending Safety
| Week | Task | Outcome |
|---|---|---|
| 1 | Audit all vending machines: Document coil layouts, check expiry dates, count machines | Baseline data (identify high-risk coil configurations) |
| 2 | Hire FM consultant: Review VendCo contract for allergen compliance gaps | Gap analysis report with specific recommendations |
| 3 | Rewrite contract: Add allergen protocols, training requirements, quarterly audits | Updated contract (legally enforceable safety standards) |
| 4 | Enroll VendCo staff in Acornstar HACCP L1 + Allergen Awareness | Certificates issued, compliance documented |
| 5 | Implement coil layout changes: Restock with buffer zones between allergen categories | Allergen-safe physical setup |
| 6 | Conduct first FM quarterly audit: Check compliance, document findings | Audit report for FSAI/HSA, establish baseline |
Result:
- Zero allergen cross-contact incidents (buffer zones + training)
- FSAI-compliant (contractor training documented, audits logged)
- Protected liability position (demonstrate due diligence)
- Staff confidence (employees trust vending machine safety)
