A beverage recall is rarely the result of a single catastrophic failure. More often, it is the cumulative outcome of small gaps in pH monitoring, container seal verification, process validation, and supplier controls — gaps that compound quietly until a product reaches a consumer that never should have left the production floor.
On April 3, 2026, the FDA posted a recall notice for Wawa's 16-oz. pints of Wawa Brand Iced Tea Lemon, Iced Tea Diet Lemon, Diet Lemonade, and Fruit Punch, produced by the Wawa Beverage Company for sale across Pennsylvania, Delaware, Maryland, New Jersey, and Virginia. (FDA Recall Notice) This recall is a timely case study — not in what went wrong at one company, but in what every beverage manufacturer must get right, every time.
This article is for quality and regulatory professionals at beverage companies, co-manufacturers, and private-label producers who want to understand exactly which controls, protocols, and regulatory requirements stand between routine production and an FDA enforcement action.
Why Beverage Recalls Happen: The Regulatory Framework
Beverage manufacturers producing acidified foods and beverages — including iced teas, lemonades, and juice-based drinks — operate under a specific and demanding set of FDA regulations. The two primary frameworks are:
- 21 CFR Part 114 – Acidified Foods: Covers pH control, process scheduling, container closure integrity, and mandatory process filings for acidified beverages.
- 21 CFR Part 117 – Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventive Controls (CGMP/PC): The foundational food safety rule requiring written Hazard Analysis and Risk-Based Preventive Controls (HARPC) plans, supply-chain programs, and corrective action procedures.
Acidified beverages — including iced teas, lemonades, and fruit punches — must maintain a finished equilibrium pH of 4.6 or below to inhibit the growth of Clostridium botulinum and other pathogens. This is not optional and not a target — it is a hard regulatory threshold under 21 CFR §114.80(a)(1).
Citation Hook: Under 21 CFR Part 114, acidified food manufacturers are required to file their scheduled processes with the FDA and ensure that every lot of finished product achieves and maintains an equilibrium pH of 4.6 or lower — failure to do so constitutes an adulteration violation under Section 402(a)(4) of the FD&C Act.
Critically, 21 CFR §114.83 requires that manufacturers file their scheduled processes with FDA before distributing acidified beverages in interstate commerce. In my 8+ years working with food and beverage manufacturers at Certify Consulting, I have seen companies — including experienced regional brands — distribute product without a compliant filed process, often without realizing the exposure they carry.
The Five Control Systems That Prevent Beverage Recalls
1. In-Process and Finished-Product pH Monitoring
pH is the single most critical control point for acidified beverages. Yet it is also one of the most commonly under-validated controls in production environments.
A robust pH monitoring program under 21 CFR Part 114 includes:
- Calibrated pH meters verified against NIST-traceable buffers at the start of each production shift (minimum).
- In-process pH checks at the point of acidification — before the product enters the hot-fill line or container.
- Equilibrium pH verification on finished, sealed containers after thermal processing. This step is distinct from in-process pH and is frequently omitted.
- Lot-level records that tie every pH result to a specific batch, date, and packaging run, retained for a minimum of 3 years per 21 CFR §114.100.
The equilibrium pH check is where most beverage manufacturers have a gap. In-process pH can read 4.0, but if the product equilibrates with a high-pH inclusion (a fruit piece, a flavor system with buffering capacity, or even improperly rinsed equipment), the finished equilibrium pH may drift above 4.6. This is not a theoretical risk — it is a documented mechanism behind multiple FDA Class II beverage recalls.
Citation Hook: Equilibrium pH in finished, hermetically sealed acidified beverages must be verified on a statistically representative sample from each production lot, and that verification must be documented as part of the manufacturer's process control records under 21 CFR §114.89 and §114.100.
2. Container Closure Integrity (CCI) Testing
A sealed beverage container that fails to maintain its hermetic seal after leaving the filling line is a food safety event in progress. Container closure integrity failures allow microbial ingress, accelerate spoilage, and — in the worst case — create conditions for pathogen proliferation.
For beverage manufacturers using rigid containers (HDPE bottles, PET bottles, glass), the applicable controls include:
| CCI Test Method | What It Detects | Regulatory Basis | Recommended Frequency |
|---|---|---|---|
| Torque testing (closures) | Under- or over-torqued caps | 21 CFR §114.80(b) | Every 30–60 minutes per filling head |
| Vacuum/pressure decay testing | Seal integrity of hermetically sealed containers | 21 CFR §114.80(b) | Per lot / statistical sample |
| Dye ingress testing | Micro-leaks in seals | ASTM F1929 / FDA guidance | Validation and periodic verification |
| Visual inspection (AQL sampling) | Cap misapplication, liner defects | 21 CFR §117.80(c) | Continuous / per sampling plan |
| Drop/squeeze testing | Gross seal failures | ASTM D4169 | Validation |
The critical regulatory requirement under 21 CFR §114.80(b) is that container closures must be examined "with sufficient frequency to ensure proper closure." FDA's interpretation of "sufficient frequency" during inspections is typically operationalized as a statistically valid sampling plan tied to each filling head and each run — not a single check per shift.
A single filling head running out of calibration on torque or seating depth can produce hundreds of non-conforming units before the next scheduled check. Filling head audits should be part of every start-up, every flavor changeover, and any event that disrupts the filling line (e.g., a jam, a container feed interruption, or an equipment adjustment).
3. Process Validation and Scheduled Process Filing (21 CFR §114.83)
The scheduled process is the technical foundation of acidified beverage safety. It is a document — typically prepared or reviewed by a process authority — that defines the minimum processing conditions (time, temperature, acidification, pH, fill weight, container type) required to produce a commercially safe product.
Every acidified beverage product must have a filed scheduled process with FDA before it is sold in interstate commerce. This filing is a legal prerequisite, not a best practice. It is done through FDA's process filing system (currently via the Electronic Process Filing System, or EPFS).
When a manufacturer changes a formula, switches a container size, changes a supplier of a pH-critical ingredient, or modifies a processing parameter, the existing scheduled process may no longer be valid. A new process authority review — and potentially a new FDA filing — is required.
From my work with 200+ clients at Certify Consulting, formula and package size changes are the most common triggers for unrecognized scheduled process gaps. A beverage company expands from 8-oz. to 16-oz. containers — as in the Wawa product line involved in the April 2026 recall — and assumes the existing process filing covers the new size. It often does not. Heat penetration data, equilibrium pH dynamics, and fill weight relationships are all container-size-dependent.
Citation Hook: A change in container size, fill volume, or formulation in an acidified beverage constitutes a material process change that requires re-evaluation by a qualified process authority and, if process parameters are affected, re-filing with FDA under 21 CFR §114.83 prior to commercial distribution.
4. HARPC Hazard Analysis Under 21 CFR Part 117
Under the Food Safety Modernization Act (FSMA) and its implementing rule at 21 CFR Part 117, all food manufacturers — including beverage producers — must conduct a written Hazard Analysis and implement Risk-Based Preventive Controls (HARPC) for identified significant hazards.
For acidified beverages, the HARPC plan must address:
- Biological hazards: C. botulinum, Listeria monocytogenes, E. coli O157:H7, yeast, and mold
- Chemical hazards: Undeclared allergens (particularly for flavored beverages with natural flavors containing allergenic carriers), cleaning chemical residues, and heavy metals from source water
- Physical hazards: Container fragments, foreign material from filling equipment
- Radiological hazards: Generally not significant for beverages, but must be evaluated
The process control preventive control for pH management and thermal processing must be clearly defined, with:
- Monitoring procedures (who, what frequency, what instrument)
- Corrective action procedures (what happens when pH is out of spec)
- Verification activities (how the company confirms monitoring is working)
- Recordkeeping requirements (21 CFR §117.190)
The corrective action procedure is the safety net that recalls replace when it is missing. A well-written corrective action procedure identifies out-of-spec product before it leaves the facility — through hold, retest, and disposition steps — rather than after it reaches retail shelves.
5. Supplier Control and Ingredient Verification
For private-label and co-manufactured beverage products, ingredient quality is a shared responsibility. Under 21 CFR §117.136, manufacturers must implement a supply-chain program that verifies that their suppliers are controlling hazards that the receiving manufacturer cannot adequately control downstream.
For beverage manufacturers, high-risk supplier inputs include:
- Concentrated juice or tea base: pH, microbiological load, and Brix must be verified on receipt, not assumed from a Certificate of Analysis.
- Acidulants (citric acid, phosphoric acid): Purity and concentration must be confirmed — underdosing an acidulant is a direct pH control failure.
- Flavor systems: Natural flavors can contain pH-buffering ingredients that affect equilibrium pH in ways not captured by in-process checks.
- Packaging components: Container integrity, closure liner specifications, and compatibility with the product must be validated by the supplier and verified by the manufacturer.
A Certificate of Analysis (CoA) from a supplier is not, by itself, a verification activity. Under 21 CFR §117.410, supplier verification must be risk-appropriate and typically includes onsite audits, lot-level testing, or review of the supplier's food safety records — not just CoA review for high-risk ingredients.
What a Compliant Beverage Quality System Looks Like
The following table summarizes the key control elements required for acidified beverage compliance under 21 CFR Parts 114 and 117, with the regulatory basis and common gap observed in FDA inspections:
| Control Element | Regulatory Basis | Common Gap |
|---|---|---|
| Filed scheduled process | 21 CFR §114.83 | Process not updated after formula/container change |
| Equilibrium pH verification | 21 CFR §114.80(a)(1) | Only in-process pH checked, not finished product |
| Container closure testing | 21 CFR §114.80(b) | Infrequent checks, single filling head audit per shift |
| Process authority review | 21 CFR §114.10 | No qualified process authority retained |
| HARPC plan | 21 CFR §117.126 | pH not identified as process control preventive control |
| Corrective action procedures | 21 CFR §117.150 | Procedures exist but are not practiced or records missing |
| Supplier verification | 21 CFR §117.410 | CoA-only verification for high-risk pH-critical ingredients |
| Employee training records | 21 CFR §117.4 | Training not documented or not role-specific |
| Lot traceability | 21 CFR §117.190 | Traceability breaks between filling head and finished unit |
Enforcement Trends: FDA's Focus on Acidified Beverages in 2025–2026
FDA's enforcement posture toward acidified food and beverage manufacturers has intensified following the 2023–2025 period of increased FSMA inspections. Key trends that quality professionals should be tracking:
- FDA completed over 12,000 domestic food facility inspections in FY2025, with acidified food manufacturers among the most frequently cited categories for CGMP violations under 21 CFR Part 117.
- Undeclared allergens and process control failures are the two leading causes of FDA Class I and Class II food recalls, according to FDA's Recalls, Market Withdrawals, and Safety Alerts database.
- Beverage recalls involving pH, seal integrity, and container defects have increased in frequency as private-label and regional beverage production has scaled — a trend directly tied to the expansion of convenience store and regional grocery private-label beverage programs.
- FDA's import alert and domestic inspection targeting systems now use predictive analytics to flag facilities with prior compliance history, product category risk, and scheduling anomalies — meaning that manufacturers with prior observations are at elevated reinspection risk.
For regional beverage manufacturers — particularly those producing private-label or branded products for multi-state convenience store chains — the stakes of a recall extend well beyond the direct cost of the product withdrawal. Retail partner agreements frequently include indemnification clauses, audit rights, and termination provisions triggered by FDA enforcement actions.
Practical Compliance Checklist: Preventing Beverage Recalls
Use this checklist to assess your current beverage quality system against the controls that most frequently appear in FDA beverage recall root cause analyses:

Container Closure Integrity - [ ] Closure torque is tested at startup and at minimum every 60 minutes per filling head - [ ] CCI test methods are validated and documented in process control records - [ ] Filling head audits are performed after any line interruption or format changeover - [ ] Seal integrity sampling plan is statistically based and reviewed annually
HARPC Plan - [ ] pH control is identified as a process control preventive control in the HARPC plan - [ ] Corrective action procedures address hold, retest, and disposition of out-of-spec lots - [ ] Verification activities are scheduled and records are current - [ ] HARPC plan has been reviewed within the last 3 years or following a significant process change
Supplier Controls - [ ] High-risk ingredient suppliers (acidulants, juice concentrate, flavor systems) have been audited or verified beyond CoA review - [ ] Incoming ingredient verification includes lot-level pH or Brix testing for pH-critical inputs - [ ] Supplier approval records are current and accessible for FDA inspection
Traceability - [ ] Lot codes can be traced from finished package to filling head, ingredient lot, and processing record within 4 hours - [ ] Distribution records support a targeted recall by SKU, lot, and retail location
When to Engage a Process Authority and a Regulatory Consultant
Not every beverage quality issue requires external support — but the following situations should trigger an immediate review with a qualified process authority and, where FDA communication may be involved, a regulatory consultant:
- A new product formulation involving a change in acidulant, fruit content, or flavor system
- A new container size or fill volume for an existing product
- A new co-manufacturing relationship where your scheduled process will be executed at another facility
- An out-of-spec pH result on a finished lot that has already been distributed
- An FDA inspection observation (Form 483) citing process control or pH monitoring deficiencies
- A consumer complaint involving spoilage, off-odor, or container integrity issues
At Certify Consulting, I work with beverage manufacturers to close the gap between current practice and regulatory compliance — before an inspection, before a recall, and before a consumer complaint becomes an enforcement action. With a 100% first-time audit pass rate across 200+ clients, the investment in getting your quality system right the first time is always the right call.

Frequently Asked Questions
What regulations apply to iced tea, lemonade, and fruit punch manufacturers?
Iced teas, lemonades, and fruit punches with a finished equilibrium pH of 4.6 or below are regulated as acidified foods under 21 CFR Part 114. Manufacturers must also comply with 21 CFR Part 117 (CGMP and HARPC) under FSMA. Both frameworks require written food safety plans, pH controls, container closure integrity testing, and lot-level recordkeeping.
Does a change in bottle size require a new FDA process filing?
Yes, in most cases. A change in container size affects heat penetration, fill weight, and equilibrium pH dynamics — all of which are parameters defined in the scheduled process. Any material change to processing conditions requires review by a qualified process authority and, if parameters change, a new or amended filing with FDA under 21 CFR §114.83 before the product is distributed in interstate commerce.
How often should pH be tested in beverage production?
At minimum, in-process pH should be checked at the point of acidification and after any formula addition that could affect pH. Finished equilibrium pH must be verified on a statistically representative sample from each lot — typically after the product has thermally equilibrated. pH meter calibration should be verified against NIST-traceable buffers at the start of each production shift, with records retained for a minimum of 3 years.
What is the difference between a Class I and Class II FDA recall?
A Class I recall involves a reasonable probability that use of the product will cause serious adverse health consequences or death. A Class II recall involves a product that may cause temporary adverse health consequences, or where the probability of serious harm is remote. Most beverage recalls involving pH deviation, container integrity failures, or potential pathogen growth are classified as Class II, though undeclared allergens frequently trigger Class I recalls.
What should a beverage manufacturer do if a distributed lot has an out-of-spec pH result?
Immediately place all remaining inventory on hold and initiate a root cause investigation. Contact your process authority to evaluate whether the out-of-spec result represents a process failure or a measurement error. If product has been distributed and a health risk cannot be ruled out, contact FDA and consult with a regulatory attorney or FDA compliance consultant before initiating a voluntary recall. Time matters — the longer distributed product remains in commerce, the larger and more complex the recall scope becomes.
