FSANZ 2012 — Total and inorganic arsenic in apple and pear juice (Australia and New Zealand)

Food Standards Australia New Zealand (FSANZ) conducted a targeted analytical survey in 2012 measuring total and inorganic arsenic in 100 fruit juice samples (96 apple juice, 4 pear juice) drawn from Australian and New Zealand retail and manufacturing supply. Apple juice samples were re-analysed retention samples from a parallel FSANZ–MPI cyanogenic-glycoside (HCN) survey collected April/May 2012; pear juice samples were purchased separately by FSANZ from Queensland retail stores. Of the 96 apple juice samples, 34 (35%) had total arsenic above the laboratory’s level of reporting (LOR) of 2.5 µg/kg, with the highest total arsenic at 16 µg/kg; of those 34, 20 had quantifiable inorganic arsenic concentrations ranging from 2.5 to 11.3 µg/kg and 14 had inorganic arsenic at “trace” level (between the LOD of 0.5 µg/kg and the LOR of 2.5 µg/kg). No total arsenic was detected in any of the 4 pear juice samples; consequently no pear juice was further analysed for inorganic arsenic. The survey concluded that arsenic concentrations in Australian and New Zealand apple juice were broadly comparable to those previously reported in the United States.

Key numbers

Total arsenic (apple juice, n=96). Range <LOD (0.5 µg/kg) to 16 µg/kg. Of the 96 apple juice samples, 16 (17%) were <LOD, 50 (52%) were “Trace” (between LOD and LOR), and 34 (35%) were >LOR (≥2.5 µg/kg). Detection rate (>LOR) was 27% for Australian-purchased samples and 44% for New Zealand-purchased samples (Table 2). The highest total arsenic was 13 µg/kg in an Australian-purchased sample and 16 µg/kg in a New Zealand-purchased sample.

Inorganic arsenic (apple juice, n=34 with total As >LOR). Of these 34 samples, 14 had inorganic arsenic at “Trace” level (0.5–2.5 µg/kg) and 20 had inorganic arsenic >LOR, ranging 2.5 to 11.3 µg/kg (AsIII + AsV combined). The highest individual sample inorganic arsenic was 11.3 µg/kg in a New Zealand-purchased sample (paired with total arsenic of 13.3 µg/kg); the sample with the highest total arsenic (15.7 µg/kg) had a lower inorganic arsenic of 10.3 µg/kg. Detection rate of quantifiable inorganic arsenic among the 34 was 54% for Australian-purchased samples and 62% for New Zealand-purchased samples.

Arsenic speciation. Inorganic arsenic was reported as the sum of AsIII and AsV. AsIII concentrations ranged from <LOD (0.5 µg/kg) only up to “Trace” level (no sample had quantifiable AsIII ≥LOR). AsV was the predominant inorganic species when iAs was quantifiable: of the 34 samples analysed for inorganic arsenic, 14 (41%) had AsV at “Trace” level only, and 20 (59%) had inorganic arsenic (AsIII + AsV combined) ≥LOR — with AsV the quantifiable component in those 20 samples since AsIII never exceeded “Trace”.

Mean and median (middle-bound scenario, all 96 samples). Mean total arsenic 1.5 µg/kg (Australia, n=48), 2.7 µg/kg (New Zealand, n=48), 2.1 µg/kg (combined). Median 0.25 µg/kg in each group.

Mean and median (middle-bound scenario, the 34 samples with total As >LOR, for which inorganic As was measured). Total arsenic mean 4.8 µg/kg (Australia, n=13), 5.3 µg/kg (New Zealand, n=21), 5.5 µg/kg (combined n=34); median 3.9, 4.0 and 4.0 µg/kg respectively (Table 3). Inorganic arsenic mean 2.5 µg/kg (Australia, n=13), 3.5 µg/kg (New Zealand, n=21), 3.1 µg/kg (combined n=34); median 2.5, 2.6 and 2.5 µg/kg respectively (Table 4).

Mean inorganic arsenic for the 20 samples with quantifiable inorganic arsenic. 4.5 µg/kg (Australia), 5.4 µg/kg (New Zealand), 5.1 µg/kg combined (Table 4 ≥LOR column).

Pear juice (n=4). All four pear juice samples had total arsenic <LOD (0.5 µg/kg). No inorganic arsenic analysis was performed because the inorganic-arsenic method was applied only to samples with total arsenic >LOR.

Three-bound treatment of non-detects. FSANZ reported all means and medians under three scenarios (Table 1): Lower bound assigns 0 to <LOD and the LOD (0.5 µg/kg) to “Trace”; Middle bound assigns ½ LOD (0.25 µg/kg) to <LOD and the midpoint between LOD and LOR (1.5 µg/kg) to “Trace”; Upper bound assigns LOD (0.5 µg/kg) to <LOD and LOR (2.5 µg/kg) to “Trace”. For inorganic arsenic the middle-bound and upper-bound “Trace” assignments are 1.5 µg/kg and 2.5 µg/kg, identical to total arsenic.

US comparison (cited in Discussion). USFDA (2011) reported total arsenic 1.3–36 µg/kg in US single-strength apple juice (mean 6.7 µg/kg); two of 87 US samples exceeded 11 µg/kg. The FSANZ range for samples >LOR was 2.5–15.7 µg/kg total arsenic. Inorganic arsenic in the US dataset ranged 2.8–9.8 µg/kg versus 2.5–11.3 µg/kg in this FSANZ survey. The proportion of total-As-detect samples that also had quantifiable inorganic arsenic was 77% in the US dataset versus 62% (20/34 with iAs >LOR; or 100% [34/34] if “Trace” iAs is counted as a detection) in this FSANZ survey.

Regulatory context cited by FSANZ. Australia and New Zealand had no maximum level (ML) in the Food Standards Code for total or inorganic arsenic in fruit juice at the time of the survey. The US FDA established a 2008 “level of concern” of 23 µg/kg for total arsenic in apple and pear juice and, in July 2013, proposed a 10 µg/kg action level for inorganic arsenic in apple juice (matching the US EPA drinking-water standard for arsenic). Against the FDA proposed 10 µg/kg inorganic arsenic action level, of the 34 apple juice samples with total arsenic >LOR, 2 had inorganic arsenic ≥10 µg/kg (10.3 and 11.3 µg/kg in New Zealand-purchased samples) and 32 were below the proposed threshold.

Methods (brief)

Sampling. FSANZ engaged Symbio Laboratories (Queensland) to analyse 96 frozen apple juice retention samples (~80 mL each) that had originally been collected in April/May 2012 by ESR New Zealand and Australian state/territory jurisdictions for a parallel HCN survey. After the HCN analyses were complete the apple juice retention samples were air-freighted from ESR New Zealand to Symbio. Forty-eight apple juice samples were sourced from Australian retailers (covering all eight Australian states/territories at nine geographical locations) and forty-eight from New Zealand retailers (primarily in Christchurch); twelve of the original 108 New Zealand samples were not freighted to Australia for unknown reasons. Four pear juice samples were purchased separately by FSANZ from retail stores in Queensland and added to the survey. The sample comprised juices made with local and/or imported ingredients, reconstituted and not-reconstituted, shelf-stable and refrigerated. Apple aroma (flavour) extracts collected from juice-concentrate production were excluded.

Sample preparation. Frozen apple juice samples were defrosted in a refrigerator, then agitated/mixed prior to analysis. Pear juice samples were stored as per label directions. All concentrates were reconstituted to ready-to-drink before analysis; all results are reported on a ready-to-drink basis (not a concentrate basis).

Total arsenic. NATA-accredited method. Sample aliquots were mixed with nitric acid and digested, then purified water added, filtered, and loaded for inductively coupled plasma mass spectrometry (ICP-MS) with a collision-cell device. LOD 0.5 µg/kg, LOR/LOQ 2.5 µg/kg (ready-to-drink basis). Detections between LOD and LOR were reported as “Trace”.

Inorganic arsenic. Symbio Alliance in-house method. Aliquots from the 34 samples with total arsenic >LOR were combined with a methanol/water extraction solvent, agitated with an ultrasonic probe, centrifuged, the supernatant filtered, and loaded for HPLC-ICP/MS with a collision-cell device. Inorganic arsenic was defined as the sum of AsIII (arsenite) and AsV (arsenate). LOD 0.5 µg/kg, LOR/LOQ 2.5 µg/kg. Detections between LOD and LOR were reported as “Trace”.

Reporting bounds. All means and medians were reported in three bounded scenarios per Table 1 (lower / middle / upper bound), corresponding to standard EFSA/WHO non-detect handling.

Implications

Certification. Inorganic arsenic in apple juice is the primary toxicological concern for children, who are frequent and high-quantity consumers of apple juice (2007 Australian children’s survey: 45% consumed apple juice on the survey day, mean 141 g/day, 328 g/day at the 90th percentile; 2002 New Zealand children’s survey: 19% consumed apple juice on the survey day, mean 168 g/day, 495 g/day at the 90th percentile). This survey predates FDA’s July 2013 proposed 10 µg/kg inorganic-arsenic action level but the FSANZ data support that threshold as achievable in the Australia/New Zealand market: 32 of 34 samples with detectable total arsenic were below 10 µg/kg inorganic arsenic, and only 2 of 96 apple juice samples (~2%) exceeded the proposed action level. Pear juice non-detects (0/4) are supportive but the sample is too small for inference about the broader pear juice supply.

Courses. This survey is a clean example of the distinction between total arsenic and inorganic arsenic in a juice matrix: 52% of apple juice samples had “Trace” total arsenic but no quantifiable iAs analysis was performed below the 2.5 µg/kg LOR for total arsenic; among samples with quantifiable total arsenic, organic-arsenic species accounted for a non-negligible fraction (combined mean total As 5.5 µg/kg vs combined mean iAs 3.1 µg/kg in the 34-sample subset, suggesting organic forms in roughly 40% of total-As mass on average). Demonstrates why total-arsenic measurements alone overstate the inorganic-arsenic toxicology-relevant exposure in apple juice. Also illustrates the three-bound non-detect treatment used by FSANZ/EFSA/WHO.

App. For the Australia/New Zealand apple juice market c. 2012: typical inorganic arsenic among samples with detectable total As ~2.5–3.5 µg/kg (middle bound), upper observed individual value 11.3 µg/kg, range for quantifiable iAs 2.5–11.3 µg/kg. Pear juice not commonly consumed as a beverage but used as canning liquid in canned fruit and fruit purees.

Verification notes

This page is a 2026-05-20 merge-enhance pass over the 2026-05-14 initial-ingest version. The PDF was re-read in two chunks (pages 1–8 narrative + Tables 1–4; pages 9–15 references + Attachment 1 sample-by-sample data). Defects corrected in the enhance pass:

• source_type: peer-reviewed → gov-report. This is a FSANZ government survey report, not peer-reviewed literature. Convention used by the other FSANZ/FDA/EFSA government-report sources in the corpus.
• raw_path: truncated filename ...pear j.pdf → ...pear juice.pdf. The actual PDF filename ends in “juice.pdf”.
• products: removed non-existent products/fruit-juice (the page does not exist; routing was relying on a broad-scope token mapping). Replaced with products/fruit-juice-not-canned per current taxonomy. Removed products/fresh-fruit — this paper measured juices, not fresh fruit, and the inclusion was an inherited legacy from the matrix-to-product map’s fall-back routing of pear-juice → fresh-fruit. Added products/fruit-juices-non-apple to capture the 4 pear juice samples (non-detects).
• Inorganic arsenic narrative: the 2026-05-14 version stated “14 of the 34 Australian-purchased samples with detectable total As had inorganic As below the LOR of 2.5 µg/kg”. This conflated two facts: (a) the 14-sample iAs-trace count is across ALL 34 (13 Australian + 21 New Zealand), not Australian only; and (b) “Trace” iAs means between LOD 0.5 and LOR 2.5 µg/kg (a detection between the two limits), not below LOR by way of non-detect. Corrected to: “14 had inorganic arsenic at ‘trace’ level (between the LOD of 0.5 µg/kg and the LOR of 2.5 µg/kg)” and a separate explicit statement of the 13 AU + 21 NZ split.
• FDA 10 µg/kg action level comparison: original phrasing “none of the 34 exceeded 11.3 µg/kg inorganic arsenic” was technically true (11.3 was the max) but uninformative for the policy question. Replaced with the more relevant statement: 2 of 34 samples (10.3 and 11.3 µg/kg, both NZ-purchased) were at or above the FDA proposed 10 µg/kg, and 32 were below.
• Detection-rate numbers added: the AU (27%) vs NZ (44%) total-As detection rates and the AU (54%) vs NZ (62%) iAs detection rates from Table 2 were added — these were not in the prior version.
• Bound table: Table 1 (the lower/middle/upper-bound assignment scheme) was made explicit so readers can interpret the LB/MB/UB means without re-fetching the source.
• AU vs NZ Tables 3 and 4 detail: the 2026-05-14 page reported only the combined and partial sub-group means. The enhanced version reports all three of AU / NZ / combined for both total and inorganic arsenic across the middle-bound and the ≥LOR-only columns, matching Tables 3 and 4.
• Wiki pages updated on ingest: removed the prior reference to regulations/fda-ctz-iAs-apple-juice-10ppb. That page does not exist in the regulations directory and per the skill stop conditions this session does not create new regulation pages. The FDA action-level context is captured in the body prose.
• ingredients/pear-juice: declared in this page’s frontmatter but the wiki ingredient page did not yet exist at the time of the 2026-05-14 ingest. A provisional ingredient scaffold is being created via tools/autonomy/create-provisional-ingredient-scaffold.mjs in this enhance pass so the routing audit is clean.

Sample-by-sample verification: the highest-iAs sample (11.3 µg/kg, paired with total arsenic 13.3 µg/kg) was identified by cross-walking Attachment 1’s sample-level table; sample 46 is the only NZ & Imported sample in the table with AsIII+AsV = 0.0113 mg/kg. The other ≥10 µg/kg iAs sample is sample 6 (NZ & Imported, total As 0.0157626 mg/kg, AsV 0.0103 mg/kg = iAs 10.3 µg/kg).

2026-05-20 subagent audit (Agent tool, fresh context) returned REVISE with 2 ⚠️ findings, 0 ❌:

• Finding 1 (Check 1 numerical fidelity): the “AsV was the predominant inorganic species when quantifiable: 41% of speciated samples had AsV at trace level and 59% had AsV ≥LOR” sentence conflated AsV ≥LOR with iAs (AsIII+AsV) ≥LOR. Source p.7 text “Fourteen (41%) samples had trace amounts of AsV and 20 (59%) of samples analysed for inorganic arsenic had concentrations greater than 2.5 µg/kg” attributes the 59% to total iAs ≥LOR, not to AsV ≥LOR specifically. Applied: revised the Arsenic speciation paragraph to attribute 59% to combined iAs ≥LOR with AsV the quantifiable component (since AsIII never exceeded trace).
• Finding 2 (Check 2 slug vocabulary): ingredients/pear-juice is not in the taxonomy snapshot. Already addressed in the ingest commit — provisional ingredient scaffold was created via tools/autonomy/create-provisional-ingredient-scaffold.mjs and committed alongside the source page; taxonomy snapshot will pick it up on the next refresh.
