Overview
Mudalal S. Toxins (Basel) 2024 · PMID 39591254 · DOI 10.3390/toxins16110499
In locally produced freekeh, more than 78% of samples exceeded EU limits for aflatoxin and ochratoxin in a screening test.
Does the study support the specific claim? Partly · Methodological quality: low
Plain-language summary
Study explained simply

2. Research question
How contaminated are locally produced freekeh products?
3. Study design and population
- Study design
- Measurement / residue study – Market survey of mycotoxins, impurities and microbial counts in freekeh
- Population
Local freekeh products
- Country
Palestine (An-Najah National University, Nablus; full text)
- Period
not stated in abstract
- Sample size
not stated in abstract
- Inclusion and exclusion criteria
Local freekeh products
4. Methods and endpoints
- Exposure / intervention
Freekeh products
- Comparator
EU maximum levels
- Endpoints
Aflatoxins, ochratoxin A, DON, T2/HT2; impurities; microbial counts
- Statistical methods
Descriptive
5. Actual results
- Results
Aflatoxins 3.17-3.33 ppb and ochratoxin 4.63-8.17 ppb; DON and T2/HT2 below detection; more than 78% of samples exceeded EU limits for aflatoxin and ochratoxin (4 and 5 ppb); some samples exceeded impurity limits (>2% straw/foreign grains).
- Absolute risks
not reported
- Authors' conclusion
Knowledge of quality, safety and labelling of freekeh is needed; contamination factors in the supply chain need study.
6. Strengths
- Regional (Levant) product data
7. Weaknesses
- Lateral-flow screening assay, not confirmatory LC-MS
- Small, local sample
- Single author
8. Risk of bias
- Orienting tool
- none applicable
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- high
- Rationale
Screening method and sampling limit reliability.
9. Assessment of the statistical interpretation
Exceedance of EU limits shows a production-quality issue, not a measured health effect.
10. Relevance to the specific claim
Limits the allowance: traditional roasting/drying in local production can bring mycotoxin contamination; applies to supply chain, not to freekeh as a whole grain.
11. Independent contrary findings
No health outcome data.
12. Transferability to Germany and Europe
Low (EU products are controlled).
13. Overall methodological judgement
Weak but regionally relevant contamination signal.
