Overview
Ezzat A et al.. J Chromatogr B Analyt Technol Biomed Life Sci 2026 · PMID 41678938 · DOI 10.1016/j.jchromb.2026.124960
55% of 591 samples had residues; calculated risks were below the level of concern.
Does the study support the specific claim? Partly · Methodological quality: moderate
Plain-language summary
Study explained simply
- What did the researchers want to find out?
How frequent are pesticide residues in selected Egyptian foods and herbs and what are the hazard quotients?
- How was the study done?
Method validation plus market survey with hazard quotients
- How many people, animals or samples were studied?
591 samples
- What was actually found?
325 of 591 samples (54.9%) contained residues; 38 compounds, most frequent chlorpyrifos, cypermethrin, profenofos; dried mint 63.1% and hibiscus 64.2%; up to eight pesticides in one sample. THQ: chlorpyrifos in rice 0.286, profenofos in dried mint 0.098; all below 1.
- How large was the observed effect?
325 of 591 samples (54.9%) contained residues; 38 compounds, most frequent chlorpyrifos, cypermethrin, profenofos; dried mint 63.1% and hibiscus 64.2%; up to eight pesticides in one sample. THQ: chlorpyrifos in rice 0.286, profenofos in dried mint 0.098; all below 1.
- What do the results mean in everyday life?
Residues are common in Egypt, including banned chlorpyrifos, but measured risks were below thresholds.
- What are the study's limitations?
Sampling not described in abstract; Chlorpyrifos detected despite national ban (from 2022, per jurisdiction data)
- What does it say about Elawady's specific claim?
Supports detection, not harm.
- Do the results apply to Germany and Europe?
Not EU data.
- What can explicitly not be concluded from this study?
Cumulative exposure not assessed.

15. Linked fact checks
- Everyday foods carry 'explicit toxins': residues of antibiotics, fertilisers, stimulants/growth promoters, chemicals and pesticide residues, which the body must deal with daily. – Studies with mixed or unclear results
- Pesticide, antibiotic and hormone residues in food are a main cause of chronic health problems (implied by his theory statement and recurring remarks such as 'you are poisoned: the amount of pesticides and hormones'). – Studies contradicting or limiting the claim
