Scientific assessment
Potentially true – Some evidence points in favour of the statement, but it is not sufficient for a clear judgement.
Certainty of evidence: low – Further research is likely to change the assessment considerably.
1. What was claimed?
Foods contain residues of drugs and pesticides.
2. What is demonstrably correct?
EU 2023: 42% of national-programme samples contained quantifiable pesticide residues (I-RES-05); EU 2024: 43.1% of coordinated-programme samples had no measurable residues, i.e. most contained some (I-RES-06). Egyptian studies found residues more often: pesticides in 86% of Nile tilapia (I-FSH-07), in 55% of 591 food and herb samples (I-RES-104) and in 24-49% of onion samples per year (I-RES-103); antibiotic residues in 52-72% of retail chicken samples in one town (I-RES-08) and gentamicin in 21% of chicken samples in another governorate (I-RES-101).
3. What is wrong or exaggerated?
Detection is not the same as harmful exposure. EFSA concludes 'low risk to consumer health' (I-RES-05, I-RES-06), and combined exposure to pesticides acting on the nervous system stayed below the regulatory threshold (I-RES-105). Egyptian risk assessments also found low exposure: at most 2.27% of the acceptable daily intake for onions (I-RES-103) and hazard quotients below 1 (I-RES-104, I-FSH-07, I-RES-08). 'Fertilisers' and 'stimulants' are vague.
4. What remains unclear?
Combined (cocktail) effects of low-level residues; long-term effects in high-exposure settings.
5. Which studies support it?
I-FSH-07, I-RES-08, I-RES-101, I-RES-104; I-RES-05, I-RES-06 (detection rates).
6. Which studies contradict it?
I-RES-05, I-RES-06, I-RES-105 (low risk; cumulative exposure below threshold); I-RES-103 (Egypt: exposure far below ADI).
7. What applies to Germany and Europe?
EU MRL system (Reg. 396/2005, Reg. 37/2010) with annual monitoring; low non-compliance.
8. What is known about Egypt?
Higher detection and exceedance rates reported in several Egyptian studies; monitoring gaps noted by authors.
9. What practical conclusion is appropriate?
Residues are real; in the EU they are mostly within legal limits. Washing/peeling produce and buying from controlled sources reduces exposure.
Assessment details
- Rationale for certainty of evidence
Detection of residues is well documented; whether they cause disease at typical exposures is a different question (see C-RES-02). Rated “Potentially true” because the factual part (residues are present) is correct, while the word 'toxins' implies harm that is not shown at usual levels in the EU.
- Source quality
Elawady's general statement; no data cited.
- Regional transferability
Region-dependent: EU monitoring shows mostly compliant samples; Egyptian studies show more frequent exceedances.
- Regional scope of the claim
- not specified
- Last reviewed
- 26 October 2026 provisional
Scientific evidence in detail
Overinterpreted – A real finding exists, but the claim draws more from it than the data allow (e.g. association taken as cause, animal data applied to humans, small effect presented as large).
Research question: Do everyday foods (EU and Egypt) contain residues of pesticides and veterinary drugs, and at what exposure relative to toxicological thresholds?
Research question in detail (PECO)
- Population
- General consumers
- Intervention or exposure
- Residues of pesticides, antibiotics and other agrochemicals in food
- Comparison
- Toxicological reference values (ADI/ARfD) and legal limits

What does the overall evidence say?
Editorial assessment based on the studies above – not itself a study result.
Which position is better supported?
Residues are common in food (EU and even more in Egyptian local studies), but measured exposures are mostly far below toxicological thresholds; calling them 'explicit toxins' that harm daily is not supported.
Why some studies weigh more
Official EU monitoring and risk assessment (high quality) and the largest Egyptian dataset (I-RES-103) weigh more than small local studies; detection is separated from exposure.
Is a causal relationship established? Not established Presence is established; harm at typical exposures is not.
Remaining uncertainty
Cumulative effects beyond the assessed endpoints; banned substances detected in Egypt (chlorpyrifos, nitrofurans).
Justified conclusion
The factual part (residues are present) is correct; the implied toxicity at usual levels is overinterpreted.
Why do studies seem to disagree?
High detection rates (I-RES-104: 55%) vs low exposure (I-RES-103: max 2.27% ADI): detection and risk answer different questions.
Does this depend on the country?
- General biological effects
- Toxicology universal.
- Eating habits
- Washing and peeling reduce some residues; boiling reduced gentamicin by over 90% (I-RES-101).
- Origin of the food
- Imported products (EU border data) show higher exceedance than EU-origin food.
- Contaminants
- Banned substances (chlorpyrifos after 2022, nitrofurans, chloramphenicol) reported in Egyptian studies.
- National production conditions
- Egypt: many local studies, no public national monitoring report (the project's research files).
- Legal rules
- EU Reg. 396/2005 and 37/2010; Egypt NFSA Decisions 6/2021 and 13/2020.
- Actual monitoring data
- EU: annual EFSA reports; Egypt: local studies only.
A regional difference is supported by robust data.
Statistical re-check
- Worst-case dietary exposure vs ADI – Highest raw liver gentamicin 378.5 ng/g -> 3.2% of ADI per 100 g; 0.15% after boiling. recalculated

In plain language
Dr Elawady says our food contains toxins such as residues of antibiotics and pesticides. It is true that many foods contain tiny traces of pesticides or veterinary drugs. In the EU, most samples are within legal limits, and EFSA judges the risk to consumers as low. Egyptian studies have found such residues more often and sometimes above legal limits.

- 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.

Study explained simply
- What did the researchers want to find out?
Is intake of high- vs low-pesticide-residue fruits and vegetables associated with mortality?
- How was the study done?
Three prospective cohorts (NHS, NHSII, HPFS)
- How many people, animals or samples were studied?
160,880 participants; 27,026 deaths
- What was actually found?
>=4 servings/day of low-residue FV: 36% lower mortality (95% CI 32%-41%) vs <1 serving/day; high-residue FV: HR 0.93 (0.81-1.07). Similar pattern for CVD, cancer and respiratory deaths.
- How large was the observed effect?
>=4 servings/day of low-residue FV: 36% lower mortality (95% CI 32%-41%) vs <1 serving/day; high-residue FV: HR 0.93 (0.81-1.07). Similar pattern for CVD, cancer and respiratory deaths.
- What do the results mean in everyday life?
A hint that residues might reduce the benefit of produce; eating fruit and vegetables was not harmful.
- What are the study's limitations?
Exposure assigned at food level, not measured in individuals; Residual confounding; Not a direct comparison of residue levels
- What does it say about Elawady's specific claim?
Weak indirect support; does not show residues cause chronic disease.
- Do the results apply to Germany and Europe?
US residue levels; EU levels differ.
- What can explicitly not be concluded from this study?
Cannot separate residues from other differences between foods.
No study in this group is marked as key.
Regional context
Germany / EU
EU MRL system (Reg. 396/2005, Reg. 37/2010) with annual monitoring; low non-compliance.
Egypt
Higher detection and exceedance rates reported in several Egyptian studies; monitoring gaps noted by authors.
- Food-safety governance and official controls
- Pesticide residues in fruit and vegetables on the EU/German market (incl. imports from Egypt)
- Pesticide residues in produce sold on the Egyptian domestic market
- Antibiotic (veterinary drug) residues in poultry meat and eggs
- Antimicrobial use in food animals and antibiotic growth promoters
- Hormones in poultry, meat, milk and farmed fish
- Dioxins, PCBs and PFAS in eggs and other animal foods
- Aflatoxin M1 in milk and dairy products
- Aflatoxins in groundnuts (peanuts)
- Heavy metals in fish
- Farmed fish (aquaculture): drugs, water source and controls
- Import controls and the meaning of RASFF notifications for Egyptian products
