Scientific assessment

Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.

Certainty of evidence: moderate – Further research may still affect the assessment.

1. What was claimed?

Salmon is always farmed and should not be eaten.

2. What is demonstrably correct?

Most salmon sold in Egypt and Europe is farmed Atlantic salmon (common knowledge; no market-share figure was verified in this review).

3. What is wrong or exaggerated?

Not all salmon is farmed; wild Pacific salmon is sold. More importantly, the conclusion 'should not be eaten' is not supported: farmed Atlantic salmon had lower dioxins, PCBs and mercury than wild Atlantic salmon and gave about 3.2 g EPA+DHA per 200 g portion (I-FSH-02). Sea bass (قاروس) and sea bream (دنيس), which he recommends, are also widely farmed - he says so himself in a later video ('الدنيس معظمه مزارع').

4. What remains unclear?

The share of wild versus farmed salmon on the Egyptian market was not verified; contaminant data come from Norwegian monitoring (I-FSH-02, A-FSH-21).

5. Which studies support it?

Partly: most salmon sold in Europe and Egypt is farmed Atlantic salmon (common knowledge; no market-share figure verified). No study supports that farmed salmon should not be eaten.

6. Which studies contradict it?

I-FSH-02, A-FSH-21, I-FSH-01.

7. What applies to Germany and Europe?

Farmed salmon in German retail is monitored; no basis for avoiding it.

8. What is known about Egypt?

Imported salmon; not studied.

9. What practical conclusion is appropriate?

Salmon, farmed or wild, is a good omega-3 source.

Assessment details

Rationale for certainty of evidence

Wild salmon exists (e.g. wild Pacific salmon in A-FSH-01/A-FSH-07). Current contaminant data for farmed Atlantic salmon are below EU maximum levels and its omega-3 content is high (I-FSH-02). Also internally inconsistent: in a later video he says sea bream (دنيس) is mostly farmed too.

In plain language

Dr Elawady says that all salmon is farmed and should not be eaten. Wild salmon does exist, even if most salmon in shops is farmed. Recent Norwegian measurements found that farmed salmon has fewer pollutants than wild Atlantic salmon and gives plenty of omega-3. The fish he recommends instead, such as sea bream, are also often farmed, as he himself says in another video.

  • Wild vs farmed Atlantic salmon (Norway 2017)

    Measurement / residue studyindependent cross-checkabstract only checked★ key study

    Wild salmon had more dioxins, PCBs and mercury than farmed salmon; both were good omega-3 sources.

    Does the study support the specific claim? No · Methodological quality: moderate · Certainty of evidence: see overall assessment of the claim

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Compare same species.

    How was the study done?

    Chemical analysis.

    How many people, animals or samples were studied?

    Wild and farmed Atlantic salmon.

    What was actually found?

    Farmed lower in most contaminants.

    How large was the observed effect?

    3.2 g vs 2.8 g EPA+DHA per 200 g.

    What do the results mean in everyday life?

    Farmed salmon is not more polluted.

    What are the study's limitations?

    Details not in abstract.

    What does it say about Elawady's specific claim?

    Contradicts 'farmed is more polluted'.

    Do the results apply to Germany and Europe?

    High.

    What can explicitly not be concluded from this study?

    Other farmed species.

  • Pollutants in Norwegian farmed salmon 1999-2011

    Measurement / residue studycited by the Tayebat archivefull text checked★ key study

    Pollutant levels fell from 1999 to 2011 and no sample exceeded EU limits; the authors calculated up to 1.3 kg per week to reach the safety limit then in force, which EFSA has since made much stricter.

    Does the study support the specific claim? No · Methodological quality: high · Certainty of evidence: see overall assessment of the claim

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Track contaminants.

    How was the study done?

    Official surveillance.

    How many people, animals or samples were studied?

    >2300 samples (>10,000 fish), 1999-2011.

    What was actually found?

    Mercury, arsenic, dioxins, dioxin-like PCBs and DDT decreased; no EU limit exceeded; tolerable weekly amount rose from 370 g (1999) to >1.3 kg (2011).

    How large was the observed effect?

    1.3 kg/week to TWI (2011).

    What do the results mean in everyday life?

    Farmed salmon got cleaner.

    What are the study's limitations?

    Uses the old (2001) dioxin safety limit, 7 times less strict than EFSA's 2018 limit; other foods not counted; data end in 2011.

    What does it say about Elawady's specific claim?

    Contradicts claim.

    Do the results apply to Germany and Europe?

    High.

    What can explicitly not be concluded from this study?

    Levels after 2011, or safe amounts under the current (2018) EFSA dioxin limit.

  • Omega-3 in Scottish farmed salmon 2006-2015

    Sprague M et al.. Sci Rep 2016 · PMID 26899924 · DOI 10.1038/srep21892
    Measurement / residue studyindependent cross-checkfull text checked★ key study

    Omega-3 in farmed Scottish salmon roughly halved from 2006 to 2015 (2.74 to 1.36 g per 100 g), but it still had more omega-3 per 100 g than the wild salmon tested (0.76 g) and most other foods.

    How many people, animals or samples were studied?

    >3000 salmon.
