Does a Video Present a Harmful Worm in a Bell Pepper?

In August 2019, we obtained a number of inquiries from readers concerning the details surrounding a viral video clip that confirmed what seemed to be an extended, stringy worm of some variety transferring about inside a inexperienced bell pepper.

The video was re-posted by a number of Fb customers, lots of whom warned viewers concerning the worm, which a number of of them described as doubtlessly harmful, and a few recognized as “the simla mirch” worm. 

On Aug. 20, a Fb consumer from Brazil posted the video, garnering nearly 10 million views inside per week. Her caption warned (translated from Portuguese): “Watch out with peppers … this worm known as Simla Mirch … a brand new worm which lives in moist areas of the physique … It might trigger ache and in the end result in demise”:

Different extensively shared movies didn’t particularly declare the worm might inflict ache or kill people, however did advise viewers, in broader phrases, to “watch out.” Some movies recognized the worm as “Simla Mirch.”

The video was undoubtedly a curiosity, and it’s not shocking that the unappetizing spectacle of a worm transferring about inside a well-liked vegetable brought about it to be shared extensively on social media. Nevertheless, a few of the particular claims related to it have been inaccurate.

The worm

Based on consultants we consulted, the creature proven within the video may be very prone to be a mermithid nematode worm (a member of the Mermithidae household and the nematoda phylum). They’re parasitic to bugs and spiders, however they don’t parasitize people, and they aren’t dangerous to us. 

Ben Hanelt, a senior lecturer in biology on the College of New Mexico and an skilled in parasitic worms, instructed Snopes in an electronic mail: “That is very probably a mermithid nematode. These usually are not pathogenic to people; solely to bugs.”

John Janovy, emeritus professor of organic sciences on the College of Nebraska-Lincoln and an skilled in parasite ecology, instructed Snopes “There’s a likelihood” the worm proven within the video was a mermithid nematode. In that case, he instructed us, it “is of no hazard to people.” 

Matt Bolek, an affiliate professor of integrative biology at Oklahoma State College and an skilled in parasite ecology and evolution, wrote:

“So far as I can inform to me this appears to be like typical of a mermithid nematode. These are parasites of bugs and spiders and emerge from the arthropod host to hunt both soil or water to develop to a free residing grownup worm.  Not harmful to people they usually [humans] can’t change into contaminated with this parasite.”

Bolek stated it was attainable that the worm was a horsehair worm (of the Nematomorpha phylus), however this was unlikely as a result of juvenile horsehair worms die rapidly after leaving their hosts, and the adults are darker in coloration than the worm proven within the video, and don’t transfer in the identical method.

He instructed us that the horsehair worm additionally doesn’t infect people, and “there are actually no different nematodes which have that coloration, transfer that method or are that skinny which have been reported to contaminate people.” So whether or not the worm proven within the video was a mermithid nematode (which a number of consultants instructed us was probably), or one other variety, it was not dangerous to people.

That refutes the reasonably alarming declare made in probably the most widely-shared posting of the video, that the worm “could cause ache and in the end result in demise.”

The life cycle of parasitic nematodes just isn’t for the faint of coronary heart. The worm proven within the video probably entered the pepper whereas it was a parasite of an insect or spider that bored its method inside. That’s, the arthropod was probably carrying a juvenile mermithid nematode inside its physique, and when the worm reached maturity, it emerged from the arthropod, killing it, and changing into “free residing,” that’s, not a parasite of one other animal.

The video under exhibits three mermithid nematodes rising from their host, a mosquito. It’s not suited to queasy viewers:


The pepper

“Shimla mirch” (misspelled as “simla mirch” in some Fb posts) is solely a Hindi title for Capsicum annuum, a species of the pepper plant and a well-liked method of describing bell peppers in India and Pakistan. 

Some social media customers who posted the video mistakenly described the worm, and never the pepper, as “simla mirch,” apparently resulting from a misreading of earlier posts by customers in India and Pakistan, lots of whom wrote: 

“Watch out of shimla mirch. New sort of worm. Lower correctly, examine and cook dinner.”

To readers in India and Pakistan, it could have been clear that these posts have been warning viewers to be vigilant when utilizing bell peppers (shimla mirch) due to the presence of a “new sort of worm.” Nevertheless, some readers exterior these nations understood “shimla mirch” to be the title of the “new sort of worm” and shared the footage together with that vital inaccuracy.


The video that went viral in August 2019 is genuine and does certainly present a worm transferring about inside a inexperienced bell pepper. Nevertheless, in keeping with the consultants we consulted, it’s prone to be a mermithid nematode, which isn’t parasitic of people and doesn’t pose a risk to us, opposite to the warnings posted on social media together with the video. 

Moreover, the worm proven within the video just isn’t “new,” though August 2019 was probably the primary time that tens of millions of viewers had come throughout the mermithid nematode. Lastly, “shimla mirch” (misspelled as “simla mirch”) is a Hindi title for the bell pepper proven within the video and never the worm itself.
