Subway fans are sickened by clip showing how sandwich chain prepares its steak...with one viewer saying they'll 'never recover' from the grim sight

Subway - the sometimes beloved, sometimes controversial sandwich mega-chain - is facing heat on TikTok after a video was posted by someone who appears to be preparing the steak used to make sandwiches.

The account @howfoodismade posted a video last week showing the method used by workers to prepare subway meat for serving.

The clip has now amassed 8.8million views, and thousands of comments, many from shocked and disgusted users.

In the video, which is captioned 'How we make steak at subway,' an employee cuts open a transparent plastic bag of ground up meat and dumps its contents into a large bin, before proceeding to mix it around with his hand.

After the mushy-looking meat has been 'scrambled,' the employee portions it out by hand into smaller containers, each of which weigh in at 2.5 ounces.

The comments section of the viral video lit up with horrified comments, some even coming from former Subway workers.

'I worked at Subway and still have nightmares about prepping the teriyaki chicken,' said one person.

'I promise you making the tuna is worse,' wrote another former employee.

'Thank you for this information my fellow brother. Jersey Mikes it is,' wrote another viewer, advocating for a switch in loyalty to Subway's direct competitor.

The official Eggo Waffle account also weighed in to say: 'I will never recover from this.'

Others said it's essentially the fault of anyone going to Subway and ordering steak for expecting anything different than what's shown in the video.

Several years ago, Subway made headlines when a lawsuit questioned the quality and ingredients in its tuna - another divisive menu item.

At the time, the chain set up a website called SubwayTunaFacts.com, which is still active, to defend its tuna supply chain.

The suit, as the website points out, was dismissed last July.

The viral TikTok account has so far posted a limited number of videos revealing the behind-the-scenes workings of several enormous fast food chains, including McDonalds and Taco Bell.

With the rise of TikTok and other short-form video posting platforms, came the introduction of these sorts of behind-the-curtain clips that show (mostly American) consumers what they don't see about the preparation of their favorite on-the-go orders.
