Residents have expressed their disgust after a bug was filmed stuck to a burger from a Watford fast food outlet.

The customer shared a video of the insect online after they purchased a mini fillet burger from the KFC branch in High Street.

In a post on Facebook, they warned: “Please scan your food before eating, you may get more than you asked for."

Watch the video below:

In the video, a brown bug can be seen wiggling its legs as it is stuck between sesame seeds on the burger bun.

Another suggested however that the insect may have come from a pre-packaged salad bag and urged the customer to contact the branch manager to investigate it.

A KFC Spokesperson said: “We have strict hygiene and quality processes at our restaurants and we’ve not had any similar complaints at the KFC Watford – High Street branch.

"An investigation was carried out and confirmed that all necessary steps were taken that day.

"That being said, this wasn’t a great experience for the customer and we’d encourage them to get in touch with our care squad so that we can make things right.”
