The pub's owners, Whelen, said it was 'surprised and saddened' by speculation on social media.
It comes after claims were made that The Foundry didn't respond adequately after being informed that people who visited the pub had later tested positive for coronavirus.
The Foundry confirmed it received an email to say a customer had tested positive but insisted that it took all the right steps, including contacting Environmental Health. It also said that it was never contacted by NHS Test and Trace.
A spokesperson said: "Since allegations surrounding The Foundry pub were raised we have been in close contact with Public Health England and the Public Health Team at West Sussex County Council.
"They have confirmed that they have no evidence of The Foundry being linked to an outbreak of Covid-19 at this current time.
"We are overwhelmingly happy that our team and customers are safe.
"It is a truly awful virus and has devastated families and communities globally."
The Foundry, based in Southgate, Chichester, said that, following the comments on social media, customers contacted them asking if it was safe to go to the pub.
The pub claimed that the accusations have 'ultimately put local jobs at risk' and the owners were investigating where the claims on social media came from.
The spokesperson added: "However, we know that this has been created, driven and encouraged by the few not by the many.
"As a company we have invested hundreds of thousands of pounds in our business and created employment for local people.
"We will always continue to invest in our business and plans for hotel accommodation are being drawn up for both above the pub and on our land outside.
"New guidelines come into effect from Monday, and as always we will be ensuring we are creating a safe environment for our team and guests.
"We thank everyone who has reached out to support us and we hope to see you all again soon! Stay safe."
