Bars, cafes and restaurants are being written to this week by Middlesbrough Council about their legal and social duties.
Since the hospitality industry was allowed to re-open last month the local authority has seen incidents of best practice from businesses in the town.
However, there have also been concerns raised regarding a lack of social distancing in and around some cafes, restaurants, retail premises, pubs and bars - whether when queuing for a seat, seating placed too close together, over capacity or customers standing or moving around premises without keeping a safe distance from others who are not from their household.
The Council's Public Protection Service is also contacting and visiting businesses linked to cases to assess their health, safety and Covid19 measures - including the records of customers kept as part of the track and trace system.
In particular businesses are reminded:
- A risk assessment around Covid-19 must have been carried out under health and safety legislation.
- Table reservations should be used when possible.
- Queues must be managed with social distancing in place.
- Queues should not obstruct pathways.
- Customers' details must be taken for track and trace purposes, as well as arrival times and a record of where they were seated.
- Face coverings for staff are recommended.
Middlesbrough Mayor Andy Preston said: "The response to re-opening has generally been really good and some businesses are showing us some really clever and inventive ways of keeping people safe and stopping the spread of Covid-19.
"We want to say to everyone in bars, cafes and restaurants in a friendly, but absolutely firm way, that we can't afford to let discipline around safety and social distancing measures slip.
"Face coverings for staff are really important too, they can help stop the spread but also give everyone more confidence that they're in a safe environment.
"It's so important to follow the guidelines and it's the only way we can protect people but also good jobs, good businesses and the whole economy of the town."
