ASDA is introducing Covid-19 marshals on the doors of its supermarkets to ensure customers wear masks properly and follow stricter Government guidelines.

The 1,000 Asda Safety Marshals are to be stationed at the front of every store and in the aisles of larger stores.

The company says staff will help shoppers with safety questions and will reiterate Government guidelines.

If customers are not wearing masks in store, they will be told they can buy a pack of disposable masks and pay for them as part of their shopping trip.

Extra hand sanitiser stations will be provided in the busiest parts of the stores and protective coatings will be applied to all basket and trolley handles.

Following the recent change in Government guidance, all Asda store staff in England, Wales and Scotland will now wear a face covering while at work unless they have a medical exemption, the supermarket added.

Anthony Hemmerdinger, chief operating officer said: “We know that safety remains a key priority for our customers and we will continue to do all we can to keep them and our colleagues safe in store, as we have since the start of the pandemic.

“These additional measures will make our stores an even safer place to shop and work during the coming months.”

The move comes after rival Morrisons said it had reinstated marshals on the doors of its 494 supermarkets.

Supermarkets were granted “essential” status during the lockdown in March, leading to long queues and strict social distancing, although over time the rules were relaxed and enforcement reduced.
