Restaurants and eateries will soon start metering carbon dioxide levels at sites, a new protocol says.

The state Department of Public Health said the measure was decided by a scientific committee in order to protect consumers from Covid-19.

State Commission to Protect against Sanitary Risks Director Erwin Areizaga said all restaurants will be mandated to include such items in their facilities to have proper ventilation.

Carbon dioxide levels must not be above 1,000 parts per million.

Restaurants must also include a list of customers visiting their facilities to follow up contagion chains.

The agency decided to suspend having shoe sanitizing features in the entrance of restaurants and spraying customers with sanitizer. However, all customers and employees must still use face masks, having their temperature taken, and usage of antibacterial gel.
