After getting chastised for failing to crack down on restaurants that break COVID-19 safety rules, Contra Costa County health inspectors this week visited 14 eateries, temporarily suspending one defiant diner’s permit, fining a repeat offender and issuing new warnings to others.

The restaurants were all suspected of violating COVID-19 health mandates enacted during the pandemic, such as requiring indoor diners to show proof that they’ve been vaccinated or had a recent negative COVID-19 test and requiring employees to wear masks inside.
