The Centers for Disease Control recommendations against gatherings have changed rapidly in just five days. On Thursday it was nothing larger than 500. On Sunday it was nothing larger than 50. By Monday, President Donald Trump changed the recommendation to 10.

The Texas Restaurant Association says the state's 55,000 restaurants must be allowed to continue operations during this crisis.

“Keeping restaurants open to provide food via delivery or take-out and pick-up, enhanced with safe, zero-contact curbside pick-up, is vital to the support of Texas’ communities," said TRA president Emily Williams Knight.

Cassanova says those options are all considered safe.

"It's not the food itself is the issue or the problem. It's the proximity to other individuals," he said. "Food itself should not pose a risk to individuals. Or the preparation of food," he added.
