F.D.A. inspectors normally examine operations at about 160 domestic manufacturing and food processing plants each week. Nearly one-third of them are considered to be at high risk of causing food-borne illnesses. Food-borne diseases in the United States send about 128,000 people to the hospital each year, and kill 3,000, according to the Centers for Disease Control and Prevention.
Domestic meat and poultry are still being inspected by staff at the Agriculture Department, but they are going without pay. The F.D.A. oversees about 80 percent of the nation’s food supply, as well as most overseas imports.
In a series of tweets, Dr. Gottlieb said he was taking steps to restore food safety surveillance inspections and to cover more of the high-risk sites as the shutdown continued. He said he hoped to bring back about 150 inspectors who had been furloughed during the shutdown, perhaps as early as next week.
