Food manufacturing employs about 1.3 million people, according to a report by the Canadian Food Institute.
The number is up slightly from 1.2 million in 2016.
The jobs of food-processing, food-products, and packaging workers account for roughly a third of those jobs.
But that is far below the 12.5 million food-service jobs that have been added since 1980.
The industry has seen a spike in demand in recent years, as Americans eat more processed foods and as the world transitions away from high-fructose corn syrup and other sugar-sweetened beverages.
Some food companies are already laying off workers.
Kraft, a Kraft Foods subsidiary, said in February it was laying off 6,300 workers and closing restaurants in Wisconsin, Michigan and Ohio.
Kellogg Co., the world’s biggest cereal maker, said it was cutting 10,000 jobs.
And the food processing and packaging industry employs about 2.6 million people.
