Kellogg joined a host of other multinationals in exiting Venezuela and later confirmed President Nicolas Maduro's leftist government had taken over its manufacturing plant.
On Wednesday, Aragua state Governor Marco Torres slammed Kellogg and guaranteed food production would continue.
"With no notification, this U.S.-based multinational decided to close its doors, leaving 570 workers hanging," said Torres at the plant, in Maracay.
"Yet, we're here - in less than 24 hours."
Millions in Venezuela suffer food and medicine shortages amid hyperinflation. Maduro blames Venezuela's crisis on an "economic war" that he says is being waged by Washington, greedy businessmen and coup-mongers.
He is expected to win Sunday's presidential election, described by the opposition as a sham.
Clorox, Kimberly-Clark, General Mills, General Motors and Harvest Natural Resources are the most recent big names to pull out of Venezuela in the face of economic conditions.
Opposition critics scoffed that the government would quickly plunder the Kellogg plant and ruin its business.
