The main access road to Brazil's Paranagua port, the country's second busiest for grain exports, remained blocked by political protesters on Tuesday, according to a statement from the port authority, hobbling shipping from one of the world's top food producers.
Blockades in the area were first reported Monday afternoon after similar demonstrations erupted throughout the country as supporters of outgoing Brazilian President Jair Bolsonaro protested against his narrow election loss to leftist Luiz Inacio Lula da Silva.
Truckers, one of Bolsonaro's key constituencies, benefited from policies to lower fuel prices and have previously disrupted the Brazilian economy by shutting highways in recent years.
