Hong Kong has joined China is suspending meat imports from Brazil.
They are the top two consumers of Brazilian meat and have suspended imports over allegations that companies have been selling unsafe produce for years.
The European Union has also said it will stop buying from companies implicated in the scandal.
The crisis was triggered by a huge federal police operation on Friday.
It found evidence that meat-packers had been selling rotten and substandard produce for several years.
Hong Kong's Centre for Food Safety said it had temporarily suspended the import of frozen and chilled meat and poultry "in view of the fact that the quality of the meat from Brazil is in question".
Hong Kong is the second largest importer of Brazilian meat
Brazil is the world's biggest red meat and poultry exporter and the meat industry plays an important part in the economy.
President Michel Temer held emergency meetings over the weekend and even invited foreign diplomats to a steak house on Sunday evening to try to reassure them.
"The Brazilian government reiterates its confidence in the quality of a national product that has won over consumers and obtained the approval of the most rigorous markets," said Mr Temer.
But the effort was in vain. China, the EU, South Korea, Hong Kong and Chile have now announced restrictions on Brazilian meat products.
Together they account for nearly one third of Brazilian meat exports in 2016, O Globo newspaper reported.
Criminal investigation
Friday's federal raids at meat-producing plants ended in the arrest of more than 30 people.

The government suspended more than 30 senior civil servants who should have spotted the unhygienic and illegal practices - they are being investigated for corruption.
Three packing plants have been closed and another 21 are being investigated.
Mr Temer said the plants under scrutiny represented a tiny proportion of Brazil's meat industry.
"Only 21 units out of 4,837 in Brazil subject to government inspection are facing allegations of irregularities. And only six of them have exported in the past 60 days," said Mr Temer at a meeting with foreign diplomats on Sunday.
Operation Weak Flesh was launched in the early hours of Friday in six Brazilian states after a two-year investigation.
Federal police carried out raids in 194 locations, deploying more than 1,000 officers.
