The "Weak Flesh" probe into rotten and tampered meat products has wreaked havoc in the world's largest beef and chicken exporter
At least ten people have been arrested in Brazil over a rotten meal scandal in one of the country's largest companies.
Police are looking into claims that senior executives at food firm BRF paid bribes to conceal unhygienic conditions at meatpacking plants.
Search and seizure operations have been carried out across the country amid fears of a health risk.
"We detected the presence of salmonella and, we also found cases where results had been changed," said Alexandre Campos da Silva, inspection coordinator.
Government authorities, however, say there is no sanitary risk and say raids on affected premises were isolated incidents.
The inquiry, dubbed "Weak Flesh" has wreaked havoc on the sector and temporarily shut export markets to Brazil, the world's largest beef and chicken exporter. Last year, BRF reported a loss of some 360 million euros, its worst results ever.
The European Union is seeking details from the Brazilian government over risks to imports.
