Joesley Batista, one of the brothers who control JBS, recorded a conversation with Temer in which the president appears to condone bribing a potential witness.
Temer also denied other allegations, a report in a national magazine claiming that the country's secret security service, known as Abin, spied on the judge in charge of the same corruption probe.

After meeting with Solberg, President Temer said in a statement that the environmental issue was one of the main topics discussed with Norwegian authorities.
Outside Solberg's office, about 40 people protested against Temer with banners featuring slogans such as "stop rainforest destruction". Now they have much more to consider.
Batista secretly recorded Temer in an allegedly compromising discussion and gave the recording to prosecutors in a plea bargain to secure leniency in his own corruption case.
Monday's charging document alleges Temer arranged to eventually receive a total of 38 million reais ($11.5 million) from JBS in the next nine months.More news: 5 killed in cable auto accident in Indian-controlled Kashmir

Temer's supporters say they have between 250 and 300 votes in the 513 seat lower house to block a trial.
Earlier Monday, Temer sought to show that his government was conducting business as usual, defiantly saying he wasn't going anywhere in his first comments since returning from a trip to Russian Federation and Norway last week. "Nothing will destroy us - not me and not our ministers".
If congressmen rally around Temer, Melo said, "then we must face the horrific fact that what we have is a political system entirely detached from society, and it will pay the price in next year's election".
His trip last week to Russian Federation and Norway ended up underscoring the president's problems and Brazil's diminished stature overseas thanks to a steady stream of corruption scandals the last three years.
Launched in March 2014, the investigation into billions of dollars in inflated construction contracts and kickbacks to politicians has landed dozens of the country's elite in jail.
Temer's latest approval ratings are just seven percent, lower than his deeply unpopular leftist predecessor Dilma Rousseff whom he replaced previous year after she was impeached by his center-right congressional allies for breaking budgetary rules.
The survey by the Datafolha polling institute shows just 7 percent of those questioned approved of his administration, down from 9 percent in April.
"I plead with the president to meditate over the opportunity of such a gesture of greatness", said Cardoso.
