Mr Bolsonaro did not name the particular product – but said he had passed Mr Johnson’s request to his agriculture minister Tereza Cristina.
“He wants an emergency agreement with us to import some kind of food that is lacking in England,” the president said on his weekly webcast to supporters.
A No 10 spokesperson disputed Mr Bolsonaro’s account – saying it was not the UK delegation’s recollection of the conversation between the leaders, without giving further details.
The British embassy in Brazil also rejected Mr Bolsonaro’s claim, saying the president’s remarks did not reflect the leaders’ meeting in New York at the UN General Assembly earlier this week.
Mr Bolsonaro also said Mr Johnson also asked him to help increase Brazilian imports of whisky from the UK – but he added in his social media talk that this was up to private business in Brazil and not his government.
Shortages of fast-food chicken saw some Nando’s outlets close last month, with food sector chiefs pointing to the shortfall in production workers who returned home after Brexit and a drastic lack of lorry drivers able to come to the UK.
Food sector bosses have warned of further shortages of poultry and meat due to a sudden dearth of carbon dioxide used by the industry.
Mr Johnson and other government ministers have repeatedly brushed aside suggestions there could be shortages of traditional Christmas fare such as roast turkey – though suppliers have warned some families may have to do without this year.
The British Poultry Council (BPC) has warned the industry was heading into a “downward spiral towards supply chains seriously struggling”.
Ranjit Singh Boparan, the owner of Bernard Matthews and 2 Sisters Food Group, said earlier this week that the shortage of both CO2 and workers will affect the supply of turkeys for Christmas.
The Brazilian president’s office has not yet responded to requests for clarification on the particular food product he believed had been requested.
Brazil is the world’s third largest producer of poultry, including chicken and turkey, according to the Poultry World website.
