Fear of ingesting a contaminated substance led Britain's Emma Raducanu to turn down treatment for an insect bite ahead of the Australian Open which starts this weekend.

Emma Raducanu said she believes she was bitten by jumping ants as she prepares for the start of the Australian Open. Raducanu disclosed Friday that she suffered swelling to her hand and ankle as a result.

Raducanu, who faces No. 26 seed Ekaterina Alexandrova in the opening round, said in her pre-tournament news conference that she got “badly bitten” by ants or mosquitoes Thursday January 9. Despite suffering what she described as an allergic reaction, Raducanu did not administer an antiseptic spray provided to her by someone in attendance.

Emma Raducanu has revealed she refused to use antiseptic spray on insect bites at the Australian Open, fearing it could lead to a failed drug test. The British No 2's cautious approach comes after recent positive tests by other players,
