After a mother said in a Facebook post that she believed her daughter contracted a bacterial infection in the Gulf while vacationing in Destin, the Florida Department of Health said there are no public health concerns in Walton or Okaloosa County. Michelle Brown, from Indiana, wrote that her daughter contracted an infection called necrotizing fasciitis during a family vacation in Destin in early June. Returning to Indiana her daughter had surgery to remove the infection and developed septic shock, requiring a second surgery. She said she believes her daughter contracted the disease in Destin through a scrape on her big toe.
