Mosse-Brown earned the title after the death of Italian Emma Morano, who died earlier this week at 117 years, 137 days old.
Mosse-Brown has a simple secret to her longevity.
“Really and truly, when people ask what me eat and drink to live so long, I say to them that I eat everything, except pork and chicken, and I don’t drink rum and them things,” Mosse-Brown told the Jamaica Gleaner in a 2010 interview in honor of her 110th birthday.
Mosse-Brown was born in 1900 and still lives in the same house with family members. The home has been in their family for the past 200 years.
According to a biography posted by the Violet Mosse-Brown Foundation, started by her family, she was a sugarcane farmer for much of her life.
According to CNN, she is the last living subject of Queen Victoria from when many of the Caribbean islands were ruled by the British.
