CSV separator is present in one of the value. How to ignore/handle such csv file?

I'm getting CSV file from external system. CSV is separated using ; but one of the record has value with ;

e.g:

name;age;address  
ab:20;12345  
s;m;30;12345  
xy;22;12345

How can I consider s;m as single value?
I'm using DataFrame of Joinery to read file and convert it to DataFrame to ease further operations:

Dataframe abc = DataFrame.readCsv(inputStream,";","", Boolean.TRUE);
