Remove a carriage return with sed

I have a large CSV file. One of the fields contains an error. This error appears as a new line in the file.

Since now i've been using notepad++ with this command to correct the problem :

\r";" => ";"

How can I do the same with sed ?

I've already tried

sed -i 's/\r";"/";"/g' /path/file.csv
sed -i 's/^";"/";"/g' /path/file.csv

no success, someone here know probably the right command
