Following dodgy salami, ultimately experience sickness (7)
I believe the answer is:
malaise
'sickness' is the definition.
(I've seen this before)
'following dodgy salami ultimately experience' is the wordplay.
'following' means one lot of letters go next to another.
'dodgy' indicates an anagram (a dodgy or wrong order of the letters).
'ultimately' indicates one should take the final letters.
The last letter of 'experience' is 'e'.
'salami' is an anagram of 'malais'.
'malais' put next to 'e' is 'MALAISE'.
(Other definitions for malaise that I've seen before include "General feeling of discomfort" , "Disquiet" , "Uneasy feeling" , "depression" , "sickness" .)
