Following good opinions, terrible getting this from 1 down? (4,9)

Ross

I believe the answer is:

food poisoning

'this from 1 down?' is the definition.
The definition suggests a singular noun which matches the answer.

'following good opinions terrible' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'terrible' is an anagram indicator.
'good'+'opinions'='goodopinions'
'goodopinions' anagrammed gives 'oodpoisoning'.
'f'+'oodpoisoning'='FOOD POISONING'

'getting' is the link.

(Other definitions for food poisoning that I've seen before include "Botulism, for instance" , "Salmonella, etc." , "Acute illness caused by contaminated edibles" .)

I've seen this clue in The Times.
