Hello,
I am assuming by your corrective action that the worm isn't related to a raw material sent to you by a supplier as you haven't stated what your product is? If this is a possibility maybe you should look at supplier controls to keep the raw materials worm free, verification would then be by supplier audit or checking what they send you.
If your action is to increase pest control and sanitsation have you had any record of any infestation? In this case corrective action would be to get rid of the source of the worms and verification would be that it has gone.
If you can't find the source of the worm then maybe you could identify the species, I am not a worm expert but maybe this would help pin down the source?
If none of this works I think all you can do is monitor complaints for a further occurance and assume that if there are no more whatever you have done has worked!

we making biscuit , corn snack and egg rolls
im assure that the worm is not coming from raw materials. because all raw materilas mixed will be baked and roasted at above 120 degree celcius.
and for the evidence of the worm is only a picture that is send by our customer ... so it is difficult to identify what species it is..
and because of it i assuming that flies can cause this in my root cause ... that is why i increase pest control ....
this is our first case regarding pest ... so there is no record of any infestation.
if im gonna verified it base on pest (flies) .. so the production area must free from flies right. insectkiller will help on to trap all the flies in the production area.
what i want to know is can i verified by the captured flies caught by the insectkiller since our insectkiller surely caught flies in the production area.
monitoring customer complaints occurance .... i like this one :)
what is the period suitable for the occurance ... can i make it for 3 months for no customer complaint related to pest
thank u .... its really help me a lot
