Sampling Plan Control Frequency
Hello everyone,
We are producing food for animals and humans and i need to implement a sampling plan to control all our outgoing products.
for the frequency of control i will use this formula
frequency = production/100 x chance x seriousness.
this is the GMP+ requirement.
Do you think that i can use it also for human food?
Best regards
QA

Hi QA,
I think you lost a square root somewhere.
The "origin" and application of formula are described here -

The formula appears to require a lot of "informed" guesses ( as do most other methods of course :smile: )
Unfortunately not many worked examples are given.

Yes you are right. I forgot the square root.
Do you think that this formula could work for bulk product (milk, chocolate in powder)?
I apply it only for animal food for the moment.

Hi QA,
I would like to see the justification for the formula.
I didn't find any formula that's why i will use this one. Do you have any othee example that could be used for liquid (milk) and powder( chocolate)?
I made a lot of random analysis and i have a statistical datas of differents parameters( microbiology, heavy metals, fats...) But i don't know how to use those datas to establish a control frequency ?
Regards
Which judtification?

Hi QA,
I am not a statistical expert however this link is an illustration of one reason for my question -
1) i hope your not making human grade food on the same line as animal feed.....
2) i wouldn't use the same frequency for human grade---that would require you to assume the risks are the same---they are not
The two materials you mentioned (flour and chocolate) should both arrive with a certificate of analysis. Flour for ecoli in particular and chocolate for salmonella and ecoli
