Hello, 

Can you advise me regulation or standard which give me exactly guidance how to take sample form dry chicken meat? 

How many incremental samples should be take for testing of Salmonella, Enterobacteriaceae, Yeast, Mould and heavy metals  in case of already packed products? 

and how many  incremental samples should be take for testing of protein, fat, moisture etc in case of bulk product?

hmmmmm 

 

do you start with fresh meat?  Has it been sampled prior to or at arrival?  


Because we always have is never an appropriate response!

Apologize that i am not in Chicken Business.

 

Dry meat = ? RTE ?

Local Regulatory Requirements Exist ? = ?

Customer requirements exist ? = ?

 

There are many possible generic answers to yr sampling question depending on factors like margin of error, confidence level, decision rules.

Pls inform as to the specifications for the items stated.

 

Just as an example for estimating a mean, see -

Scampi, 

this testing is for finished product,

 

Charles, 

unfortunately  there are not giving exactly guidance and if we ask consumers answer will be every day, and  this is not cost effective. 

But I am asking another question, may be i did not formulated correctly. I want to know how much should be incremental samples from 4  tone meat ?

Below you'll see a sampling plan that's designed for FTM, but you may find the schedule to be of assistance in how to attain your representative samples for a lot

 

Start-up plan

This plan is used when the equipment is first installed, when major components are replaced (e.g. a separating drum or filter, separating screens, screen plates or perforated screen, feeding screw [i.e. worm], etc.) or when major repairs are made.

Under this sampling plan the operator must test each lot for calcium, protein and bone particle until 10 consecutive lots are in compliance. Once this is achieved, the monitoring plan can be used.

The sample to be analysed shall consist of 20 sub-samples taken during the lot run. If the shift is 8 hours (480 minutes) sampling must be done every 24 minutes (480/20 = 24 minutes). Likewise, if the scheduled lot run is 6 hours (360 minutes) sampling must be done every 18 minutes (360/20 = 18 minutes).

The shift must be a minimum of 4 hours to be considered in this start-up plan, unless the operator's normal operating shift is less than 4 hours.

Each sub-sample should be about 30 grams. The samples may be placed in the same container (e.g. a plastic bag) so that at the end of the lot run it will contain about 600 grams of product.

The tested lots are to be held until receipt of an acceptable laboratory report.


Because we always have is never an appropriate response!

For packed, pls refer the link in my previous post. Some input data must be provided/estimated so as to make  estimates of a mean for yr micro items 2-4 and heavy metals..

 

The practical problem is that the theory assumes random sampling however a packed lot typically restricts the available sampling locations. So equation is approximate.

 

The total size of lot is theoretically irrelevant if sample taken is random and size approx less than 10% of total which it very likely will be.

 

For Salmonella I suggest you consult -

 

https://www.fda.gov/...s/ucm063335.htm

 

For a finished presented bulk lot, one can visualize as appropriate packed units and repeat the exercise above. Scampi's methodology (systematic sampling)  will probably be (much) more accurate if access during formation is possible.


Kind Regards,

 

Charles.C
