Good day and Hi all,

 

I have few questions on X-ray monitoring. FYI purpose of using x-ray is used to detect bone in raw chicken breast.

 

Are there any requirement from BRC mention on the frequency of x-ray monitoring and verification? 

 

and for the x-ray validation was done 30 times (top, middle and bottom) using 5 test pieces (Fe, Stainless steel, Aluminium, Ceramic and Soda Lime) and bone recommended by vendor. Is it the correct way and sufficient?

 

while for the monitoring form, is it plausible to monitor using bone and one of the low density test piece only?

 

Thanks.

Greetings Yuna,

 

For the validation it's ok in general the way you did it, but I have a couple questions, concerning the bone test sample. Specifically, did you use different sizes, with emphasis to small ones and also, did you simulate real scenario?? Meaning did you place a small bone (more importantly) intentionally in an end product (chicken breast and run it through the X-ray ? And one of the best tests would be to take a chicken breast that is higher than the average weight / size and place in an as small as possible bole in the geometrical center of it.

 

For the monitoring / verification there are no specific rules, but I have seen 2 common practices, both deriving from risk assessment. First and more robust is to pass a sample every hour of production (it also ensures that in case you have a problem you won't lose an entire production, but only an hour's worth). I have found as well as been informed that testing in less than an hour makes it very tedious and taxing during the production and there is no actual gain, even though there is no limit in food safety!!!

The second (if the risk assessment "allows" it) is to pre-decide that for example you want to have 4 tests in a shift and then spread them evenly in the shift hours.

 

Regards!

Hi Evans.X,

 

Thanks for the infos and reply.

Yes, i used the few hard bone samples (prepared by myself) with ( Example: Length X Width X Thickness: 2.68mm X1.82mm X1.19mm) which i insert in the chicken boneless breast to carry out the validation.
