I'm interested in number 5. I would argue again this is more likely to be a quality issue than a food safety one. What's likely to grow if O2 % is OOS? Is it actually dangerous? It probably depends on the product.
Yes, O2 concentrate depends on product. For red meat O2 is mostly added to maintain the red colour. --> No
CCP.
For chilled RTE O2 is lowered to reduce growth of aerobic bacteria including pathogens e.g. Listeria and Salmonella. It also has to be higher then 0,2% to reduce the growth of Clostridium B. and other anaerobic pathogens.There are scientifical reports for this from TNO-Netherlands. However I do not have these. Limits for these kind of products are mostly 0,2%-1% O2. If only 1% is used, I like to see a validation why anaerobic pathogens are no issue.
I'd be fascinated how you monitor number 8!
I would like to know about the V & V on no.8
I do not know what you mean with V & V, but I assume it is like monitoring, critical limits, corrective actions.
I have seen several monitoring methods, which are all also known from sealing checks on sealed packings.
1) after vacuum machine the packing (in boxes) is done manual. Workers have to touch the product and will notice when the packing is not vacuum. They need to record the failed packs in an hour. The NC pack is repacked and vacumised again. If there are more then X NCs in an hour the supervisor need to be informed, line will be stopped and vacuum machine will be checked.
2) every hour one packing for each mold is visually checked in the seal. Record if seal is intact/not intact. If not packs from the last hour need to be visualy inspected and if needed repacked.
3) every hour one empty packing is made and with a needle piched and with a manual pump, air is pumped in the packing. If 50 pumps do not lead to damaged packing it is good.
4) every hour a empty packing is made and is cut open by the operator. The thickness and strongness of the seal is checked.
ad 1) I had one customer with this
CCP and it lead to discussions every visit. Also because the critical limit was set on 50 leakages an hour and they would find a maximum of 6 an hour. (but normally no leakages were observed). It was more a process control monitoring. They have, after 6 years, let go of this
CCP. They pack fresh red meat, used for cutting up and further processing by butchers. These customers have enough knowledge to know the difference between vacuum and not vacuum and will sent back the products if this is wrong.
A similar
CCP/monitoring is seal checks on sealed packings. Methods 1, 2 and 4 seen for these checks, but also checks with a water basin (if there are no visual bubbles, there is no leakage), with pressure tank or with specific leakage detector equipment. However most common for sealed packings is method 1. This
CCP was quite common for 5-6 years ago, but is more and more reduced to 'just' a quality issue or a process monitoring.
Surely number 10, spoiled food is a quality issue, and is too much preservative really a food safety one?
Depends on the wording of the hazard in the risk assessment. Are we sure these are not carcinogenic? If the hazard is documented as a double dose it is a different risk then if the hazard is documented as a little bit more.
But I agree, that I do not see this
CCP often anymore.
In feed industry adding additives is almost always a
CCP.
For coding, perhaps it's a language issue but if you're considering BBD, then it's definitely not a food safety issue because where dates are critical, they are use by dates (and even then it's arguable whether thats a CCP. Most chilled food I've worked in with short shelf life spoils long before there's a food safety issue so I'd argue it would be apparent to the consumer!)
Yes, you are right. I meant used by date (I always forget thesre are also 2 different codes in English language). I think these are rather critical in RTE. There are surely ready to eat products where pathogens can grow, before spoilage is visible. Consumers are not very smart relating to food products/ food safety. We have discussed in another thread, that the majority of the consumers throw away products on the BBD/ CBD/UBD even if the product is still fine (e.g. whole fresh fruit, milk, yoghurt etc) My parents in law were eating cream cake and were saying that it had a very funny taste, but just eat it anyway because the label said that it would still last for 3 days and it wat bought that moring. When I tasted it, I recognised the cream to be spoiled. As you know this is very good recognisable and even though they tasted that it was nog good, they rely on the coding and eat it anyway. Ready to eat meals are mostly foreign tastes. I mean it is mostly: Chinese, Thai, Indonesian, indian, Mexican, Italian, Greek, Cadjun, etc. All of them with strong and sometimes unfamilair tastes. I do not know If I would recognise an off flavour or off taste in these products. So when there was a mistake in the code printer say, instead of 12-01-2012 it was 11-02-2012, I am sure some consumers will eat it and might get sick.
I think Coding control under no. (11) should really be supported by "Pre-Start Up" and "Positive release Management".
Of course this is a start up thing, but why can a start up check not also be a
CCP?
If it is documented as a part of the positive release, then it surely is a
CCP.
