為什么我們要在CIP后檢查我們的表面？
為了遵守HACCP要求，加工商需要確定CCP（關(guān)鍵控制點(diǎn)）和/或其生產(chǎn)工廠內(nèi)可能導(dǎo)致產(chǎn)品污染/故障的區(qū)域?，F(xiàn)在可以使用獨(dú)特的Bactiscan系統(tǒng)在CIP（現(xiàn)場清潔）后檢查表面區(qū)域，使處理器能夠遵守盡職調(diào)查。
我們應(yīng)該多久檢查一次表面區(qū)域？
不銹鋼表面，其中一些位于生產(chǎn)區(qū)域內(nèi)，應(yīng)定期檢查，尋找由清潔系統(tǒng)差、例如噴霧球故障引起的生物膜和細(xì)菌生長區(qū)域，在生產(chǎn)過程中的任何時(shí)候都可能出現(xiàn)缺陷，或者當(dāng)物品進(jìn)行CIP清潔時(shí)，這些區(qū)域隨時(shí)都可能導(dǎo)致產(chǎn)品污染，因此建議盡可能頻繁地進(jìn)行檢查。
我使用了傳統(tǒng)的方法來驗(yàn)證我的CIP，現(xiàn)在好的方法是什么？
使用EIT International的Bactiscan進(jìn)行實(shí)時(shí)掃描。該設(shè)備使處理器能夠?qū)崟r(shí)清晰地看到生物膜，使他們能夠?qū)υ搮^(qū)域進(jìn)行拭子檢測，以識(shí)別細(xì)菌數(shù)量。
我們已經(jīng)看到人們使用紫外線來尋找生物膜，為什么不使用紫外線代替Bactiscan呢？
Bactiscan在紫外線光譜的邊緣工作，這是一個(gè)旨在檢測細(xì)菌周圍蛋白質(zhì)外殼并分離紫外線不可見的生物膜的系統(tǒng)，Campden BRI提供的驗(yàn)證文件證明了這一點(diǎn)。
生物膜在表面變硬并且不能被CIP沖洗掉，這是正確的嗎？
根據(jù)我們的經(jīng)驗(yàn)，一些生物膜隱藏在玻璃狀表面后面，這是通過連續(xù)洗滌和化學(xué)硬化引起的，當(dāng)采集拭子時(shí)，拭子技術(shù)無法檢測到它們。Bactiscan可以突出顯示這些區(qū)域，并且需要進(jìn)行研磨工作來去除膜以測量細(xì)菌數(shù)量。對加工商來說，危險(xiǎn)在于這些薄膜可能在生產(chǎn)過程中變得松散，并將生物膜釋放到產(chǎn)品中。
你的檢查員會(huì)在我的工廠里哪里尋找這些生物膜？
我們建議您隔離一條線并掃描該線內(nèi)的區(qū)域，以便接觸產(chǎn)品的表面。例如，我們近檢查了一個(gè)無菌水容器，因?yàn)檫@是在尋找發(fā)生的污染時(shí)的后一次檢查。該容器有嚴(yán)重的生物膜，在生產(chǎn)線裝滿產(chǎn)品之前，這些生物膜明顯會(huì)釋放到終沖洗液中，污染了整個(gè)生產(chǎn)線。
使用Bactiscan進(jìn)行測試的環(huán)境問題是什么？
EIT International的Bactiscan系統(tǒng)具有電子傳感器，可以在沒有任何耗材的情況下使用多年，因此非常環(huán)保且具有成本效益。
你能證明測試的準(zhǔn)確性嗎？
Bactiscan設(shè)備包括實(shí)時(shí)掃描儀和測試片，用于在表面復(fù)制生物膜和細(xì)菌，以證明準(zhǔn)確性。該過程已通過Campden BRI驗(yàn)證。
您將用于測試的設(shè)備的安全性如何？
Bactiscan使用輕型電池供電的電子傳感器和發(fā)射器來照明表面。
使用Bactiscan時(shí)應(yīng)采取哪些安全措施？
我們建議檢查員在使用Bactiscan時(shí)佩戴防護(hù)眼鏡等適當(dāng)?shù)难鄄糠雷o(hù)用品。大多數(shù)生產(chǎn)設(shè)施都將在原地安裝安全眼鏡。聚碳酸酯制成的安全玻璃鏡片可以自然阻擋99.9%的紫外線。因此，即使是透明的安全眼鏡也能提供出色的保護(hù)。但是，如果您需要特定的紫外線防護(hù)，只需簡單的在線搜索即可提供其所在地區(qū)的供應(yīng)商列表。
Bactiscan測試需要多少停機(jī)時(shí)間？
在大多數(shù)情況下，只要表面可以被Bactiscan照明，就不需要停機(jī)。Bactiscan能夠在例如大約30分鐘內(nèi)檢查空筒倉。
你的測試方法能在我的灌裝機(jī)上找到產(chǎn)品殘留物嗎？
Bactiscan能夠識(shí)別包括灌裝機(jī)在內(nèi)的許多表面清潔不良的區(qū)域。
Why should we test our surface areas after CIP?
In order to comply with HACCP requirements, processors need to identify CCPs (Critical Control Points), and/or areas within their production plant that may cause product contamination/failure. Examination of surface areas after CIP (Clean in Place) is now possible using the unique Bactiscan system, allowing the processor to comply with due diligence.
How often should we examine the surface areas?
Stainless steel surfaces, some of which are positioned within the production area should be examined regularly, searching for areas of biofilm and bacterial growth caused by poor cleaning systems, spray ball faults for example, defects may occur at any time during production, or when the item is CIP cleaned, these areas may cause product contamination at any time, so examination as frequently as possible is recommended.
I have used traditional methods for validating my CIP, what is the best methodology now?
Scanning in real time using EIT International’s Bactiscan. This equipment enables the processor to clearly see the biofilms in real time, enabling them to take swabs of the area to identify bacteria numbers.
We have seen people using U.V. to try to look for biofilms, why not use U.V. instead of Bactiscan?
Bactiscan works on the fringes of the UV spectrum, it is a system that is designed to detect protein shell around the bacteria and isolate biofilms that are not visible with U.V. and this is proven with validation documentation provided by Campden BRI.
Is it correct that biofilms become hardened on the surface and cannot be washed off by CIP?
It is our experience that some biofilms are hidden behind a glass-like surface caused through continuous washing and chemical hardening and when swabs are taken, they are not detected with the swabbing technique. Bactiscan can highlight these regions and abrasive work is needed to remove the film in order to measure bacteria numbers. The danger for processors is that these films may become loose during production and release the biofilm into the product.
Where would your inspector look for these biofilms in my plant?
We would recommend that you isolate a line and scan all areas within that line, so surfaces that are in contact with products. For example, we recently checked a sterile water vessel as this was the final examination when searching for a contamination that had happened. The vessel had serious biofilms that were obviously releasing into the final rinse before the line was filled with product, contaminating the whole line.
What are the environmental issues with testing using Bactiscan?
EIT International’s Bactiscan system has electronic sensors that can be used for many years without any consumables, so extremely environmentally friendly and cost effective.
Can you prove accuracy of the test?
The Bactiscan equipment comprises of real time scanner and test piece to replicate biofilms and bacteria on surfaces, proving accuracy. This process has been validated by Campden BRI.
How safe is the equipment that you will use for the tests?
Bactiscan uses lightweight battery operated electronic sensors and transmitters to illuminate a surface.
What safety steps should I take whilst using Bactiscan?
We recommend that the inspector wear adequate eye protection in the form of protective glasses whilst using Bactiscan. Most production facilities will have safety glasses in situ. Safety glass lenses made of polycarbonate will naturally block 99.9% of UV light. So, even clear safety glasses will provide excellent protection. However should you require specific UV protection, a simple on-line search will provide a list of suppliers in their area.
How much downtime is needed for the Bactiscan test?
In most instances downtime is not required as long as the surface can be illuminated by Bactiscan. Bactiscan is able to examine an empty silo for example in approximately 30 minutes.
Would your test method find product residues on my filling machine?
Bactiscan is able to identify poorly cleaned areas of many surfaces including filling machines.
