1、安全管理2：联合利华公司的食品安全管理体系Safety,Health & Environment in Unilever and with pecific Reference to Food Safety Our ApproachApproach 布朗 联合利华公司 安全与环境检测中心主任Structure of this presentation1. I will explain Unilevers Business organisation to you. 2. I will describe the various groups within the organisation that
2、are involved in setting standards for Safety,Health & Environment and how they interact with each other. 3. I will explain to you how the standards are applied at Operating Company level and how they are audited. 4. I will go into a lot more detail about how one of the groups covered in 2 operates a
3、nd will use some specific examples involving food safety to explain this. Most of my examples will be taken from the area of chemical contaminants (I am a chemist), but they could equally apply to other food safety areas, such as microbiology.Unilevers Structure Each of the two Divisions is divided

6、tandards for Safety Health and Environment (SHE) Safety Health and Environment (SHE) policies/standards are agreed at the highest level. They are owned by Unilevers Executive Committee (ExCo - top board directors) and apply across the Foods and HPC Businesses. ie. We take Safety, Health and Environm
7、ental issues VERY seriously. The standards cover:- Product Safety- Health and Safety at Work- Environment Aim of the StandardsTo PROTECTHUMAN HEALTHENVIRONMENTDevelopment of standards for Safety Health and Environment (SHE) Standards are developed by experts and are agreed by Unilevers Safety Health
8、 and Environment Action Committee (SHEACO) on behalf of ExCo. Environmental Strategy is developed by the Unilever Environmental Group (UEG) on behalf of ExCo. Providing important input into these and into other Safety and Environmental matters, is a large group of full -time experts based within the
9、 Safety & Environmental Assurance Centre (SEAC). I will deal with this group in much more detail later. Implementation of Safety, Healthand Environment StandardsThe individual Business Groups/Categories are responsible for implementation of the standardsPosition of SEAC in relation toSHEACO and UEGA
10、ll SHE Policies areunderwritten by ExCoSafety Health and Environment Action Committee (SHEACO) Representation of Unilever world-wide:- - Involves both Foods and HPC Divisions.- Involves all Business Groups.- Involves all staff groups - business and central experts (e.g. SEAC) Sets global standards;
11、general, specific - non-negotiable. Provides guidelines. Assesses compliance through positive assurance. Corporate Audit as part of general auditing process- reports compliance into Unilever Chairmen. SHEACO Sub-CommitteesThere are 3 Sub-Committees of SHEACO:- Consumer Safety Sub-Committee. Occupati

18、 (many are involved with SHEACO). Operating Companies must apply the agreed standards and have control procedure to demonstrate they are doing so. Many have their own on-site quality control labs (eg microbiology, analytical laboratories) to do this. Foods Quality Assurance Group carries out regular
19、 factory audits to ensure the standards are being applied. Factories not reaching agreed standards are reported. The setting of raw material specifications is being co-ordinated across Unilever. SEAC Structure and FunctionSEACs availability to the BusinessFor normal enquiries SEAC Enquiry Service Av
20、ailable during UK office hours and will pass enquiries onto relevant SEAC experts. Response is normally within 1 working day. In Emergencies SEAC Support ServiceAvailable 24hrs/day, 365 days/year to tackle important time critical issues. People are on permanent stand-by, on a rota basis and with sop
21、histicated telecommunications back-up. Specific experts are also available via a telephone cascade system. Once products are on the marketExperts in SEAC continue to monitor the external world for issues that might affect our products, such as:- New Toxicological data. New Regulatory/Legislative pos
22、itions. Planned Government Surveys and the results of these (eg Foods Standards Agency Food Surveillance Surveys in the UK). Position of Key Opinion Formers (eg Scientific Committee for Food) Public Opinion and Customer feedback We are alerted by agencies (eg UK Pesticides Safety Directorate) about
23、contaminated commodities they have detected. As an exampleSome of The UK Foods Standards Agency Foods Surveillance Surveys to be carried out in 2001-2002 Survey of milk for Aflatoxin M1 and Ochratoxin A (Nov 2001). Dioxins and PCBs in shellfish (Jan 2002). Survey of paper and board for acrylamide mo
24、nomer and migration into foodstuffs (March 2002). Lead and cadmium in foodstuffs not included in the draft EC Regulation on lead and cadmium Nov 2001). Survey of individual phthalates in fatty foods (Jan 2002).All Brand Names will be published for all these surveys As another exampleIn Oct 2000, the
25、 EC Scientific Steering Committee published alist of issues they considered as having the potential to impact human health. These included:-Comparing this with a number ofissues of current relevance to the food industry, there is avery good fit:- Infectious agents Natural toxins Antibiotic resistanc
26、e Chemical pollution of the environment Bioterrorism Recycling of toxic substances Endocrine disruption Allergenicity Microbiology. DON, Aflatoxins etc. Veterinary drug residues. Pesticides, dioxins, polycyclic hydrocarbons. Malicious product tampering. DIPN etc in recycled board. Platicisers. Contr
27、ol of allergens in products. Our Involvement We are actively involved in monitoring and dealing with current and emerging issues that might affect Unilever. This involves:- Active participation with regulators, with scientific groups, with joint industry bodies etc to contribute to the scientific un
28、derstanding of the issues and to discuss how to deal with them.- Where appropriate, the carrying out of experimental work in order to obtain data to assess whether issues are likely to have potential implications for Unilevers product portfolio. - Having processes and expertise in place for dealing
29、promptly with issues that have become time critical. - Provision of advice and support to the Business based on the above activities. Some Examples of Pro-active Advice& Support to the Business Consumer Safety News - A SHEACO Bulletin which is sent out to SHE Co-ordinators and others each month, cov
30、ering topical SHE issues which might have an impact on our Business. Chemical Contaminants in Foods Database:- Provides data on all strategic surveys carried out on contaminants in food raw materials.- Classifies situations as High, Medium and Low Risk based on Raw Material type, Type of Contaminant
31、, and Source eg Black Tea + Organochlorine pesticides + India = High Risk Black Tea + Organochlorine pesticides + Indonesia = Low Risk Allergens Website - Very comprehensive support for the business on this subject.Our Commitment and Capabilities We have a great number experts, covering many differe
32、nt disciplines. These experts are highly experienced and are aware of all the major present and emerging issues We have a good depth of science, well-trained staff and “state of the art” laboratories & equipment. Some of our Equipment Gas Chromatographs with FID, ECD, FPD, NPD and other detection sy
33、stems. High Performance Liquid Chromatographs with UV, Fluorescence, Diode Array and Refractive Index detection. Capillary Zone Electrophoresis. 9 Mass Spectrometers, including high resolution double focusing, triple quadrupole, ion trap, bench top etc. Access to HR-NMR (400-700MHz) and LC-NMR. Acce
34、ss to FT-IR/FT-Raman Spectrometers, Atomic Absorption and ICP Spectrometers, Transmission Electron Microscopes, Confocal Microscopes, Scanning Electron Microscopes and X-Ray Micro-Analysis. This represents an investment of several millionOur Measurement CapabilitiesI am a Chemist with a specific int
35、erest in the trace analysis of chemical contaminants. But what does trace mean? 25 years ago, the major contaminants of concern forthe food industry were pesticides, and our limit of determination was measured in terms of parts per billion. This is 1 part of a contaminant in 109 parts of product. We
36、 used to say that detection of a contaminant at this level was like trying to find one person in the population of China! We now need to have a detection capability for some classes of contaminants (eg dioxins) measured in terms of parts per quadrillion, which is 1 part of contaminant in 1015 of pro
37、duct. So what is this like?Its Like:- Trying to find one person in a population 200,000x that of the earth. Detecting and accurately measuring one drop of an impurity in a volume of 2 million (5000 gallon) petrol tankers. The thickness of a piece of paper compared with the distance between the earth
38、 and the sun. So its quite easy really!So what sorts of things do we usethis capability on? Parts per billion levels of detection are required for most of the chemical contaminants of interest to the foods industry. Dioxins are the most obvious class of compounds where we need parts per quadrillion
39、levels of detection because :- - Of their toxicity- There 17 different dioxins and furans which have significant “dioxin-like” toxicity, all of which need to be analysed for. Food taints (off-flavours) is an area requiring almost this level of sensitivity. Until the taint has been identified and qua
40、ntified, it is not clear whether it represents a quality issue, or a safety issue, or both. An Example of a Food Taint Problem3rd Party Supplier WarehouseStored in paper sacks on wooden pallets.Unilever Manufacturer of a beer clarification product.Supplied to a German Brewery - used to clarify beer.
41、1 million bottles of beer so badly tainted that it is undrinkable!Action Taken etcPrior to SEAC becoming involved Samples of beer and of clarification product sent to four universities and contract analytical laboratories - none of them was able to identify what was causing the problem. After SEAC b
42、ecame involved The smell of the taint implicated either a trichloro-phenol or anisole as the likely cause. Trichlorophenols are used as wood preservatives and the wooden pallets were thought a possible source, but none could be found. Tribromophenols are also listed as wood preservatives, so we look
43、ed for these compounds in the clarification product with our equipped tuned to maximum sensitivity for these compounds. 2,4,6-Tribromophenol was found in the clarification product and later in the wood from the pallets. 2,4,6-Tribromoanisole was then found in the beer. Production of Taint From Wood
44、Preservative2,4,6 -Tribromophenol- Wood Preservativetransferred from pallets to clarification product.2,4,6 -TribromoanisoleTaint Threshold = 4pptFound in beer = 10ppt!Another example where the humannose is invaluable Therefore, wood smoke smell = possiblemicrobiological spoilageOur Capabilities In
45、The Area ofPhysical ContaminantsIn the unlikely event of being faced with a physical contaminant issue:- FT-IR allows us to quickly identify organic contaminants such as plastics. Various microscopy techniques allow us to easily identify objects such as plant debris (leaf or ear of corn etc). X-Ray
46、Microanalysis allows us to identify types of stainless steel, types of glass etc just like the forensic science service. This information would enable us to quickly identify the source of the physical contaminant and eliminate it. Some of the issues are very complex!Example 1 - Di-isopropylnapthalene(DIPN) in recycled boardThis is DIPN, which is used as a solvent in carbonless copy paperFacts DIPN finds its way into recycled board because it is difficult to eliminate carbonless paper from the paper recycling process. It has been show
