Myth 6: One critical control point at the end of a production line is enough In some simple production processes, a single critical control point (CCP) is sufficient. In other more complex processes or applications where multiple processes are involved, there is an increased risk of contamination and it may be prudent to install ‘in-process’ CCPs. Ultimately in many cases, in order to demonstrate due diligence and the ability to trace contamination to the source, it is nec- essary to establish CCPs throughout the entire production process.


Myth 7: The Global Food Safety Initiative is a certification


The Global Food Safety Initiative (GFSI) is a non-profit foundation man- aged by The Consumer Goods Forum and is dedicated to harmonising food safety standards around the world to make it easier for food manufacturers to comply with multiple regulations. Examples include the BRC Food Standard, IFS Food Standard, Safe Quality Food (SQF) Code and the FSSC 22000.


Myth 8: There is no need to keep records of product inspection The required length of time to hold onto product inspection system docu- mentation varies from region to region, as well as from manufacturer to manu-


facturer. However, it is in the brand owner’s best interest to retain perfor- mance records for as long as possible. Many food products, particularly dried and processed foods, have extended shelf lives. It is necessary to take this into consideration when planning and organising the data log- ging and storage system of a produc- tion line. This will ensure that food manufacturers can demonstrate due diligence should a problem occur.


Myth 9: Fault condition monitoring in inspection devices is not necessary Many food safety regulations now also require product inspection sys- tems to include advanced condition monitoring in preference to traditional fault monitoring. A fault monitoring system simply alerts operators when there is a fault in the product inspec- tion machine, whereas an advanced condition monitoring system gives early warning of adverse trends in per- formance before the failure actually occurs and before safety standards are compromised. This offers manufactur- ers the opportunity to plan mainte- nance and rectification work


Myth 10: All auditors operate with the same structure


It simply is not the case that all audits are the same. The audit proce- dure will vary according to the stan-

itting a tunnel metal detector to an existing con- veyor system has been simplified by S+S Inspection with the DLS metal dectector which can be split horizontally into two halves allowing the unit to be installed easily without disturbing the conveyor. Suitable for detecting all types of metal contaminants in bulk material to protect granulators and shredders, the DLS is said to reduce production downtime and maintenance costs to give quick cost recovery. The high detection sensitivity and robust construction delivers flexibility and reliability in even the harshest operating conditions.

dard the food manufacturer is expected to comply with, the auditing company, the records available from the manufac- turer and the particular application. Depending on the type of contaminant threat, certain food products require specific auditing procedures which should be taken into account when considering data logging and storage. Correctly documented and logged per- formance records can help manufactur- ers reduce audit times and the intensity of investigations. When documentation on product inspec- tion tests and contaminant detection is logically stored and comprehensive, there is less need to probe deeper for infor- mation on processes and valida- tion procedures.


Meeting industry Standards The standards governing the food industry are changing all the time as manufacturing processes evolve. Food manufactur- ers must have the correct product inspection systems in place to guaran- tee that they meet the increasingly stringent demands imposed on them by governments and retailers. Successful brand owners know they need to fully understand and comply with changing food safety regulations to ensure their products are fit for sale in regional and worldwide markets.


precise matching to specific performance require- ments and simplifies set-up and operation. Routine operational control is by three control buttons, a reset and a test with machine parameters being shown on eight LEDs in the case of the Primus version or a two line LCD display for the Sensity controller. Non- volatile memory stores data on up to eight user defined and three preinstalled products. The multi-channel technology detects all metals, including stainless steel and aluminium. When conta- mination is detected, the control system can initiate an audible or visual warning, activate a separation system or send a signal to a process control system to simply stop the belt.The robust design offers maximum resistance to interference and ensures high reliability both mechanically and operational- ly. The system is said to per- form well under harsh condi- tions for inspecting bulk materials and applications demanding high sensitivity proving the versatility and reli- ability of the DLS metal detection system.

Tester ensures gas detector compliance


Crowcon’s new T3 Gas Tester ensures the company’s portable, multi-gas detector complies with national or regional safety regu- lations. The device feeds the T3’s sensors a known concentration of gas, a process known as ‘bump-


ing’, to ensure the sensors are working correctly. When a T3 is inserted into the Gas Tester, the T3 automatically switches into ‘bump’ mode and either passes or fails. Once the test is com- plete the T3 is removed and the bump result is accepted by the user and logged in the T3. When the test has passed, the user is safe in the knowl- edge their detector is in good working order while, if it fails the bump, it informs the user that their instrument needs to be re-calibrated or serviced.


Capable of testing up to four gases in 60 sec- onds, it is a simple way of ensuring detectors are working correctly. Crowcon T: 01235 557700 www.crowcon.com Enter 316
