Every food processing line benefits from hygienic engineering and design, but fish processing is particularly receptive for microbiological contamination. That’s why every fish handling process should comply with the latest EHEDG guidelines. It is also why EHEDG published a new guideline dedicated exclusively to fish processing.

 

Food Technologist Sanja Vidaček Filipec is Associate Professor at the University of Zagreb and the Chair of the EHEDG Working Group Fish Processing. She talks about the unique hygienic design challenges in fish processing and explains how the new EHEDG Fish Processing Guideline 49 can help to tackle fish processing challenges and minimise contamination risks.

 

What sets industrial fish processing apart from other food handling processes?

Sanja Vidaček Filipec: “Firstly, fish come in all sorts, shapes, and sizes and varieties differ greatly around the world. Consequently, there are many technical approaches to processing fish. This represented a challenge for our working group members who committed themselves to develop a comprehensive and international industry guideline. Secondly, fish processing environments are always humid, and humidity is the single most compromising factor for food safety because it manifolds the risk of microbiological contamination. Thirdly, since fish is highly perishable, speed and efficiency are particularly important in fish processing, even more so than in processing red meat or even poultry. That’s why fish trailers freeze their fish right after each catch. It is also why modern industry fish processing lines that make good use of EHEDG guidelines not only optimize their food safety and food quality conditions but also their efficiency and productivity.”


Why did it take until now to develop this guideline?

“In the past years EHEDG published technical guidelines on specific areas of open processing that also apply to fish processing - we refer to quite a lot of them in this new guideline. It took quite some time before all those separate guidelines were detailed enough to support a comprehensive guideline on fish processing. In the meantime, our working group focused on developing a set of fundamental hygienic design principles that would apply to different types of fish processing plants, in line with the basic hygienic design principles in EHEDG Guideline 8. This EHEDG Fish Processing Guideline 49 offers just that and more because it also addresses hygienic aspects that are specific to contemporary fish processing techniques, like the use of vacuum systems to remove by-products. EHEDG Fish Processing Guideline 49 took several years to develop because there are so many food safety and food quality determining aspects to industrial fish processing that had to be investigated. On a detailed level, every fish processing plant has to apply this guideline in accordance with their circumstances.”


Who should read this guideline?

“Everyone involved in the processing of salmon, white marine fish, and freshwater fish can put this guideline to excellent use. EHEDG Fish Processing Guideline 49 is even applicable for fish processing on fishing vessels. Overall, this new guideline offers great value during the procurement process, the plant design, installation, and microbiological sampling phase. It provides a comprehensive overview of all the everyday hazards and challenges of fish processing and does so in clear, non-technical descriptions. All members of our working group wanted to make sure that everyone could understand the principles. We expect this guideline to contribute to a more widespread awareness of food safety and food quality determining aspects of fish processing on all levels in the industry. Now every decision-maker in the fish industry can refer to this guideline and specify what is meant when requesting hygienic design solutions. Moreover, equipment producers striving to certificate new equipment for the fish processing industry know what criteria their components have to comply with. The EHEDG Working Group Fish Processing is convinced that this guideline will help to optimise food safety and food quality in fish processes all over the world.”

Guidelines Pasteurisation & Sterilisation

EHEDG Guideline 1 & 6 ready for download

Chairman EHEDG Working Group Heat Treatment  Bengt Eliasson: "These two completely renewed guidelines on pasteurisation and sterilisation of liquid food offer new insights in how to optimise food safety, food quality, productivity and energy efficiency of continuous pasteurisation and ultra-high temperature sterilisation processes.”

We’ve been pasteurising and sterilising for ages. Why renew these guidelines now?

Bengt Eliasson: “Pasteurisation and sterilisation are well established, most widespread and important methods to preserve liquid food. This is why the initial guidelines for continuous pasteurisation and sterilisation were the very first guidelines that EHEDG published to optimise food safety in the food industry. That was back in 1992. Since then, new technologies and new legal requirements and regulations have emerged. EHEDG translates all those new developments into practical guidelines that the food industry and its suppliers can work with to comply with all requirements. EHEDG also wants to help its community members to find the information they need more efficiently. Therefore, all EHEDG working groups recently agreed to structure their guidelines in a new format. So now the guidelines for the pasteurisation and sterilisation of liquid food are published in this new, more user-friendly format.”

So what’s new?

“These new guidelines contain hands-on information aimed at food producers, machine equipment developers and plant designers who need to comply with the latest food hygiene regulations. The old versions of these guidelines focused primarily on milk production, thus limiting the possible applications of these guidelines. The renewed guidelines also cover the production of other liquid foods and high acid products like fruit juices. They provide practical technical frameworks that include a wide array of topics ranging from general considerations regarding the applied pasteurisation and sterilisation techniques to hygienic process design and technical matters concerning effective flow diversion, recirculation and cleaning and control processes. All information is presented in line with the new EHEDG guidelines format that structures information into categories like design, production and maintenance aspects. For those who want to go one step further, these guidelines also contain useful information on techniques to optimise energy efficiency and minimise maintenance intervals.

Do these renewed guidelines cover everything we must know?


“There’s always more to know, but these publications are very comprehensive. They contain guidelines that help readers to make sure that correct temperatures and processing conditions are maintained, that any unacceptable deviation in key process variables results in an automatic flow diversion or shutdown and that the production process is stopped before fouling becomes significant or before thermophilic bacteria growth becomes too intensive. The guidelines relate to the importance of hygienic design in the different stages of the pasteurisation and sterilisation processes. The guideline on pasteurisation, for example, states that the process equipment downstream of the holding tube must be hygienically designed and hence cleanable, possible to disinfect and bacteria tight. This guideline furthermore offers means to prevent the risk of mixing pasteurised and unpasteurised products. Moreover, both of these guidelines even include practical guidelines on how to utilise hygienic design principles to tackle specific regional legislation requirements.”

You mentioned energy efficiency. How sustainable is hygienic design?


“Energy efficient solutions in general, and heat recovery techniques in particular, are becoming more and more important for food producers. They are willing to invest in new techniques to optimise efficiency - not only to save energy, water, and chemicals but also to maximise their productivity by minimising cleaning time intervals and waste. Hygienic design offers many possibilities to save energy and minimise downtime. These guidelines contain several chapters that help EHEDG community members to make sustainable choices to minimise contamination risks and to save energy and money. The guidelines illustrate that investing in hygienic design solutions is economically viable. By applying hygienic design we can shorten CIP times, make the production more efficient by overall increasing availability and reduce the total cost of production. Since investing in hygienic design improves overall efficiency, it’s is a cost saving investment it. It also avoids recalls and public health hazards.”

Is there a link between hygienic design and new forms of energy re-use?


“The guidelines also illustrate how certain systems work, for example, a system that enables producers to preheat their products by heat recovery using a secondary circuit. Heat recovery systems are in general more complex regarding plant design, but the results are very satisfying because they require significantly less energy. Even when investment budgets are limited, these guidelines offer interesting options. In sterilisation processes, for example, it’s also possible to preheat a product after the holding section with a sterilised product in a regenerative heat exchanger, making for less complex plant designs and realising the same amount of energy savings.”

So it’s not the germs we need worry about then - it’s our inner terrain.


“Exactly. And let me conclude with yet another quote of the great Louis Pasteur, who not only discovered the power of pasteurisation, but who also had a very clear vision on how to handle food safety in general: ‘Whether our efforts are, or not, favoured by life, let us be able to say, when we come near to the great goal, I have done what I could.’"
