Small motile bacteria penetrate far more easily through microscopic passages than non-motile moulds and yeast.

This document does not consider any international or national building standards or safety standards e. This document applies to the control of Legionella spp. Attention is drawn to ways of preventing problems with joints, which might otherwise cause leakage or contamination of product.

Hygienic Design Guidelines

Safe and Hygienic Treatment, Storage and Distribution of Water in Food and Beverage Factories Buy Buy Second Edition, March Since water treatments can be directly or indirectly part of the production process, this treatment should render the water microbiologically and toxicologically safe.

Materials covered include carbon-graphite, ceramics, elastomers and metals. The prevention and control of Legionella spp. Today, food process plants incorporate various multifunctional flow paths.

Hazards and risks associated with utility water can have significant implications on process reliability. It discusses how packing machines should be designed to comply with hygiene design criteria and thereby with guidelknes requirements specified in Annex 1 of the Machinery Directive. Gudelines Edition, October – This Guideline describes in detail the hygienic requirements of butterfly valves, slide gate valves and ball segment valves.

This guideline gives guidance for selecting the appropriate machine class and determines the machine class according to design principles implemented. Similarly, where a dry application precludes the use of guidelinse and liquids in cleaning, different systems may be suited, as described in EHEDG guideline, document First Edition, September – This paper identifies and defines critical design parameters for welded pipe couplings: Using the general criteria for the hygienic design of equipment identified in Doc 8this paper illustrates the application of these criteria in the construction and fabrication of closed process equipment.


A method for assessing the in-place cleanability of food processing equipment. Document was withdrawn in March The facultative anaerobic bacterium Serratia marcescens CBS The objective was to provide a reliable dismountable joint which is bacteria-tight at the product side under the conditions of processing, cleaning and sanitation.

This paper sets the minimum requirements for pumps, homogenisers and dampening devices for hygienic and aseptic applications. A method for assessing the bacterial impermeability of hydrophobic membrane filters. Microbiologically safe aseptic packing of food products NOTE: Second Edition, June – Applications in the food industry require that spray drying should meet hygienic processing standards and all components in contact with product should be hygienically designed and preferably be EHEDG approved.

European Hygienic Engineering and Design Group

Hygienic design of valves for food processing Buy Buy Buy Buy Buy Buy Buy Buy Second Edition, July – Valves are essential components of all food processing plants and the quality used strongly influences the microbiological safety of ehedgg food production process. It does not provide detailed guidance on specific manufacturing processes, products, buildings or equipment.

It is intended to appraise qualified engineers who design equipment for food processing with the additional demands of hygienic engineering in order to ensure the microbiological safety of the end product. Welding of stainless steel tubing in the food industry. Information is provided on the role of air systems in maintaining and achieving microbiological standards in food products.

Free Documents – EHEDG

Challenge tests for the evaluation of the hygienic characteristics of packing machines for liquid and semi-liquid products. Second Edition, May – Sterilization is a heat treatment aimed at destroying all vegetative microorganisms and spores to create a product which can be stored at ambient temperature yet minimizing public health hazard. Hygienic design of packing systems for solid foodstuffs.


Potential failure mechanisms and influences of manufacturing processes are also discussed. Thermal sterilisation is aimed at eliminating the risk of food poisoning and, when used in conjunction with aseptic filling, at achieving extended product storage life under ambient conditions.

This is the first in a series of documents that go beyond equipment design and covers installation and associated practices. Liquid foods containing particulates are inherently more difficult gidelines rocess than guidelinea liquids due to heat transfer limitations in particulateeliquid mixtures and the additional problems of transport and handling.

It mainly refers to the part of the weld in contact with the finished or intermediate product and the only welding method considered is the GTAW Gas Tungsten Arc Welding, commonly known as TIG without filler material autogenous weldsince this technique is capable of assuring the best performance in the execution of welds for the fabrication of thin wall stainless steel tubing.

Second Edition, June – Research has shown that hydrophobic membrane filters, with a pore size of 0. After documents 3 and 11this is the third test method in the series. First Edition, September – The introduction of the product into the processing system is a key step in maintaining the sanitation and integrity of the entire process.
