Approved Maintenance Compounds (Non-Dairy) Manual

4 Criteria for Disinfectants for Foot-and-Mouth Disease Responses

Amendment 0

July 2007

4.1 Introduction

Disinfectants are used to inactivate the foot-and-mouth disease (FMD) virus to prevent the spread of the disease to animals. FMD virus is extremely sensitive to changes in pH and the most effective disinfectants are those with a pH below 3 (acidic) or above 11 (alkaline). Part A lists compounds currently approved for use by operators processing non-dairy animal products who are operating under the Animal Products Act regime. These compounds, when used at the dilutions indicated, are expected to be suitable for cleaning and disinfection in the event of a foot-and-mouth disease emergency being declared.

4.2 Requirements

4.2.1 Specifications

Compounds must conform to one of the following categories:

• acidic disinfectants suitable for a wide range of surfaces without the risk of corrosion;

• alkaline disinfectants (non-corrosive) giving a degree of metal protection and which are suitable for a wide range of surfaces without the risk of corrosion;

• alkaline disinfectants (corrosive) suitable for drains and sewers and surfaces where corrosion would not be regarded as critical.

Note: the product label should give a general indication as to the suitability of the disinfectant for different types of surfaces.

4.2.2 Dilution

The final strength of the disinfectant, when mixed with water, must be a volume/volume percentage for fluid compounds or a weight/volume percentage for solid state compounds. The final strength must achieve a pH of pH 11 or greater for alkaline disinfectants or pH 3 or less for acid disinfectants.

4.2.3 Stock Level

The quantity of disinfectant that could be available either:

• on call; or

• after 48 hours.

This information is intended to be used as a guide to the availability of a particular disinfectant should the need arise. It is appreciated that for some compounds large quantities can be manufactured within a short period of time whilst for others the replenishing of stocks will take longer. Stock levels may be listed under either or both of these headings.

4.3 Procedures for Obtaining Listing of Compounds

Manufacturers who consider that a currently approved compound will meet the requirements for disinfectants may request to have products listed in this section.

The information required, in addition to that specified in the procedures for gaining compound approval or re-approval of approved compounds (see Part C) is:

• specification;

• dilution rate;

• stock level.

4.4 Obligations of Manufacturers

Foot-and-mouth disease would seriously impair New Zealand's ability to trade in agricultural products. The resumption of trade will depend on the efficiency and effectiveness of our ability to respond to an outbreak. Maintenance compounds listed in this section could form part of New Zealand's response to an emergency and it is essential that all information published in this list is valid. Any change in formulation, availability, manufacturer or distributor must be notified to:
