    Gudjon,

    According to the US National Seafood HACCP Alliance's "Sanitation Control
    Procedures for Processing Fish and Fishery Products Manual" Chapter 8, page
    8-8, a rat can pass through an opening of 0.5 inches (12.7 mm). The manual
    can be downloaded from SeafoodNIC (http://seafood.ucdavis.edu) using Acrobat

    Subject: Exclusion of rodents from factories

    Dear members

    Does anyone now what is believed to be the adequate grid size in the
    context of preventing rodents (mainly rats) from entering an establishment.
     From what I have read, a 10 mm grid should be sufficient. Does anyone have
    a suggestion to where I could find more information regarding this subject.

    Best regards

    Gudjon Gunnarsson
