Bibliography

Describes a horizontal method for: - the detection of L. monocytogenes, and - the detection of Listeria spp. (including L. monocytogenes).

This document specifies a horizontal method for

• the detection of L.monocytogenes, and

• the detection of Listeriaspp. (including L.monocytogenes).

This document is applicable to

• products intended for human consumption and for the feeding of animals, and

• environmental samples in the area of food production and food handling.

It is possible that certain additionally described Listeria species may not be detected or confirmed by this method.^{[5],[10],[12],[14],[25],[26],[27]}
