DESCRIPTION:A lattice statistical-mechanical model with exact topological 
 defect lines exists for any fusion category\, In this talk I describe how 
 to generalise these methods to construct conserved currents in such lattic
 e models. The currents are defined by terminating the defect lines\, and a
 re conserved when they satisfy a lattice divergence-free condition. The ca
 tegorical structure allows one to find fractional-spin conserved currents 
 in many (but not all) models\, and in all known cases the corresponding la
 ttice model is integrable. The method therefore gives a linear way of &ldq
 uo\;Baxterising&rdquo\;\, i.e. building a solution of the Yang-Baxter equa
 tion out of topological data.&nbsp\;
