Although the Listers Group claim they have "examined its supply chain in order to identify area where there is a risk of slavery or human trafficking," they don't describe how they have examined their supply chain, neither do they give any procedures, findings of this examination nor did they explain what part of the supply chain they examined? This quote also insinuates that the examination was a 'one off examination' and that they have identified the risks and these are the risks they make their suppliers aware of and to prohibit, however, there is no evidence to suggest that the Lister's group assess the risk of modern slavery and trafficking in their supply chain continuously or more than the time at which they wrote this statement, therefore, the answer is no.
