Sir: Scandals such as Horsegate and prawn farming slavery have highlighted that it is easy to bypass checks, and reinforce the need for greater traceability and transparency across supply chains. The food crime unit is a step in the right direction while moves to improve collaboration in auditing will help reduce duplication of effort. Complete traceability will require retailers to visit supplier sites first hand as opposed to relying on word of mouth.
