The time taken to complete the analysis can be a hindrance to the movement of products through the system. However, in the best hands different versions of the method can be used as a general screening tool, as a trait identification tool and in some laboratories as a trait quantification tool. Methods can be developed in individual laboratories but when transportation or trade is required it is imperative that the tests and the interpretation of those tests can be transferred with confidence between laboratories. A standard method is needed for comparison. Ring trials and collaborative studies have been conducted for a limited number of methods.
More work needs to be done.
The AACC has new method validations in the planning stages and we believe that other organizations such as the Joint Research Centre, Ispra of the European Commission and AOAC International have similar studies planned. Two ways to monitor competency and reliability for a laboratory are first to use an accreditation program with an ongoing check sample requirement and second to develop appropriate reference materials. In conclusion, test methods are feasible, but in need of validation and standardization to ensure consistent, reliable results. Despite the need for additional work to ensure good quality in all cereal products, from the grain to the finished breakfast cereal, there is testing and auditing of the food in the US food supply chain. All indications are that the quality of our food is very good.
