White Horse Laboratories April 2012 Summary and Counterfeit Detection Report

White Horse Laboratories April 2012 Summary and Counterfeit Detection ReportFollowing from our discussion in our last two reports, we saw a further average drop to 62.5% in April from 63% in Q1 and 68% in 2011. While there are certainly many factors that are behind the statistic, we are continuing last week’s poll on what YOU think is behind the numbers.

We will also be focussing our Weekly Poll Questions throughout 2012 towards industry perception regarding inspection related issues. What is your opinion about the effects of increase counterfeit awareness and legislation? Post your vote on this week’s poll at http://conta.cc/IaQoNd.

We’ll post the results here, in our monthly newsletter, on our website, and our new Twitter page, @whitehorselabs.
