Health officials believe they have found the reason why finding the illnesses from the salmonella outbreak took so long. They believe it could have been detected earlier if it weren’t for the state laws and regulations, which slow the identification process. Msnbc.com actually did a survey, which found that only two thirds of the states require their labs to check the salmonella specimens that could confirm an outbreak. The other one-third is only voluntary if it is even done at all. The states that are required usually test every sample they have with a process called PFGE, where as certain states such as Texas only screen about half of the collected samples. Because many states do not check every sample, many outbreaks go undetected for quite some time; thus, delaying the warnings and recalls. Due to this find, many people are pushing for mandatory testing using PFGE. This mandatory testing though could be hard on some laboratory companies due to the cost and labor needed.
