National Public Health Week -- APHL Honors Public Health Laboratories

By Mary Shaffran, Senior Director, Public Health Programs, APHL

Along with our partners, the public health laboratories are working to keep communities healthy. Laboratorians work behind the scenes. Public health laboratories serve as the nation’s early warning system for diseases and other health hazards. When health risks emerge or re-emerge, public health laboratories analyze the threat, provide the answers needed to mount an effective response and act to protect the public in collaboration with other decision makers. They protect our health by monitoring continuously for diseases and other health hazards.


Just a few of the things that laboratories are doing every day to make sure that you and your neighbors are healthy: 

- Public health laboratories in every state are the backbone of our nation’s infectious disease surveillance networks. They are analyzing infectious diseases such as influenza to determine if they are changing and reporting this information to public health officials so they can determine effective prevention measures. [More on the Infectious Disease Program]

- More than 11,000 babies are screened daily for potentially life-threatening genetic and congenital disorders.
  • Matt and Noelle Bamonte discovered that their seemingly healthy baby boy had PKU, a serious disorder that can cause brain damage if not treated from a very early age. Noelle is certain that without laboratory screening, her little boy would have been vastly different. Now, aside from a strict diet, he lives a normal life! [More of their story]
- Public health laboratorians confirm whether people are infected with sexually transmitted diseases, and confidentially report back the results so that people can be treated and others are not exposed. [More on the Sexually Transmitted Disease Program]

- In order to detect foodborne outbreaks and ultimately keep Americans safe from foodborne disease, public health laboratorians test human specimens and food samples for bacteria such as Salmonella and E. Coli.
  • In 2006, the New Mexico public health laboratory pinpointed the exact source of the E. Coli that made its way into spinach and made hundreds of people sick. [More on the E.Coli outbreak]
- Public health laboratorians test environmental, clinical and food samples to determine whether they contain hazardous agents in order to protect Americans from terrorist attacks, and they are able to do this 24/7.
  • California scientists are collecting specimens from 2,000 people to test for the presence toxins used in used in industry, agriculture and the home. They’ll use this information to explore such things as the connection between exposure and diseases, and to examine changes in exposure over time and the connection to changing health policies and industry regulations working to reduce exposure. [More on the work in California]
- Public health laboratorians test water samples in flood-ravaged areas to ensure that the water is safe to drink.
  • In 2008, severe flooding in Mason City, Iowa caused the closure of the water treatment facility. Residents were advised to boil their water until the system was restored and the water was tested to ensure it was safe to drink. The Hygienic Lab rose to the task and tested the water quickly bringing the treatment operation back online. [More on the floods in Iowa]
We would like to thank our unsung heroes in lab coats for protecting the public’s health – every day.

Salmonella Outbreak Leads to Heightened Surveillance

As laboratory and epidemiology surveillance systems expand and improve, more foodborne outbreaks are being detected. Additionally, the vehicles responsible have become more diverse. Whereas the classic “church supper” and other point source outbreaks once made headlines, now fresh produce, peanut butter, veggie snacks and even reptiles have been implicated in localized and complex multi-state outbreaks.

New culprits, including ingredients that were overlooked years ago, are now being detected as the source of food contamination. In the past few weeks, public health officials have heightened surveillance for Salmonella in the wake of the recalls of hydrolyzed vegetable protein or HVP. HVP is a flavoring additive that has been widely used in the food industry. It is sometimes referred to on packaging as “natural flavors.” This additive is found in thousands of products ranging from snack foods, ready-to-eat products (hot dogs, for example) soups, sauces and other processed foods. This recall may be the largest to date. (List of recalled foods.) Although no human illness has been associated with the recalls to date, the implicated strain of Salmonella was found at a food flavoring processing plant in Nevada.

APHL continues to support member laboratories on foodborne surveillance networks such as PulseNet. This laboratory-based surveillance system detects clusters of foodborne illnesses by using DNA fingerprinting technology. APHL supports member laboratories in the PulseNet network to improve surveillance though trainings, technical meetings, information dissemination, and grants.

This recall demonstrates the critical importance of the public health laboratory system and the need for maintaining and expanding food safety surveillance networks. By catching contamination more quickly, labs are able to prevent widespread outbreaks of foodborne illnesses; another important way that public health laboratories are keeping you healthy.
