Unhealthy diet? Food safety regulations need updating | TheHill – The Hill

While our nation has been focused on COVID-19, other public health problems have not disappeared. In particular, microorganisms transmitted by food continue to cause major public health problems in the United States.The bacteriasalmonellaandcampylobacterare of specific concern, accounting for over 70 percent of the foodborne illnesses tracked by the Centers for Disease Control and Preventions (CDC) Foodborne Diseases Active Surveillance Network.Thesetwo bacteria annually accountfor approximately 3 million illnesses in America and cost over 6 billion dollars.Chicken and turkey are among the most common foodborne sources for these bacteria.

As leading food safety scientists in the United States, we have spent our careers trying to fight this problem.Salmonellaandcampylobacterare so damaging to public health that reducing the number of these illnesses is included in the Health and Human Services Healthy People goals, national health goals set every 10 years.The number of people falling sick from these bacteria has not changed in 20 years, though, meaning the Healthy People 2020 illness reduction goals were not met and almost the exact same goals were included inHealthy People 2030goals established last year.

A primary reason for this lack of progress is the outdated food safety regulation of poultry products by the United States Department of Agriculture (USDA), which has not substantially changed since the 1990s. The regulation is based on science that lags behind what we know today.

The regulation approaches all types and amounts ofsalmonellaand campylobacter contamination the same.New evidence shows that somesalmonellatypes, such assalmonella Heidelberg, pose a much greater danger to human health than others, such as salmonella Kentucky, which causes very few human illnesses.New technology is also available to distinguish between these types ofSalmonellaand estimate the amount of bacterial contamination on products.Yet, under the current regulatory system, onesalmonellaKentucky organism in a 25-gram sample of chicken is treated the same as 1,000 multi-antibiotic resistantsalmonellaHeidelberg in the same size sample.The same holds true for finding one campylobacteror more dangerous amounts in a sample.USDAfoundsalmonellain 31 percent of ground chicken and 8 percent of chicken partsit sampled at slaughter plants in 2019.It did not consider thesalmonellastrain or whether the sample contained one or 1,000 bacteria in determining if action to protect consumers should be taken.

This system of treating all contamination the same establishes disincentives for controlling the most dangerous types ofsalmonella. AssalmonellaKentucky is the most common type ofsalmonellathat is found on poultry carcasses, resources are spent attempting to preventsalmonellaKentucky contamination and diverted from developing programs targetingsalmonellatypes that actually threaten public health.

Another key problem with current regulations is that they focus solely on the presence ofsalmonellaandcampylobactercontamination in slaughter plants and on poultry end products, drawing attention away from where the bacteria may be most effectively controlled: at the farm. Some European country regulators have already successfully focused on farms, where vaccination (available for somesalmonellatypes), hygiene, and other control practices can have an impact felt throughout the supply chain.Reducing contamination at the farm can also reduce the spread ofsalmonellato nearby water that could contaminate fields used to grow produce. In contrast, the end-product focus in the U.S. establishes incentives for companies to respond tosalmonellaand campylobacterprimarily with post-slaughter controls that allow them to meet the broad regulatory standards.

The changes needed are clear.Regulation at the USDA should better encourage reducing poultry contamination with the most dangerous bacteria at all stages of the supply chain and help prevent them from even entering slaughter plants. In addition, regulations should reduce contamination with thosesalmonellatypes which pose the most danger to the public rather than target allsalmonella and should include a focus on reducing the frequency of contamination with high levels of bacteria.Years of evidence indicate that the current regulations do not work as well as they should to protect public health. Trying to meet the 2030illness reductiongoals with the same regulations and policies that already failed makes no sense.

COVID-19 made clear that there are many weaknesses in our public health system that should have been addressed before the pandemic. We know that our food safety system is antiquated; now is the time for regulatory changes.Lets modernize our regulatory approach, using up-to-date science, to truly build an effective and efficient national food safety system.
