Changing Climate: The Unseen Impact on Food Safety

In June, I was asked to participate in the Allinfoodz podcast, put on by a colleague, Dr. Amit Sharma, at Penn State University.  One of the points Dr. Sharma wanted to discuss was the impact of climate change on food safety, which is something I was certainly aware of, but not something I had done much research on.  However, when preparing for the interview and podcast, it was interesting to learn more about the relationship between the two.

Although the topic of climate change can be a political hot button in an age where everything seems to be to the extremes, regardless of the cause, there is evidence weather patterns across the globe are changing, and this change does have an impact on overall food safety in the complex global food system.  One thing we can all agree on is climate change and food safety impact all of us.

It shouldn’t be difficult to understand the impact rising temperatures could have on food safety, and I am guessing anyone who reads these blogs has likely taken a food safety training class and understands the temperature danger zone – the range from 41°F to 135°F where bacteria multiple the fastest.  Thus, it stands to reason that the warmer our environment becomes, the greater the chances for a foodborne illness outbreak.  A few years ago, the World Health Organization released a report that noted when the ambient temperatures are greater than 41°F, cases of salmonellosis in Europe would increase 5% to 10% for each 1.8°F increase in the average weekly temperature.  Several different studies have noted very similar results in various countries and cities around the world.


…the warmer our environment becomes, the greater the chances for a foodborne illness outbreak….cases of salmonellosis increase 5% to 10% for each 1.8°F increase in weekly temperature average. 


As temperatures increase, extreme weather events are more likely to occur. Just last month, we had six extreme weather events occur in the US on the same day, June 13. While Yellowstone National Park was dealing with flooding that closed the park, the Midwest and Southern part of the US were hit by a derecho, while other parts of the Midwest and South dealt with a severe heat wave, wildfires raged through Alaska and the Southwest, and the west was still in the midst of a drought.

What does this mean for the foodservice operation?  Be vigilant. Changing weather patterns will increase the incidence of foodborne illnesses over time. Bacteria, viruses, and parasites will mutate and change, new concerns will emerge. Stay up to date with these issues to have the best chance at protecting your business and your customers.

I do hope you all had a happy and safe 4th of July.

A Little Poultry Safety Information

Chicken is the number one species of protein consumed by Americans – we eat about 80 pounds of it per year. Outbreaks of foodborne illness have long been associated with poultry and eggs usually by undercooking it or cross-contamination of other foods by raw poultry. Recent concerns about avian or bird flu put the direct focus on our fowl food with concerns about whether this awful disease can transfer from birds to humans.

The Basic Principles of Food Safety

Every food establishment uses, processes, and sells food in different ways. However, the general issues and key principles of food safety remain the same, whatever the style of the operation. All food safety training programs should contain the “big 3” factors that could cause food to become unsafe. Food must be kept out of harms way from human errors, but if you don’t train food workers what they are, they won’t know why these factors are so important to your operation. The basics can make us or break us in one or maybe two food handling mistakes.

Be Aware When You Prepare – Food Prep Tips

The subject of food preparation covers some very broad, basic principles within food safety, with many steps associated with “risk” in some recipes. Certainly, preparation steps are where the most mistakes have occurred if a foodborne illness should occur. Outbreaks usually happen when more than one mistake occurs during prep, but sometimes it only takes one. Cooking is the biggest risk for raw foods, but all foods become ready-to-eat foods at some point in final preparation steps and that’s where the most care is required.

Food Gloves & Latex Allergy Education

Politicians joke about the endless stretch of rubber chicken dinners they may consume in an election year. For people with a latex allergy, such a prospect may be no laughing matter. While latex serves as an effective barrier glove material and has the best fit because of its elasticity, the risks associated should not be ignored. The solution is not simple and many options are available for operators today. It should always be mentioned that handwashing (before putting on gloves) is always the primary barrier to contamination and gloves are considered a good secondary barrier.
