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.

The Route to Safer Fresh Fruits and Vegetables
Although fruits and vegetables are one of the healthiest foods sources in our diet, we continue to have foodborne disease outbreaks of significance from produce, sometimes affecting large groups of people in multiple states because of their wide distribution. The CDC estimates that fresh produce now causes a huge number of foodborne illness outbreaks in the United States. Produce needs our continued food safety efforts at the restaurant level as well as at the stages in agricultural production. Occasionally, fresh fruits and vegetables can become contaminated with harmful bacteria or viruses, such as Salmonella, E. coli 0157:H7, Norovirus, and Hepatitis A. This contamination can occur at any point from the field to our table. If eaten, contaminated fruits and vegetables can cause foodborne illness.
Be Cool, Chill Out, Refrigerate Promptly!
The Cold Chain -- Keeping perishable foods at proper cold holding temperatures (between 28°F and 41°F maximum or 0°F for frozen food) from your food producers / manufacturers to your customers has to be one of our strongest links to safe food and high quality. Sometimes that is referred to in the food industry as “maintaining the COLD CHAIN”. Any slip ups in the cold chain, and we have a weak link. Most all of our state food regulations require 41°F as a cold maximum, but colder is a “best practice” policy to maintain.
Cutting Board Safety
Everyone knows to prepare food only on a clean and sanitized surface. Everyone also knows not to prepare food on a surface previously used to prepare any type of uncooked meat—cross-contamination. But does everyone know what this clean, sanitized, uncontaminated surface should be made out of? Or how cutting boards should be cared for?
A Date with Safe Food Labels
When it comes to food, calendar dates relating to time and temperature are important and sometimes confusing. Terms we use are: 1) food product or code dating used for commercial food manufacturing and 2) date marking used for food prepared onsite in a restaurant. In a restaurant at the receiving step or the retail food store as a consumer, "Sell by July 14" is a type of information you might find on a meat or poultry product. Are dates required on food products? Does it mean the product will be unsafe to use after that date? Here is some background information, which answers these and other questions about food product dating.
