One year ago, community transmission of COVID-19 in the United States led several states to impose stay-at-home orders to reduce person-to-person transmission of the virus. As the year went on, messaging on hand hygiene, mask wearing, and social distancing were stressed as public health measures that were our best tools for combatting COVID-19. While the measures used to prevent the spread of COVID-19 varied from state to state, the COVID-19 pandemic disrupted life as we knew it and changed the way we have been living our daily lives since then. Early on, there was speculation that these newly emphasized public health measures would reduce the spread of other diseases as well. Hand washing had always been recommended but not always followed. One year since the COVID-19 pandemic began, we now have the data to begin looking at how the reaction to the pandemic impacted the spread of other communicable diseases.
As many public health officials predicted, there has been an impact on rates of other respiratory diseases. The CDC has noted that flu activity is significantly down this flu season, compared to the previous flu seasons.1 This decrease in seasonal flu is hypothesized to be due to a combination of the improved public health measures as well as an increase in vaccinations compared to previous flu seasons. The increase in vaccinations could have been driven by a strong campaign to encourage vaccination.2 Two studies have also found that social distancing and travel restrictions have decreased other non-COVID hospital admissions as well.3 4 The first found a significant decrease in non-COVID-19 respiratory diseases and the second actually found a decrease in foodborne and sexually transmitted diseases. However, there is also evidence that the pandemic has reduced the number of people seeking healthcare as they want to avoid potential exposures in the clinics and hospitals.5 So while the decrease we see in some non-COVID illnesses may be due to the positive impact of social distancing and mask wearing, it may also be because people that have those illnesses are no longer seeking care, and so are not captured in the statistics.
So how does foodborne disease fit into all of this? Initially, the CDC had noticed that last summer, the expected counts from PulseNet, an active foodborne disease outbreak surveillance system, were lower than previous years. The question was whether this was due to improved hand hygiene and a rise in contactless delivery, or whether people with foodborne diseases were less likely to seek care during the pandemic.
At CFI, we are currently working with Ohio State’s Information Warehouse Database (IWD) of electronic health record data as part of a new project. This database contains health information for all adults seen within the OSU healthcare system. While we are primarily using the data to look at the impact of long-term health outcomes from an incident case of foodborne disease, we can also use the data to determine whether there is a true decrease in cases during the pandemic or whether it is due to a drop in healthcare-seeking behavior. The work done on this project should help clarify what is happening with foodborne disease during the pandemic.

With the continuation of social distancing and stay-at-home orders, individuals are cooking at home more often than they may have in the past. While this cooking increase can lead to healthier meals, proper food safety must be followed to kill any potential foodborne pathogens. Although many people own a food thermometer, many people do not know how to use them properly. When cooking meat or eggs, a food thermometer is an essential kitchen item in preventing foodborne illness.
While all food thermometers are capable of reading temperatures, they are not created equal. Even though all thermometers can register temperature, each does it in different ways, making different types of thermometers appropriate for different uses.
Though not an exhaustive list, the chart below gives additional information on some thermometer types commonly used in the home kitchen. While no one individual needs all these thermometers, cooks should use this knowledge to help guide the thermometer they choose to ensure it is appropriate for their regular needs. All thermometers included in chart can be found with relative ease either in store or online.
|Thermocouple||2-5 sec.||Can be inserted as little as ¼” or deeper as needed||
Can be used for both thick (>1/2”) and thin foods
Should not be left in food while cooking
Can be expensive
|Thermistors||10 sec.||At least ½” deep in the food||
Can be used for thick and thin foodsUsed to check food temps at end of cooking time
|Oven Cord Thermometers||10 sec.||At least ½” deep in the food||
Can also be used outside the ovenCan remain in food while cooking
|Thermometer Fork Combination||10 sec.||At least ½” deep in the food||Used to check food temps at the end of cooking time|
|Pop-Up Timers||Reacts when meat is 1 to 2 degrees F from ideal temperature||Thickest part of meat||
Recommend verifying temperature with conventional food thermometer.Accuracy highly dependent on proper placement
|Liquid-Filled Thermometers||10 sec.||At least 2 inches deep||
Can get false high readingsNot good for food safety purposes
|Candy/Jelly/ Deep Fry Thermometers||10 sec.||Sits in pan with tip in liquid||
Can be used for candy making and fryingCan measure extra-high temperatures
Armed with the knowledge of what thermometer to choose, home chefs must also remember some these important tips to ensure the safe use of their chosen thermometer:
- Check manufacturer’s instructions to ensure you are following proper instructions.
- For roasts, the thermometer should be inserted midway into the thickest part of the meat, away from the bone.
- For burgers, steaks, and chops the thermometer should be inserted into thickest part away from bone, fat, and gristle.
- Poultry should be measured at the innermost part of the wing or thigh, and in breasts it should be in the thickest part.
- Be sure to use caution when checking food temperature.
- Remove food from heat.
- Make sure to wear hand covering/ oven mitts when handling metal probes.
