Ice Cream and Food Poisoning: Can Refreezing Thawed Frozen Food?

 

In the quest to beat the summer heat, many people seek the refreshing indulgence of ice cream or milkshakes. However, while the risk of an upset stomach is acknowledged during the enjoyment of cool treats, the potential danger of food poisoning is sometimes overlooked. The culprit behind such food poisoning is the 'Listeria bacterium' known for its ability to survive and proliferate even in low temperatures.

 

 

Measures to Prevent Food Poisoning

For those mindful of their health, it is crucial to store and consume ice cream in the right conditions. Infectious disease specialists advise, "If ice cream is not stored in the proper conditions, bacteria can multiply, and consuming contaminated ice cream can lead to food poisoning. Especially when ice cream melts and is refrozen, altering its texture, it is advisable not to consume it." Such alterations can promote bacterial growth.

 

U.S. Case and Severity of Food Poisoning

In Washington state, there has been a case where three people died and three were hospitalized after consuming milkshakes sold at a hamburger franchise. Listeria bacteria were detected in the milkshakes, confirming food poisoning caused by this bacterium. Instances like these underscore the severity of food poisoning.

 

Characteristics and Prevention of Listeria Bacteria

Listeria bacteria have a robust survival ability even at temperatures as low as -18 degrees Celsius. Moreover, it has a long incubation period, with symptoms possibly not appearing immediately after infection. Commonly found in meat and dairy products, Listeria can lead to severe illnesses in individuals with weakened immune systems or the elderly. According to the U.S. Centers for Disease Control and Prevention (CDC), an average of 1600 people become infected with Listeria each year, resulting in 260 deaths.

 

Guidelines for Preventing Food Poisoning

To prevent food poisoning, it is essential to handle and store food safely. Situations like thawing and refreezing can trigger bacterial growth. Therefore, it is advisable to avoid consuming products that have been △thawed and refrozen, △altered in appearance, or △have an extended shelf life. Additionally, storing food at the right temperature and in the proper environment, and scooping ice cream from a large container when consuming can contribute to safer food practices.

 

Conclusion

To prevent food poisoning, cultivating habits of safely handling food is crucial. It's not just an issue limited to ice cream; the practice of thawing and refreezing frozen products is risky. Rather than hesitating to discard, it is important to boldly dispose of items that might pose a risk when consumed.
