Title: Employing Ultrasound Tech for Safer Spinach Consumption
🤓 Hey there, fitness and health enthusiasts! This week, we've got some exciting news for you. University of Illinois professor, Hao Feng, has found a game-changer for green smoothie lovers. By combining continuous ultrasound treatment and chlorine, he's managed to get rid of an astounding 99.99% of E. coli bacteria in spinach! 🥬
Why This Matters
Spinach has always been a superfood darling, owing to its nutritional benefits. However, it's not exactly been immune to public health controversies. Between 1999 and 2009, greens like spinach were responsible for 24% of food-related E. coli outbreaks! And guess where spinach frequently tops the list? The Food and Drug Administration's Riskiest Foods!
Contamination can occur through contact with animal waste, infected irrigation or picking equipment, or even improperly fertilized soil. Spinach's leafy structure and preference for raw consumption make it particularly susceptible to these contaminants.
Currently, rinsing leaves with a chlorine solution is the standard pre-market cleaning method. While it effectively kills between 90-99% of bacteria, some sneaky bacteria can still survive and cause health issues, especially for individuals with weakened immune systems, children, and the elderly.
Professor Feng's new cleaning technology might just be the silver lining to this spinach conundrum.
The new cleaning technology: Ultrasound waves and chlorine
Ultrasound waves might sound like a sci-fi gadget, but they're nothing new. They're simply high-frequency sound waves that humans can't hear. These waves have been widely used in medical diagnostics. Interestingly enough, they're also perfect for decontaminating food products like apple juice... and now, spinach!
But wait, there's more! Feng's super-sanitizer resembles a large spinach tub with a few unique features. He added jets to keep the leaves consistently moving in the tank and evenly exposed to the chlorine solution and ultrasound waves. Large ultrasound transducers distributed the waves evenly, ensuring each leaf got equal treatment. By treating all leaves equally, Feng eliminated any risk of cross-contamination.
Can We Trust It?
Right now, Feng's super-sanitizer is still in the trial phase, so we can't expect it on grocery shelves anytime soon. Still, we're all rooting for this technology to make its way into the mainstream. If it does, we can enjoy more nutritious and, most importantly, safer spinach!

Enrichment Data
Overall:
The article doesn't provide a direct answer on the effectiveness of Hao Feng's method of using ultrasound treatment and chlorine to reduce E. coli bacteria in spinach. However, ultrasound and chlorine are commonly used separately to decontaminate food and water. Research indicates that combining these methods might enhance bacteria reduction due to ultrasound's physical disruption of bacterial cells, making them more susceptible to chlorine's disinfectant properties.
However, for specific results related to spinach and E. coli, you should consult scientific studies or research papers examining this combination in that context. The article adds some curiosity around this idea but lacks detailed information.
This discovery by Professor Hao Feng could significantly improve the nutrition and safety of green smoothies, as spinach is a key ingredient. Spinach, often associated with nutritional benefits, has been a concern due to E. coli outbreaks linked to its consumption.By using ultrasound waves and chlorine, Professor Feng's method has shown promising results in reducing up to 99.99% of E. coli bacteria, addressing a public health issue associated with other nutrition sources like vegetables.
