We set out to explore how zinc oxide nanoparticles (ZnO NPs) could help control the bacteria responsible for food poisoning in raw chicken meat. Our approach involved integrating these nanoparticles into packaging materials to see if they could effectively inactivate Campylobacter jejuni, a common and concerning pathogen in poultry.
Through our experiments, we discovered that immobilizing ZnO NPs in functional pads placed under raw chicken could dramatically reduce bacterial counts. In fact, we saw a reduction from about 4 log CFU to an undetectable level within just three days when storing chicken at 4°C. Notably, we monitored zinc levels in the chicken meat, confirming a safe release of zinc without any migration of nanoparticles onto the food. This means that we can help keep raw chicken safe and fresh without compromising its integrity or quality.
Not only did we find that these functional pads inactivated the harmful bacteria, but we also noted a related increase in lactic acid production, which plays a role in further protecting the meat. Our findings open up new avenues for using zinc in food packaging, offering a way to enhance food safety without directly adding chemicals to the food itself. Overall, this study highlights the potential for nanotechnology to play a significant role in managing foodborne pathogens like Campylobacter in poultry products.

Zinc composites combat foodborne pathogens
We explored how green-synthesized cellulose nanocrystal and zinc oxide (ZnO) bio-nanocomposites could help in battling food poisoning caused by harmful bacteria. By using natural resources like palm sheath fibers, we created these nanocomposites without harsh chemicals, making the process sustainable.
Our team tested the effectiveness of these bio-nanocomposites against major foodborne pathogens such as E. coli, Salmonella, Listeria monocytogenes, and Staphylococcus aureus. We observed that the CN-ZnO nanocomposites were effective at inhibiting bacterial growth, showcasing their potential as natural preservatives in food systems.
Moreover, we found that these composites not only killed bacteria but also significantly reduced the expression of virulence toxin genes in the bacteria we studied. This decrease in toxin production means that not only do we reduce the bacteria, but we also lower the risk of food poisoning, making these nanocomposites a promising tool for food safety.
In conclusion, our results suggest that cellulose nanocrystal-based ZnO nanocomposites could provide a dual action by preventing microbial growth and curtailing the harmful effects of bacterial toxins, which is a crucial step in protecting public health against foodborne illnesses.

Zinc nanoparticle toxicity effects
In our research, we investigated how zinc oxide nanoparticles (ZnO-NPs) affect food poisoning, particularly focusing on their toxicity in Common carp. We carried out a thorough study involving 540 fish, which were divided into 18 groups and fed different diets over 30 days. Among these diets were options containing varying concentrations of ZnO-NPs, alongside a beneficial plant extract called Allium hirtifolium, known to enhance health and antioxidant levels.
The results were telling. Diets with ZnO-NPs generally raised stress levels and disturbed the balance of essential blood and biochemical markers in the fish. However, when we supplemented the diets with Allium hirtifolium extract, we observed significant improvements in antioxidant parameters. Specifically, the fish receiving this extract demonstrated enhanced antioxidant activity, evidenced by lower levels of harmful substances and higher activity of protective enzymes.
Importantly, the extract appeared to mitigate the negative impacts of ZnO-NPs, suggesting potential protective effects. Yet, we noted no significant differences in some antioxidant markers when we compared AHE-supplemented diets against those solely containing ZnO-NPs. This indicates that while zinc does have harmful effects, the role of AHE in combating these effects is noteworthy, though not universally significant across all measures.
