Lacticaseibacillus rhamnosus shows promise
We explored the potential of Lacticaseibacillus rhamnosus GG as a probiotic treatment against avian pathogenic E. coli (APEC) in chickens. Our study showed that this probiotic significantly reduced APEC colonization in the chickens' cecum and improved the balance of gut microbiota over a 24-hour period.
Through laboratory evaluations, we detected novel bioactive peptides in the probiotic's culture supernatants, which may contribute to its antibacterial properties. While the results are promising for poultry health, more research is needed to optimize its use in real farming conditions.

We investigated the effectiveness of a new bacteriocin, LSB1, derived from Lactobacillus plantarum, in combating Staphylococcus argenteus—a harmful bacteria linked to food poisoning. This bacteriocin showed strong antibacterial properties, significantly inhibiting both the growth of planktonic and biofilm forms of the bacteria. LSB1 demonstrated notable stability under various conditions and a relatively low minimum inhibitory concentration. While the study indicates promising potential for LSB1 as a natural food preservative, more research is needed to fully understand its applications in food safety.

We investigated how a specific strain of Lactococcus lactis can help prevent food poisoning caused by a common pathogen found in raw milk and cheese. Our results showed a significant decrease in pathogen levels—by around 3 log CFU/mL—within just six hours when this strain was present.
Even more promising, it reduced the production of staphylococcal enterotoxin A (SEA) by 79%. In cheeses made with Lactococcus lactis, SEA was never detected, while it was found in higher levels in cheeses made without this protective strain. This study clearly shows Lactococcus lactis's potential in enhancing food safety through biopreservation.

Reduced food intolerances
2 people found this helpful
Best probiotic I have taken. I have used many brands over the years, but this one really works for me. I have fewer food intolerances with it and believe it’s more effective as it is enteric coated, resisting stomach acid. I suffer from food poisoning due to IBS, and this has been very helpful.

We explored how Lactobacillus K5 could help mice fend off E. coli O157:H7 infections. In our study, we observed that treating the mice with K5 ahead of exposure reduced their symptoms and helped maintain a healthier gut environment.
The benefits included less inflammation and more diversity in gut bacteria compared to untreated mice. Additionally, K5 boosted beneficial substances that protect the gut. Overall, this study shows promise for K5 in developing probiotic treatments for foodborne illnesses.

We explored the effectiveness of a synbiotic treatment combining Bifidobacterium longum and xylo-oligosaccharides in fighting Campylobacter jejuni, a major cause of food poisoning. The treatment was administered either from day one or day fourteen of the chicks' lives.
Our findings showed that early supplementation led to a significant reduction in C. jejuni levels compared to later treatment. However, Bifidobacterium levels did not significantly differ among treatment groups. These results suggest that early synbiotic use alongside other safety measures could help improve poultry meat safety.

We aimed to see how a synbiotic mixture might help reduce Campylobacter jejuni, a harmful bacteria often found in poultry, which can cause food poisoning in humans. Through our research, we provided broiler chickens with a blend of prebiotics and a specific strain of Bifidobacterium longum.
After 14 days, we observed a significant reduction in C. jejuni levels in the feces of treated chickens. This suggests that such synbiotic treatments could be an effective strategy for enhancing poultry safety and reducing foodborne illnesses linked to poultry products.

LGR-1 shows potential against B. cereus
In our study, we examined how Lactobacillus rhamnosus GR-1 (LGR-1) could protect bovine mammary epithelial cells from the harmful effects of Bacillus cereus, a common foodborne pathogen. By pretreating cells with LGR-1, we found that it helped maintain tight junction integrity and lowered inflammatory responses triggered by B. cereus. This suggests that LGR-1 might serve as a probiotic alternative to antibiotics and could prevent mastitis in dairy cows, promoting better food safety overall. However, the results do not indicate any significant direct benefits for human food poisoning cases.

Lactococcus lactis can reduce S. aureus
We explored the impact of Lactococcus lactis on food poisoning caused by Staphylococcus aureus, a common culprit in dairy-related outbreaks. This study examined how L. lactis can reduce the activity of a key virulence factor, known as the agr system, which is responsible for toxin production.
By showcasing the bacterium's reducing properties, we discovered that it can effectively downregulate this system, even in the absence of certain other regulatory components. This suggests that L. lactis might be a promising tool in managing Staphylococcus aureus in food safety.
