Here ’s How Long You Can Safely Keep Eating Your Thanksgiving Leftovers

For those of us wondering how long we can get away with picking at our Thanksgiving leftovers, the United States government is here to help. This Thanksgiving season, the government is offering recommendations on how to safely store and consume your holiday leftovers. The food storage tips, which include such insights as a recommendation to refrigerate leftovers within 2 hours, were issued by FoodSafety.gov, an online portal to food safety information collected by Federal agencies like the The Food Safety and Inspection Service (FSIS) of the U.S. Department of Agriculture and the U.S. Food and Drug Administration (FDA). The information also includes a directive not to store stuffing inside a turkey, to avoid eating leftovers more than three or four days old, and to keep leftovers in a cooler with ice or frozen gel packs “if the food is traveling home with a guest who lives more than two hours away.” The site also recommends only storing food in shallow containers to decrease cooling time in the refrigerator and limit the amount of time your food spends at warmer unsafe temperatures. The guidelines, which come alongside instructions for safely preparing a turkey, may be especially helpful in the wake of a series of holiday season food safety issues. Earlier this week, the CDC warned U.S. consumers to not eat romaine lettuce, which could be contaminated with E. coli. 32 people in 11 states have been infected in the outbreak, including 13 who have been hospitalized...

This study aimed at investigating the influence of two key parameters (concentration of curcumin and illumination time) on the effects of curcumin-based photodynamic sterilization on the preservation of fresh-cut Hami melons. The results indicated that illumination with 50 μmol/L curcumin for 60 min using a blue LED lamp reduced the total aerobic microorganism count by ~1.8 log CFU/g in fresh-cut Hami melons. Besides this, the effects of photodynamic sterilization on the soluble solids content, color, water content, firmness, and sensory indices of the fresh-cut Hami melons were also evaluated. Compared to the contr...

Abstract Fresh vegetables are important components of an everyday balanced diet making ready to-eat-salads (RTE) a commodity widely consumed. However, in the past few years these products have been linked with outbreaks of salmonellosis and listeriosis; thus the continuous investigation of their safety is an essential requirement. A total of 216 samples of ready-to-eat salads from the Cypriot market were analysed to determine the microbiological quality and safety, along with physicochemical attributes of the salads and identify possible correlations between them. The samples were randomly collected from four reta...

CONCLUSION: The occurrence of genetically similar diarrheagenic E. coli in both groups of children, likewise resistant to these agents, underscores the importance of establishing strategies for the prevention of outbreaks, especially among low-income households.

Effective control of foodborne pathogens on produce requires science-based validation of interventions and control strategies, which typically involves challenge studies with a set of bacterial strains representing the target pathogens or appropriate surrogates. In order to facilitate these types of studies, a produce-relevant strain collection was assembled to represent strains from produce outbreaks or pre-harvest environments, including L. monocytogenes (n=11), S. enterica (n=23), shiga-toxin producing E. coli (STEC) (n=13), and possible surrogate organisms (n=8); all strains were characterized by whole genome sequencin...

We describe a ceftriaxone-resistant Salmonella Typhi bacteraemia in a pregnant woman returning from a family visit in Pakistan. Whole genome sequencing confirmed similarity to a Pakistani outbreak clone. Pregnancy and unawareness of this outbreak delayed appropriate antibiotic therapy. Concurrently, we detected faecal carriage of a carbapenemase-producing Escherichia coli. Awareness of the ongoing outbreak should affect empiric treatment of typhoid fever and hygiene precautions in travellers returning from Pakistan. Meropenem may be warranted in severe cases.

In conclusion, the results improve our understanding on the characteristics of lncRNAs and mRNAs on regulating host immune response against C. perfringens type C infection, which will provide a reference for future research into exploring C. perfringens-related diseases in human. Introduction Clostridium perfringens (C. perfringens) is a Gram-positive anaerobic rod and ranks as the second most common bacteria that causes fulminant, fatal infectious and immune diseases (Scharff, 2012; Grass et al., 2013). These diseases are characterized by fever, pain, gas production, local edema, and severe tissue destruction, the...

Conclusion Since B. cereus group are highly similar in biochemical as well as genetic profiles, a new biomarker was developed for identifying and distinguishing B. thuringiensis from the closely related group. The performance of XRE was compared with cry2 gene and artificially contaminated samples were also tested. Compared with cry2, XRE gene was observed to be efficiently accurate in the identification of B. thuringiensis. Further, the developed real-time PCR using XRE successfully identified B. thuringiensis and it could be used to quantify cell numbers with the generated standard curve.
