Interventions in food business organisations to improve food safety culture: a rapid evidence assessment.

The European Commission recently adopted Commission Regulation (EU) 2021/382 requiring food businesses to establish and provide evidence of a food safety culture (FSC). FSC incorporates management systems, risk perceptions, leadership, communication, environment and commitment to ensure food safety. This review ( = 20) investigates food safety interventions in food businesses to identify effective strategies to improve food safety practices and FSC, and to provide recommendations for improving FSC.

Solid-state (2)H NMR and MD simulations of positional isomers of a monounsaturated phospholipid membrane: structural implications of double bond location.

The impact that the position of double bonds has upon the properties of membranes is investigated using solid-state (2)H NMR and MD simulations to compare positional isomers of 1-palmitoyl-2-octadecenoylphosphatidylcholine (16:0-18:1PC) bilayers that are otherwise identical apart from the location of a single cis double bond at the Delta(6), Delta(9), Delta(12), or Delta(15) position in the 18:1 sn-2 chain. Moment analysis of (2)H NMR spectra recorded for isomers perdeuterated in the 16:0 sn-1 chain reveals that average order parameters S(CD) change by more than 35% and that the temperature for chain melting T(m) varies by 40 degrees C. At equal temperature, the S(CD) values exhibit a minimum, as do T(m) values, when the double bond is in the middle of the 18:1 sn-2 chain and increase as it is shifted toward each end.

Location and assessment of an historic (150-160 years old) mass grave using geographic and ground penetrating radar investigation, NW Ireland.

Reburial of human remains and concerns regarding pathogens and pollution prompted the search for, and assessment of, a 156-year-old graveyard. To locate this graveyard, historic and anecdotal information was compared to landscape interpretation from aerial photography. To assess and map the contents, surface collapses, metal detector indications, and ground-penetrating radar (GPR) were used.
