Research – Inhibition and eradication of Listeria monocytogenes biofilm using the combined treatment with nisin and sesamol

Science Direct

Abstract

Listeria monocytogenes can form biofilms, which enables it to persist in the food industry and poses a significant threat to food safety. The combination of nisin (NS) and sesamol (SE) has been found to inhibit the proliferation of L. monocytogenes. The objective of this study is to evaluate the effects of the combined use of NS and SE on the biofilm formation of L. monocytogenes and investigate the potential underlying mechanisms. The results showed that the combination of NS and SE completely inhibited the biofilm formation of both strains on the stainless steel sheet within 48 h. The existing L. monocytogenes biofilm on the stainless steel sheet was completely removed within 4 h after the combined treatment of NS and SE. Compared with individual treatment, the combined use of NS and SE resulted in a more significant downregulation in gene expression of fbpA, which is associated with L. monocytogenes biofilm formation. The findings suggest that the combined strategy of NS and SE in food processing has greater potential to control the formation of L. monocytogenes biofilms and eliminate existing ones, compared with using NS or SE alone.

New Zealand – Our Fruit Box or OFB raw fruit juice recalled due to potential food safety risks

MPI

New Zealand Food Safety is directing a recall of all raw fruit juice from Our Fruit Box or OFB and is advising people not to consume the product.

“This raw fruit juice presents a food safety risk because it has not been through the required checks and balances to make sure it is safe to consume,” says New Zealand Food Safety’s deputy director-general Vincent Arbuckle.

“The company making these juices has not been registered under the Food Act, so consumers cannot be certain that risks have been properly identified and managed.

“The product is a raw fruit juice and for that reason food safety controls are crucial. Without proper controls during processing of food, pathogens can enter the product.

“Pathogens such as Shiga toxin-producing E. coli (STEC), SalmonellaCryptosporidium and norovirus can be present in the juice, making it unsafe to consume, particularly for people who are young, older, pregnant or with weakened immune systems.”

The recalled raw juice has limited identifying labelling or branding and may be sold in 20 litre plastic containers labelled ‘OFB’ and in unlabelled bottles of different shapes and sizes.

Available information suggests the raw fruit juice has been available for sale through informal sellers, door-to-door through businesses, local markets and online on their website.

OFB – Our Fruit Box 

“If you have bought this product – either labelled OFB or Our Fruit Box, or with limited or no identifying labelling or branding – do not consume it and throw it out,” says Mr Arbuckle.

“If you are unsure of whether an unlabelled product you have bought is OFB, ask the supplier.”
