New Zealand- Cheeses recalled due to possible presence of E. coli

MPI

New Zealand Food Safety is supporting Waimata Cheese Company Limited in its recall of a specific batch of its Camembert and Brie Cheeses due to the possible presence of E. coli.

The following products with batch number 8367 and a best before date of 28/02/24 are affected by this recall:

  • Waimata Cheese brand Camembert
  • Longbush Camembert
  • Longbush Brie.

Up-to-date details of products affected by the recall, including photographs, are available on our food recall page.

“The concern with these cheeses is that there may be E. coli bacteria present,” says New Zealand Food Safety’s acting deputy director general Jenny Bishop.

“Symptoms of sickness caused by E. coli include stomach cramps and diarrhoea. Some people feel sick and vomit.

“Most people get better within 5 to 7 days, but the effects can be serious for people with weakened immune systems, including the very young, frail older people, people with weakened immune systems and pregnant people.

E. coli can travel easily and fast from person to person if infected people do not wash their hands properly.

“If you have consumed any of this product and are concerned for your health, contact your health professional, or call Healthline on 0800 61 11 16.

“Affected product should not be eaten. It can be returned to the place of purchase for a refund. Should you be unable to do this, throw it out.”

The recalled products are being removed from shelves at stores nationwide.

E. coli was discovered as a result of routine testing. New Zealand Food Safety has not received any notification of associated illness.

“As is our usual practice, New Zealand Food Safety will be working with Waimata Cheese Company Limited to understand how the contamination occurred and prevent its recurrence,” Ms Bishop said.

For further information and general enquiries, call Ministry for Primary Industries (MPI) on 0800 00 83 33 or email info@mpi.govt.nz

Research – Tomato juice’s antimicrobial properties can kill Salmonella

Science Daily

Tomato juice can kill Salmonella Typhi and other bacteria that can harm people’s digestive and urinary tract health, according to research published this week in Microbiology Spectrum, a journal of the American Society for Microbiology. Salmonella Typhi is a deadly human-specific pathogen that causes typhoid fever.

“Our main goal in this study was to find out if tomato and tomato juice can kill enteric pathogens, including Salmonella Typhi, and if so, what qualities they have that make them work,” said principal study investigator Jeongmin Song, Ph.D., Associate Professor, Department of Microbiology & Immunology, Cornell University.

Research – The Investigation of Changes in Bacterial Community of Pasteurized Milk during Cold Storage

MDPI

Abstract

The quality of pasteurized milk is commonly assessed through microbiological analysis, with variations in storage conditions significantly impacting the suppression of bacterial growth throughout the milk’s shelf life. This study investigated the dynamics of total bacterial counts (TBCs) and bacterial community shifts in milk that underwent pasteurization at 80 °C for 15 s. The milk was subsequently stored at 4 °C for varying intervals of 1, 4, 7, 10, 13, and 16 days. Culture-based testing revealed a significant TBC increase during the storage period spanning 1 to 16 days (up to −log10 4.2 CFU/mL at day 16). The TBC in pasteurized milk exhibited accelerated microbial growth from day 13 onwards, ultimately peaking on day 16. Bacillus was detected through 16S rRNA identification. Principal component analysis demonstrated a significant impact of storage time on bacterial communities in pasteurized milk. Analysis of bacterial diversity revealed a negative correlation between the Shannon index and the duration of pasteurized milk storage. Using high-throughput sequencing, Streptococcus and Acinetobacter were detected as prevalent bacterial genera, with Streptococcus dysgalactiae and Streptococcus uberis showing as dominant taxa. The presence of Streptococcus dysgalactiae and Streptococcus uberis in pasteurized milk might be attributed to the initial contamination from raw milk with mastitis. This study offers new evidence of the prevalence of bacterial community in pasteurized milk, thereby adding value to the enhancement of quality control and the development of strategies for reducing microbial risks.
