A close-up image of gloved hands drawing liquid from a small glass vial into a syringe. The background is blurred in pale blue tones. Yellow text on the left reads: “Could ‘fridge‑free’ vaccines transform global immunisation?” A yellow label in the top right corner displays the URL “ukhsa.blog.gov.uk”.

Cold chain failures mean that half of all vaccines don't reach the people who need them.

A new clinical trial supported by UKHSA could help change that.

Gauri Godbole, Deputy Director, Gastrointestinal Infections, Food Safety and One Health at UKHSA, said:
'Raw pet food products can carry harmful bacteria such as Salmonella and Campylobacter, which can cause diarrhoea, stomach cramps and sometimes vomiting and fever.
To reduce the risk of illness, pet owners should wash their hands thoroughly after handling raw pet food, clean and disinfect bowls, utensils and surfaces, store raw pet food separately from food for people and ensure good hygienic practices for handling of pet faeces.'

The Food Standards Agency (@foodgov.bsky.social) is reminding people to take care when handling raw pet food, following a survey that found some products can contain harmful bacteria that could make pets and their owners ill.

Dr Gauri Godbole
Deputy Director for Gastrointestinal Infections, Food Safety and One Health at UKHSA, said:
“February is a popular time for winter sun holidays and we want to help families make the most of their breaks by staying healthy.
The best way to avoid gastrointestinal infections, including Shigella and Salmonella, or passing them to others, is simply by washing your hands regularly and thoroughly with soap and water or alcohol gel – particularly after using the toilet, changing nappies, and before eating or preparing food.”

📰🆕 Our latest data shows cases of Shigella and Salmonella linked to travel to Cape Verde, a popular winter sun destination. As many UK residents prepare for half-term holidays, we share advice on how to avoid gastrointestinal infections.

Gauri Godbole
Deputy Director, Gastrointestinal Infections at UKHSA, said:
“We’re investigating a number of Shigella cases in the UK. Most people affected had travelled to Cape Verde, mainly staying at hotels in the Santa Maria and Boa Vista areas.
Shigella can cause watery and bloody diarrhoea, stomach cramps and fever. It can be caught from contaminated food or water, often linked to overseas travel, but can also be transmitted during and after sex.”

We are current investigating Shigella cases linked to travel to Cape Verde. Regular handwashing with soap and water (especially after the toilet, changing nappies, and before handling food) is the best way to prevent the bacteria from spreading.
