Food Poisoning Symptoms: Warning Signs, UK Outbreaks and When to Seek Help

Published on February 24, 2026 by Millie Titus

Right, let’s be honest. Nobody wants to spend their February sitting on a cold bathroom floor. But if you’ve looked at the news recently, it feels like half the UK is doing exactly that. We’re currently in a proper mess. Between the “Cape Verde” bug coming back in suitcases and a massive scare over baby milk, the country is basically one big gastro ward right now. If you’re reading this while feeling like your stomach is being wrung out like a wet towel, you aren’t alone. But you need to know what you’re actually dealing with. There is a huge difference between “I ate a dodgy prawn” and a “get me to A&E” emergency.

The Holiday Hangover: The Cape Verde “Shigella” Outbreak

The biggest story right now involves people coming back from winter sun holidays. Since late last year and into February 2026, the UKHSA has been tracking a nasty spike in Shigella and Salmonella cases linked to the Cape Verde islands. Over 150 Brits have come home with more than just a tan. Look, this isn’t just a bit of a run-of-the-mill tummy ache. Shigella is aggressive. We’re talking about blood in the stool, high fevers, and cramps that make you want to curl into a ball. As reported in the latest UKHSA Travel Alerts, this bug is incredibly infectious. You only need a tiny amount of the bacteria to get hit. If you’ve just stepped off a plane from Boa Vista and you’re seeing red in the loo, don’t wait. Call your GP.

The Baby Formula Panic

The other thing causing a stir this month is the massive recall on infant formula. Nestlé (SMA) and Kendamil have had to pull batches off the shelves because of something called Bacillus cereus. This is a “toxin-producing” bacteria. The scary part is the cereulide toxin it makes. Unlike most bugs, this stuff is heat-resistant. So, even if you’re using boiling water to make up a bottle, the toxin stays alive. It causes “rapid-fire” vomiting in babies—sometimes within 30 minutes. So if your little one suddenly starts being sick after a feed, you should check those batch codes straight away, according to the Food Standards Agency (FSA).

Spotting the “Tell-Tale” Signs

The average person simply refers to everything as “food poisoning,” but the timing of your food poisoning symptoms actually tells the tale of what’s happening inside you.

  • The 30-Minute Reaction: If you feel ill within minutes, it is usually a harmless toxin, such as the one found in the recalled baby milk or rice that has been left out too long.
  • The 24-Hour Ache: This is most often Salmonella or Campylobacter. Expect the chills, sore muscles and that sensation like you’ve been hit by a bus.
  • The 3-Day Delay: this is when things become serious. It takes a few days for bugs like the E. coli or Shigella to set up shop in the gut. Those are the ones that do the most harm.

Norovirus is Making a Comeback

Anyway, it isn’t just food. Norovirus levels are about 37% higher than the five-year average this February. People are calling it “food poisoning,” but it’s actually the “winter vomiting bug.” Here is the thing: hand sanitiser does absolutely nothing to norovirus. It’s like throwing water at a house fire. You have to use soap and hot water. The UKHSA reports show it’s ripping through schools and care homes right now. If one person in your house gets it, the clock is ticking for the rest of you.

The Golden “48-Hour” Rule

Look, I know your boss wants you in the office and the kids have school, but if you’ve been sick, you have to stay home. In the UK, the rule is simple: 48 hours symptom-free. Why? Because you’re still shedding the virus or bacteria long after you feel better. If you go back to work the day after you stop being sick, you’re basically a walking biohazard. Be a decent person. Stay home. Drink your rehydration salts and wait it out.

The “I Feel Sick” Survival Checklist

Symptom What it Likely Means What to Do
Projectile Vomiting Likely Norovirus or Bacillus cereus toxin. Small sips of water. Don’t gulp.
Bloody Diarrhoea Shigella or E. coli (Serious). Call 111 or your GP immediately.
High Fever & Shaking Salmonella or Campylobacter infection. Rest and Paracetamol (if you can keep it down).
Sunken Eyes/No Pee Severe Dehydration. This is an emergency. Get to A&E.

FAQ

Can I eat a piece of toast?

Stick to the BRAT diet (Bananas, Rice, Applesauce, Toast). It’s boring, but your gut can handle it. Avoid dairy or anything spicy for at least three days.

Is the “Tesco fruit pot” recall still a thing?

Yeah, check the FSA website. There was a recent issue with grape and berry medleys. If you’ve got one in the fridge, bin it.

What if I’ve just come back from Cape Verde?

If you’re sick, mention the travel to your doctor. They need to test specifically for Shigella because it sometimes needs specific antibiotics that normal bugs don’t.

Can I take Imodium?

Honestly? Try not to. If your body is trying to get rid of a nasty bacteria, stopping the “flow” can sometimes keep the infection in your system longer. Only use it if you’re about to get on a plane or something equally desperate. Anyway, it’s a very miserable way to spend a week, isn’t it? Your best bet is to have bleach ready and take little sips.  So, have you really checked the batch numbers on that milk in the cupboard yet, or are you going to just take your chances?
