There is a very simple question that most of us probably never ask when buying a box of eggs.
Where did these eggs actually come from?.
We look at the price. We look at the number of eggs in the box. Perhaps we look for free-range or organic.
But how many of us turn the box over and look for the British Lion mark?
The question has suddenly become rather more important.
Britain is currently dealing with a significant Salmonella outbreak involving 207 confirmed cases, one death and at least 34 hospitalisations. Six of the cases have been identified in Scotland.
The UK Health Security Agency says the outbreak may be linked to eggs imported from outside the UK, particularly eggs being used by restaurants, cafés and other catering businesses.
At the same time, the authorities have stressed that there is currently no identified link to UK-produced eggs or poultry.
That distinction is crucial.
This isn't a story about saying that foreign eggs are dangerous and British eggs are automatically safe.
It is a story about traceability and assurance.
And when you start looking at what Britain's major supermarkets actually sell, an interesting picture emerges.
Lidl: 100% British shell eggs
Let's start with Lidl.
Lidl GB makes a remarkably clear statement about its shell eggs.
It says:
"Our shell eggs are 100% British and assured to the British Lion standard."
That is quite reassuring information for shoppers.
It means that if you are buying fresh shell eggs from Lidl, the supermarket says they are sourced from British suppliers and covered by the British Lion assurance system.
This isn't a minor detail.
The Lion scheme includes specific food-safety controls, including Salmonella vaccination and traceability.
So, despite all the headlines about imported eggs, Lidl's current policy on fresh shell eggs is very straightforward.
British eggs. British suppliers. British Lion assurance.
Of course, supermarket sourcing can change and individual products should always be checked, but Lidl is unusually clear about its position.
Tesco: look at the box
Tesco is also selling British Lion eggs.
Take some of its current own-brand ranges.
Its British Barn Eggs carry the Lion mark and are described as quality eggs laid by British hens vaccinated against Salmonella.
Its large free-range eggs are also listed as produced in the UK, with the Lion mark described as the guarantee that the eggs are from British hens vaccinated against Salmonella.
And Tesco's British Mixed Weight Eggs similarly carry the Lion assurance.
So Tesco provides another useful lesson.
You don't necessarily have to know which individual farm produced your eggs.
The information on the packaging can tell you something important about the production system behind them.
What exactly does the Lion mark mean?
This is where the little red Lion symbol becomes much more significant.
The British Lion scheme isn't simply a branding exercise.
The Food Standards Agency has previously assessed eggs produced under the Lion Code, and demonstrably equivalent schemes such as Laid in Britain, as presenting a very low risk to UK consumers.
The scheme includes measures designed specifically to control Salmonella.
Among them are:
Salmonella vaccination of laying hens.
Testing and monitoring.
Traceability through the production chain.
Controls covering feed.
Hygiene requirements.
Independent auditing.
The British Lion website itself says the mark indicates that the hens have been vaccinated against Salmonella and that the eggs have been produced under its food-safety standards.
The result is that the Food Standards Agency permits certain vulnerable groups to eat runny or raw eggs when they carry the Lion mark or are produced under the Laid in Britain scheme.
That is a fairly powerful endorsement.
But then comes the interesting question
If Lidl and Tesco can tell us where their shell eggs come from, why is the current outbreak apparently associated with eggs used by catering businesses?
This is where the story becomes more complicated.
The UKHSA says its investigation has identified five food businesses where two or more people who became ill had eaten during the week before their symptoms developed.
Those businesses were supplied with eggs from multiple sources, including egg importers.
Investigators have also identified possible cross-contamination risks at two of the premises.
So the contaminated egg may not have been the only problem.
Food preparation and kitchen hygiene can also play a role.
But the imported egg connection is sufficiently significant that the UK authorities are working with European health authorities to trace the source.
The supermarket is not the whole story and there is an important trap here.
You can walk into Lidl or Tesco, pick up a box of shell eggs and examine the packaging.
But what happens when you order eggs Benedict in a café or a cooked breakfast, mayonnaise, a cake, or a sandwich containing egg?
Suddenly the consumer has lost much of that visibility.
You might know that the café is buying British sausages and local bacon.
But you probably have no idea whether the eggs being used in the kitchen carry the British Lion mark.
And that may be one of the most important questions to come out of the current outbreak.
Should restaurants tell us? Perhaps they should.
I'm not necessarily suggesting that every restaurant should have to print the farm of origin on its menu.
But there is a reasonable argument for greater transparency.
If a restaurant advertises a breakfast containing eggs, should the customer be able to ask whether those eggs are British Lion?
And if the answer is no, should that information be readily available?
The supermarket consumer has a choice.
The restaurant customer often doesn't.
That seems like an odd gap in the food-supply chain.
What about Poland and Ukraine? Ddi you even think soe of our eggs are coming from those places.
There has also been considerable discussion about eggs coming into Britain from countries including Poland and Ukraine.
There are legitimate questions about the rapid growth in egg imports and whether imported production is always subject to exactly the same assurance standards as British production.
But we need to be careful.
The current investigation has not established that Poland or Ukraine is the source of this outbreak.
It has established an association with imported eggs.
That is not the same thing.
Blaming a particular country before investigators have identified the source would be irresponsible.
There is also an important distinction between legal food imports and food that fails to meet UK food-safety requirements.
Imported eggs entering the British market have to comply with applicable rules.
The debate is really about whether the controls and assurance systems behind imported eggs are equivalent to those that British consumers have become accustomed to through schemes such as Lion.
Scotland's six cases
For Scotland, the figures are worth watching.
Six Scottish cases have so far been linked to the national outbreak.
That is a relatively small number compared with the 199 cases recorded in England, but it is enough to demonstrate that Scotland isn't completely detached from what is happening elsewhere in Britain.
It would be wrong to describe this as evidence of a Scottish Salmonella epidemic.
We don't yet have the evidence for that.
But six cases linked to a national outbreak involving imported eggs should certainly make us interested in where the food reaching Scottish kitchens is coming from.
And that is particularly relevant in rural Scotland.
An egg consumed in Caithness may have travelled a considerable distance before it reaches a supermarket, wholesaler, restaurant or café.
Food supply chains have become increasingly complicated.
The consumer sees the egg.
Behind it sits a chain involving farms, packing stations, distributors, wholesalers, supermarkets and caterers.
The more complicated that chain becomes, the more important traceability becomes.
The little Lion could be more important than we thought
There is perhaps a broader lesson here.
For years, food labels have become increasingly complicated.
Free range.
Organic.
Barn.
Red Tractor.
RSPCA Assured.
British Lion.
We can sometimes switch off when confronted with all these logos.
But food scares remind us why some of them exist.
The British Lion mark provides consumers with information about the production system behind the egg.
It doesn't mean that Salmonella can never occur.
Nothing in food production can offer an absolute guarantee.
But it does indicate that the egg has been produced within a system containing additional controls specifically aimed at reducing Salmonella risk.
That is useful information.
So what should shoppers do?
The current outbreak is not a reason to stop eating eggs.
The FSA says its advice remains unchanged: eggs that are thoroughly cooked and handled hygienically should not present a food-safety risk.
For consumers, some simple precautions make sense.
Look at the packaging and check the egg itself.
If you want the additional assurance provided by the British Lion scheme, look for the Lion mark.
And if you are in a restaurant or café and you particularly want British Lion eggs, there is nothing unreasonable about asking.
Perhaps consumers will start doing exactly that.
Because there is an interesting irony in the current situation.
The supermarket may actually give you more information about your egg than the restaurant does.
Lidl tells us its shell eggs are 100% British and Lion assured.
Tesco puts British Lion information directly on its egg packaging.
The consumer can make an informed choice.
But once that egg disappears into a commercial kitchen, the trail becomes much harder to follow.
That is perhaps the real question the Salmonella outbreak should leave us asking.
Not simply:
"Are imported eggs safe?"
But:
"Why can't consumers always see the same level of information about the eggs they are served as they can about the eggs they buy?"
In an age when we are increasingly told that consumers want to know where their food comes from, perhaps it is time to make that information easier to find.
The little Lion on the side of an egg box suddenly looks rather more important than it did a few weeks ago.
