Can You Catch Covid From Groceries?

By Dr Carl Heneghan and Dr Tom Jefferson | Trust the Evidence | December 3, 2022

The BBC’s pandemic coverage has strictly followed what is now known as official science. No questions asked; just report what you are told.

One of the most incredible features of the media coverage has been the ignorance of existing research on respiratory viruses. We use ignorance as a generic term as we are unsure whether the reporters were ignoring the large existing body of knowledge or were ignorant, i.e. did not know it existed.

Now we have the latest fantastic revelation: respiratory viruses, specifically SARS-CoV-2, “survive” for days on certain types of surfaces and foodstuffs, from pastries to canned products.

The news item is from a Food Standard Agency laboratory study carried out using credible methods: viral cultures.

Except that the final paragraph of the discussion hints that something is not quite right:

“The public may be interested in the finding that virus may persist in an infectious state, on foods and food packaging surfaces, for several days under certain common conditions. There is the possibility of transmission through contaminated food if the food is in direct contact with the mouth and mucus membranes. The potential implications for public health are unclear since inhalation of respiratory aerosols and droplets is considered to be the main route of SARS-CoV-2 transmission”.

Readers of our transmission riddles will know by now that such statements are hostages to fortune; the “main route” would need a lot more evidence than presently available to make it “main”, whereas fomites so far tick more boxes. So if we are to follow good evidence the reverse is the case. The sentence in the Discussion should read “how does such a high quality evidence from laboratory and human observations fit with certainty that inhalation of respiratory aerosols and droplets are the main route of SARS-CoV-2 transmission?”

Does the BBC piece put the study into the context of transmission: no. Does it refer to the available evidence for this and other respiratory viruses suggesting a more complicated transmission scenario: absolutely not. Do you go away with a feeling that if you touch a vegetable in a supermarket, you will end up in bed coughing?

About 15 years ago, Mike Broderick and colleagues followed the incidence of febrile acute respiratory infections (ARIs) caused by adenovirus in military units. They divided the units into “open” and “closed” according to whether they allowed potentially infectious convalescent soldiers to join or not. This was a proper study with viral cultures accompanied by PCR testing. The authors also went a bit further by sampling surface structures looking for viable adenovirus even in barracks which had been disused for some time. There was no difference in incidence between closed and open units. A result that mirrors our findings of hospital-acquired infection following viral circulation in the community (within a few days’ lag time), implying that measures such as distancing and barriers did not make any difference.

There’s more. Up to eight per cent of samples from surfaces in barracks which had not been used for a week turned up viable adenovirus, and the authors conclude that the source of the agent is environmental. Precisely what was found in several studies in daycare centres for young children in Denmark, where all types of respiratory and enteric viruses and bacteria populated soft toys, tables, and sofas.

To add to the body of pre-existing evidence, our review of SARS-CoV-2 found 23 studies that investigated fomite transmission and performed viral culture. Five studies demonstrated that replication-competent SARS-CoV-2 is present on fomites. Four of these were done in hospitals, and in the further study, two Chinese dock workers were found to have asymptomatic SARS-CoV-2 infection during routine screening; the two workers were infected after contact with contaminated outer packaging from a fish cluster pallet.

A noteworthy aspect of establishing transmission is determining the minimum dose of virus particles that can initiate infection – the “minimal infectious dose” Data from a recent human challenge trial showed an intranasal exposure to one million genome copies might be required to yield approximately 50% chance of infection. A positive SARS-CoV-2 culture from fomites is at least three times more likely when the cycle threshold value is less than 30 (i.e., the sample has a higher viral load), and a plausible chain of transmission is strengthened by the presence of studies demonstrating genomic sequencing.

Science is cumulative. The BBC reporting would be enhanced if it set the findings of new studies in the context of what is known. It doesn’t take much to systematically search for what is already known. If reporters did so, the public might better understand the evidence – as opposed to the opinions – for how viruses are transmitted.

  1. This is beginning to sound like the alibi of the unfaithful spouse, claiming to have caught gonorrhea off the toilet seat. Surely through the paper liner placed on the toilet seat. I am beginning to think that one can get infected with covid simply by thinking about it too much. in fact, the more we talk about it, the more covid related issues we have. It will soon blend in with and comingle with climate change, necessitating new solutions and draconian actions on the part of governing criminals, aided by the sage advice and funding by omniscient billionaires who care intensely about the welfare of the masses.

    • Or perhaps they plan to impose food delivery and shutter the stores. Everyone gets a box once per week.

      • Ok, but even according to such a plan, the delivered box could have covid all over it.

          • And even the gloves can have covid on them. the zombies who walk around the park or who drive alone in their cars with all window up seem to believe that the earth’s air consists of…oxygen, nitrogen, and covid. The zombies who wear their masks under their noses or over thick beards are a few notches above the nth degree of incomprehensible. So do wear those gloves but make sure that you also disinfect them with sanitizer. Come to think of it, perhaps we should wash all our edibles in sanitizer, before eating.

  3. As I understand it, a virus is not a discrete living organism. It is, for want of a better description, a catalyst, which can only function in a living host – the human body. There is also much debate about the pathogenicity of viruses, and that can only be proved by isolation, purification and testing – which, in the case of covid-19 – has not taken place. Therefore, to claim that ‘infectious’ viruses can exist on food and other surfaces for several days is either an outright lie/propaganda or scientific ignorance.

    However, because bacteria are living organisms, infection from foodstuffs and surfaces is possible, but because they do not fit the ‘pandemic’ narrative and the ‘invisible pathogen’ bogeyman, they are dismissed. In this narrative ‘virus=pathogen’, and awkward questions about transmission are answered with fantasies (which too many people accept as ‘truth’).

    • Yes, but most of the false narratives are intended for those who have elected to not think things through, or do not possess the more detailed information that you present. And the reason such narratives have such remarkable success in being believed is the remarkable number of the world’s population who have elected to not think. Too often this election stems from ego and pride. Other times from fear or the desire to go along just to get along, but the end result is the same. Demagogues win.
