My local news is telling me again that eating food from the local take out is no risk because when you swallow it your stomach acids kill the virus.
THEY DON'T KNOW THAT! Who tested it? If that's true how are we getting infected from droplets hitting our mouths?
They don't know that for sure, but when a virus is constructed the way this one is, it's quite likely this is generally true. The lipid layer would not survive stomach acids and digestive enzymes in the majority of people.
Viruses that specialize in an intestinal route of infection, like noro or canine parvovirus, are generally much more sturdy in their construction (and can linger for much longer in the environment too).
More and more experts are saying the evidence is that aerosols are the likeliest source of spread, but droplets may still be a factor too, though the conjunctiva, and possibly nasal mucosa, are likelier routes of entry than the mouth.

BUT, some people (such as people on proton pump inhibitors) have low stomach acidity. And some people have conditions that reduce the integrity of their intestinal mucosa. They may be at elevated risk for contacting it via an oral route. A certain percentage of people present with gastrointestinal symptoms as well, and it's possible they were infected via an oral route (though that's not a given).
The intestinal tract may have been an alternative source of infection for at least some cases of MERS.

I think a certain amount of caution makes sense, but people still have to eat. I clean packages that come into the house still, and if something can't be cleaned and must be opened right away, I open it carefully. People who are immune compromised should probably be extra careful, as it would likely take contact with fewer viral particles to infect them than the norm.
I am especially careful with stuff going into the fridge or freezer, because there is evidence the virus survives longer in cold environments. I'm much more worried about catching it from someone in the grocery store, however, than from the food I bring home. It doesn't help that some people are still ignoring social distancing recommendations. Also, why are stores still so crowded? If we're all limiting our shopping to 1 trip a week or fewer to the grocery store, why are there so many more folks in the store now than normal? I get that people will buy more when they are there, as they appear to be doing (judging by the fact that things are still running out), but why are they returning so often if they've stocked up?
