It's a thing to worry about, Jenise, that's for sure! It does seem that the virus doesn't spread via oral transmission and the digestive system, though. A guy on the LouisvilleHotBytes forum just posted this copy-and-paste from Serious Eats, which I hadn't seen yet. It's pretty reassuring.

According to multiple health and safety organizations worldwide, including the CDC, the USDA, and the European Food safety Authority, there is currently no evidence that COVID-19 has spread through food or food packaging. Previous coronavirus epidemics likewise showed no evidence of having been spread through food or packaging.
Are we sure food isn’t a vector of COVID-19 transmission?
No, we don't know for sure. However, there is strong evidence to suggest that food is not a vector. The epidemiology of food-borne pathogens is well studied, with government data going back to 1938. The spread pattern of COVID-19 does not fit models of foodborne outbreaks, which are defined as two or more people getting sick from the same contaminated food or drink.
For instance, Singapore has tracked its COVID-19 patients and submitted them to extensive interviews by teams from the Ministry of Health to try to determine patterns of spread. It's been found that most cases are linked to clusters of people, including hotel guests attending conferences, church groups, and shoppers, while none are linked to contaminated food or drink.
The fact that every person eats multiple times a day and thus far no link has been found between eating and viral clusters is strong evidence that no such link exists.
I’m still not convinced. How could food not be a vector?
Let’s say a food worker coughs while preparing my food, how could I not pick up the virus from eating it? This confused me as well, which is why I specifically inquired about it. According to Chapman, the risk is minimal. Even if a worker sneezes directly into a bowl of raw salad greens before packing it in a take-out container for you to take home, as gross as it is, it's unlikely to get you sick.
This 2018 overview of both experimental and observational study of respiratory viruses from the scientific journal Current Opion in Virology (COVIRO) explains that respiratory viruses reproduce along the respiratory tract—a different pathway than the digestive tract food follows when you swallow it. And while you might say that you just inhaled that salad, more likely you ate it with a fork and swallowed it.
