Meatpacking giant closes South Dakota plant 'indefinitely' after almost 300 employees test...

I'm sure. I am guessing there will be a limit on pork and bacon soon too!

Yes, plants like that tend to have a very high immigrant population working at them. These people tend to live in substandard housing with many more people working at the same facility. It is possible that not all the spread of the virus happened at work.

Note: the lady being interviewed is from an immigrant advocacy group. There is more to this story. The use of immigrants both legal and illegal in our meat packing industry is quite well known. Not going to pass judgement on any type of immigration debate here. Just stating what I’ve seen from plants around here. Hey Marty, you’re in the general area. What do you guys hear about it?

Ok let’s say all food production stops in this country. How long do you think it would be for the supply chain to empty out at the consumer’s end? I’d say about 3 weeks MAX... shorter for some items. We don’t have large amounts of stock built in to our supply chains any more in just about any industry. Just in time delivery has cut cost from the system, having inventory is a large cost but, has also left has extremely vulnerable to this type of supply chain disruption. Food production workers are considered “essential workers” and most definitely would be working during this. However, the company should have taken more care to separate workers as much as possible and supplied all workers with masks too.
