The Covid-19 pandemic has disrupted the operation of many businesses, including the supply chain process in USA schools. Multiple lockdowns experienced have slowed or temporarily stopped food production in the country, which has led to lunch shortages in schools. Other possible causes of food shortage in schools may include government restriction on movement to reduce coronavirus spread, limiting many farmers to access the market and farm input. As a result, they could reduce their production or farming capacity.

Restriction of movement of other countries, significantly where USA government import food from, could have also reduced the production process. As a result, importation of food goes down and could have led to food shortage in USA schools. Working from home is another factor contributing to food shortages, and many organizations are working remotely, which might affect production capacity as well. There has also been under-investment in the agriculture sector, which could lead to low supply.
