Abstract
Modern food systems depend on continuous movement. Agricultural inputs reach producers, raw materials arrive at factories, finished products move through distribution centres, and retailers replenish their shelves.
When these connections function reliably, maintaining relatively low inventories can reduce storage costs, working-capital requirements, and waste.
However, transport disruptions can quickly expose the limits of this approach.
In October 2026, protests by truck drivers in Italy interrupted deliveries of food and manufacturing inputs. Some pasta producers reduced or suspended production because essential raw materials were no longer arriving.
At the same time, perishable foods became stranded in trucks and warehouses, creating losses despite the continued physical availability of products.
The disruption illustrates two different inventory challenges.
For shelf-stable ingredients, existing stocks can allow factories to continue operating temporarily when deliveries stop.
For perishable products, additional inventory may provide little protection if transport remains blocked and goods cannot reach consumers before deteriorating.
The question is therefore not simply how much food should be stored.
It is how inventory can support continuity while transport, sourcing, and distribution arrangements recover.
This research examines the role of inventory in food-system resilience and why the appropriate level of protection differs across products and supply chains.
1. When Transport Disrupts Production Without Damaging Factories
On 20 October 2026, Reuters reported that protests by truck drivers in southern Italy were disrupting deliveries to pasta manufacturers.
The protests were linked to rising fuel prices and living costs, with transport restrictions affecting important road connections.
Pasta producer Rummo, based in Campania, reported that it had suspended production after exhausting its available ingredients.
La Molisana, based in Molise, reported a significant reduction in production while relying on existing stocks of raw materials, including wheat and semolina.
These cases illustrate an important distinction.
Manufacturing facilities may retain their machinery, workers, and technical capacity while becoming unable to operate normally because essential inputs cannot reach them.
A factory’s installed capacity does not guarantee that production can continue during a logistics disruption.
For Rummo, the exhaustion of available ingredients contributed to a production halt.
For La Molisana, existing inventory allowed some production to continue, although at a reduced level.
The difference demonstrates the immediate protective role that raw-material stocks can provide.
However, the available reporting does not establish the exact inventory coverage, in days, held by either company before the disruption.
It therefore cannot determine whether a particular inventory target would have prevented the interruption.
2. Inventory Protects Operations for a Limited Period
Inventory allows businesses to continue using materials that were delivered before a disruption began.
For a food manufacturer, stocks of essential ingredients can reduce dependence on immediate replenishment.
The protective value of those stocks depends on how quickly they are consumed.
A given quantity of raw material may support several days of production at one factory but a much shorter period at another.
This is why inventory volume alone provides an incomplete picture of resilience.
Production rates, material requirements, storage conditions, and the duration of supply interruptions all affect how long operations can continue.
The distinction also applies to different locations within the food system.
Raw-material inventory may protect factory production.
Finished-goods inventory may allow distributors to continue supplying retailers when manufacturing is interrupted.
Retail inventory may protect consumer access during a temporary delivery delay.
These stocks perform different functions and are not always interchangeable.
A warehouse containing finished pasta cannot necessarily replace the ingredients required to restart a factory.
Similarly, raw materials stored at a manufacturing site do not guarantee that finished products can reach consumers if outbound transport is blocked.
Inventory can therefore delay the consequences of interrupted movement.
It cannot independently restore the connections on which the wider food system depends.
3. Perishable Food Presents a Different Inventory Problem
The Italian transport disruption also affected products that cannot remain in storage indefinitely.
On 21 October 2026, Reuters reported that Italian retailers were warning of food shortages as deliveries remained disrupted.
ANCD-Conad, representing retailers operating under the Conad supermarket brand, reported that substantial quantities of fruit, vegetables, milk, and meat were stranded in trucks and warehouses.
The problem differed from the shortage of ingredients experienced by pasta manufacturers.
For some manufacturers, insufficient incoming inventory threatened production.
For producers and distributors of perishable food, existing goods could become unsaleable because they were unable to move through the distribution system.
This distinction matters for inventory policy.
Shelf-stable products such as dry pasta, grain, and some packaged foods can often be stored for relatively long periods under suitable conditions.
Fresh produce, milk, and meat have more restrictive handling and storage requirements.
Refrigeration can extend the usable life of many perishable products, but it introduces additional requirements for electricity, equipment, maintenance, and appropriate temperature control.
Cold storage also cannot extend shelf life indefinitely.
Holding more perishable inventory may therefore increase potential losses when transport disruptions prevent timely delivery.
For these products, reliable movement and the availability of alternative distribution arrangements can be more valuable than simply increasing stock.
The Italian case shows that the same transport interruption can create shortages in one part of the food system while leaving excess or deteriorating goods elsewhere.
4. The Location of Inventory Matters as Much as Its Quantity
Food inventories are distributed across farms, factories, warehouses, vehicles, distribution centres, and retail outlets.
Their usefulness depends partly on where they are located relative to the disruption.
A large quantity of food stored at a central warehouse may offer limited protection to retailers if transport access to that warehouse is interrupted.
Conversely, regional inventories may help maintain local availability when a particular transport corridor becomes unavailable.
However, distributing inventory across more locations creates additional costs.
Businesses may need more storage facilities, handling equipment, staff, and working capital.
Some products may also experience higher spoilage or inventory-management costs.
Centralized storage can be efficient under normal operating conditions.
Distributed storage may provide greater flexibility during certain disruptions.
Neither arrangement is universally superior.
The appropriate choice depends on product characteristics, geographic exposure, transport connectivity, and the cost of maintaining additional facilities.
The Italian disruption illustrates why food availability cannot be inferred from the total quantity of food physically present in a country or region.
Products must remain accessible to the businesses and consumers that need them.
When movement is interrupted, local shortages can coexist with stranded inventory elsewhere.
5. Alternative Suppliers and Transport Routes Reduce Dependence on Stock
Inventory is one way to protect a food business against interruptions.
Another is to maintain access to alternative sources of supply and distribution.
A manufacturer with more than one qualified supplier may be able to obtain ingredients from another location when its normal delivery route becomes unavailable.
Similarly, access to different transport modes may provide options when a particular road or logistics corridor is disrupted.
However, these alternatives must be operationally available.
An alternative supplier may not have sufficient spare capacity.
Its products may require additional quality or food-safety approval.
A different transport route may involve higher costs, longer delivery times, or incompatible loading facilities.
The existence of another supplier or transport mode therefore does not automatically guarantee continuity.
Businesses may need to establish alternative arrangements before a disruption occurs.
Inventory can provide time for those arrangements to become effective.
This creates a relationship between stockholding and operational flexibility.
A business with limited alternatives may require more inventory to withstand a comparable interruption.
A business with reliable alternative supply and transport arrangements may be able to recover with less stock.
The appropriate balance depends on actual capabilities rather than the number of options listed in a contingency plan.
6. Resilience Has a Financial and Environmental Cost
Maintaining additional inventory requires investment.
Food businesses must purchase and store products before those products are sold or used.
This ties up working capital that could otherwise support equipment, labour, maintenance, or business development.
Storage facilities also involve operating expenses.
Refrigerated and frozen products may require continuous energy consumption, while other goods can incur handling, insurance, monitoring, and quality-control costs.
For perishable products, excessive stockholding may increase spoilage and food waste.
These costs create an important trade-off.
Low inventory can improve efficiency when deliveries are reliable.
Higher inventory may protect operations during interruptions but increase costs during normal conditions.
The economically appropriate level is therefore not necessarily the maximum quantity that can be stored.
It depends on the cost of maintaining additional stock compared with the potential consequences of shortages or production interruptions.
Those consequences can include lost sales, idle production capacity, emergency transport expenses, spoiled products, and reduced customer access.
For essential foods, the wider social consequences may also matter.
A shortage of a critical nutritional product can create risks that extend beyond the financial losses of the companies involved.
Inventory decisions therefore have both commercial and public-policy dimensions.
7. Public Food Reserves Serve a Different Purpose
Commercial inventories and public food reserves are designed for different objectives.
Private businesses generally manage inventory to maintain operations, serve customers, and control financial risk.
Governments may also consider food security, emergency access, and the availability of essential products during major disruptions.
Strategic reserves can provide additional protection for certain shelf-stable staples.
However, public stockholding also involves costs, storage requirements, product rotation, and decisions about when reserves should be released.
Large-scale public purchases or releases can influence market prices and commercial incentives.
Highly perishable foods are generally more difficult to maintain in long-term strategic stockpiles.
For those products, protecting cold-chain infrastructure and distribution continuity may be particularly important.
Public reserves cannot replace a functioning commercial food system.
Nor can commercial inventory always address emergencies that affect access across a large population.
The two may provide complementary forms of protection, depending on the commodity and the nature of the disruption.
The Italian case does not establish the appropriate size of any national food reserve.
It demonstrates the importance of distinguishing between a shortage of available food and an interruption in the systems that move food to where it is needed.
8. Why There Is No Universal Inventory Target
The amount of inventory needed to withstand a transport disruption varies considerably.
Shelf-stable products may support longer storage periods.
Perishable foods may require rapid distribution and reliable temperature control.
Manufacturers depend on specific inputs, while retailers depend on the timely arrival of finished products.
Businesses also differ in their access to suppliers, transport networks, storage facilities, and financial resources.
The duration of a disruption introduces further uncertainty.
A short interruption may be absorbed through existing stocks.
A longer disruption may require alternative suppliers, different routes, or changes to production and distribution arrangements.
A prolonged loss of transport connectivity may exceed the practical protection that additional inventory can provide.
For this reason, the Italian case does not support a universal recommendation that food companies should hold a fixed number of days of stock.
It also does not establish the optimal inventory level for pasta manufacturers, fresh-food distributors, or public food reserves.
Those decisions require information about consumption rates, product shelf life, replenishment conditions, disruption exposure, and recovery capabilities.
The more useful principle is that inventory should support continuity while the wider supply chain responds.
Its value depends not only on the quantity stored, but also on whether businesses can restore or replace interrupted flows before the available stock becomes insufficient or unusable.
Research Conclusion
The October 2026 transport disruption in Italy demonstrates that food systems can experience serious operational problems even when production facilities remain physically intact and food products continue to exist within the supply chain.
Rummo suspended pasta production after running out of ingredients.
La Molisana reduced production while relying on existing raw-material stocks.
At the same time, retailers reported that perishable foods were stranded in trucks and warehouses, contributing to shortages and deterioration.
These developments reveal different forms of vulnerability within the same food system.
For manufacturers dependent on shelf-stable ingredients, inventory can temporarily protect production when deliveries are interrupted.
For highly perishable products, maintaining transport and distribution may be more important than increasing the quantity held in storage.
The appropriate response also depends on where inventory is located, how quickly it is consumed, and whether alternative suppliers or transport arrangements are available.
Holding more stock can reduce some risks, but it creates financial, operational, and environmental costs.
The objective is therefore not to maximize inventory across the food system.
It is to maintain sufficient continuity without creating excessive waste or unnecessary expense.
Inventory is most valuable when it provides enough time for a food system to respond to disruption. It is not a substitute for the ability to restore movement.
This distinction has implications for manufacturers, distributors, retailers, and public authorities.
Food-system resilience depends on more than the volume of products stored.
It also depends on whether those products can continue reaching the places where they are needed.
Evidence and Limitations
This research draws primarily on Reuters reporting published on 20 and 21 October 2026 concerning transport protests, pasta manufacturing, and food distribution in Italy.
The reported operational conditions at Rummo and La Molisana are attributed to the companies and sources identified in contemporary reporting.
The discussion of stranded perishable goods reflects statements reported from the Italian retail sector.
The analysis does not establish the precise number of inventory days held by affected manufacturers or distributors.
It does not calculate an optimal national or commercial stockholding level.
The broader discussion of inventory costs, supply alternatives, and food-system resilience is an analytical interpretation of supply-chain principles rather than a claim that those specific measures were implemented by the affected Italian businesses.
