Foodservice net sales increased $300.9 million, or 30%, to $1,318.2 million, compared with $1,017.3 million in fiscal 2021. Volume and price/mix each increased 15%. The benefits of product and freight pricing actions taken throughout the year to offset inflation, as well as favorable mix, drove the increase in price/mix. The segment’s strong volume growth reflects the progressive recovery in demand in its restaurant and non-commercial channels, although growth was tempered by an inability to fully serve customer demand due to widespread industry supply chain constraints, including labor shortages, that resulted in lower production run-rates and throughput in our production facilities.
Retail net sales decreased $8.8 million, or 1%, to $594.6 million, compared with $603.4 million in fiscal 2021. Volume declined 8% while price/mix increased 7%. Lower shipments of private label products, resulting from incremental losses of certain low-margin business, as well as lower shipments of branded products, drove the sales volume decline. The decline in branded product volume reflected an inability to fully serve customer demand due to lower production run-rates and throughput in our production facilities. Product and freight pricing actions across the branded and private label portfolios to offset inflation, as well as improved mix, drove the increase in price/mix.
Net sales in our Other segment declined $16.8 million, or 12%, to $121.9 million, compared with $138.7 million in fiscal 2021. The decline primarily reflects lower volume in our vegetable business, reflecting the negative effect of the extreme summer heat on the yield and quality of the vegetable crops, partially offset by the benefit of pricing actions.
Gross Profit and Product Contribution Margin
Gross profit in fiscal 2022 was flat compared to fiscal 2021 at $832.0 million, as the benefits from higher price/mix and volume were offset by the impact of higher manufacturing and distribution costs on a per pound basis. The higher costs per pound primarily reflected double-digit cost inflation from key inputs, including: edible oils; ingredients such as grains and starches used in product coatings; packaging; labor; and higher transportation costs. The increase in costs per pound also reflected higher raw potato costs due to the impact of extreme summer heat that negatively affected the yield and quality of potato crops in the Pacific Northwest in fall 2021, the effects of labor and commodities shortages on production run-rates, as well as lower raw potato utilization rates. The increase in per pound costs was partially offset by securing changes to product specifications, portfolio simplification, and driving supply chain savings behind our Win as 1 productivity program. Gross profit also included a $28.9 million decrease in unrealized mark-to-market adjustments associated with commodity hedging contracts, which includes a $9.5 million loss in the current year, compared with a $19.4 million gain related to these items in the prior year.
Lamb Weston’s overall product contribution margin in fiscal 2022 declined $1.1 million to $813.1 million, compared with $814.2 million in fiscal 2021. The decline was largely due to a $1.1 million increase in A&P expenses as gross profit was flat (as described above).
Global product contribution margin declined $54.0 million, or 18%, to $252.2 million in fiscal 2022. Higher manufacturing and distribution costs per pound more than offset the benefit of favorable price/mix and higher sales volumes. Global segment cost of sales was $1,806.6 million, up 13% compared to fiscal 2021, primarily due to higher manufacturing and distribution costs and higher sales volumes.

Retail product contribution margin declined $10.8 million, or 9%, to $109.4 million in fiscal 2022.
