Food companies in Chicago: the largest food manufacturing workforce of any US metro, by plant, product and owner

This report is for people who need Chicago's food makers as a market: buyers sourcing products or co-packers, job seekers, and suppliers of ingredients, packaging, equipment and services. "Food companies" here means food manufacturers; restaurants, grocers and distributors are separate industries.

Chicago's food manufacturing in Census data

County Business Patterns 2023, NAICS 311 (food manufacturing), Chicago-Naperville-Elgin, IL-IN Metro Area (CBSA 16980):

In the same metro file, the New York (2,233) and Los Angeles (1,506) metros have more food manufacturing establishments, but neither has as many employees: Los Angeles has 48,014 and New York 47,956. That ranking is our calculation.

In broader bands: 684 establishments have 1 to 19 employees, 233 have 20 to 99 and 148 have 100 or more. The 75 sites with 250 or more people are the plants that anchor the industry.

What Chicago makes

From the County Business Patterns 2023 metro file; per-site averages are our calculation.

Bakeries are half the establishments, but meat plants are the big employers: 93 sites averaging 155 people. Confectionery averages 100 per site.

Cook County has 61% of the establishments and 63% of the jobs. Kane County's 56 sites average 81 employees, larger than Cook's 59. County Business Patterns counts establishments with paid employees, not companies, and classifies each by its main activity, so a company's headquarters may be counted outside food manufacturing.

Food companies headquartered in the Chicago area

Revenues, net revenues or net sales as each 10-K reports them. Kraft Heinz gives One PPG Place, Pittsburgh, as its principal executive offices and describes Pittsburgh and Chicago as its corporate co-headquarters.

A headquarters isn't a plant. These companies' factories may be anywhere, and Census may count their Chicago offices under other codes, such as management of companies. For plant-level prospecting, use the Census size data and the city's license records.

Chicago's own license records

The City of Chicago publishes its active business licenses on its data portal. As of 29 October 2026 the city of Chicago itself (not the suburbs) has:

The shared kitchen numbers are the pipeline: hundreds of small food businesses producing in licensed shared kitchens before they have a plant of their own. Each license record has the legal name, business name and address, so the dataset doubles as a prospect list for the city.

Finding a Chicago food maker or co-packer

• For co-packers and co-manufacturers, the Chicagoland Food & Beverage Network keeps a members' directory of vetted co-packers, co-manufacturers and service providers.
• For any maker in the city, filter the city's license data by license type and business activity, then confirm the business is active.
• For food safety rules, the Illinois Department of Public Health's food safety pages cover the state's programs.
• Before you contract, ask whether the plant is registered with FDA if it ships across state lines; FDA's list of registered food facilities isn't public.

Selling to Chicago food manufacturers

Plants buy through the plant manager, the food safety or quality manager and, at the larger companies, corporate procurement. Sanitation, maintenance, packaging and ingredients are recurring needs; audits and new product launches are the triggers.

Illustrative example. The sanitation company, rates and results are invented; the plant counts are from Census data.

Prairie State Sanitation (prairiestatesanitation.example) supplies overnight sanitation crews to food plants. It targets meat plants and bakeries with 50 to 499 employees in the metro: 39 meat establishments and 56 bakeries in Census data, 95 in all. At each it contacts the plant manager and the food safety manager, about 190 people. Eight contracts at $250,000 a year would be $2 million. Its triggers are a failed or upcoming audit and a plant expansion.

Subject: Sanitation coverage at [plant]

Hi [first name],

[Company] is [adding a line / hiring production staff] at [plant]. More production hours usually means a shorter sanitation window and more pressure on the crew you have.

We run overnight sanitation for Chicago-area meat and bakery plants, with crews trained on your SSOPs and documentation ready for your next audit.

Would it help to walk your plant with our operations lead next week?
