Chicago Food Poisoning Lawyer
If you were sickened by contaminated food from a restaurant, grocery store, or packaged product in Chicago or the surrounding Cook, DuPage, Will, and Kane County communities, Ori Law Group can help. Food poisoning claims aren't built on a single special statute — they run on Illinois product liability and negligence law, treating contaminated food as a defective product. The hard part is proof: linking your specific illness to a specific source through lab testing, health-department outbreak investigations, and genetic matching of the pathogen. Joe and Kristen Ori personally handle every food poisoning case from intake through trial; you will never be handed off to a junior associate or an intake screen. With more than 40 years of combined trial experience and over $150 million recovered, we hold restaurants, food manufacturers, grocers, and distributors accountable when their products make people sick.
If you were sickened by contaminated food, the question that decides your case is usually simple to state and hard to answer: can you prove that a specific food, from a specific source, made you sick? At Ori Law Group, that’s where Joe and Kristen Ori start. Food poisoning claims aren’t built on some special statute written just for foodborne illness — they run on Illinois product liability and negligence law, which treats contaminated food the same way it treats any other defective, dangerous product. A restaurant, manufacturer, grocer, or distributor that puts tainted food into the stream of commerce can be held responsible for the harm it causes.
The challenge is proof. Pathogens like Salmonella, E. coli O157:H7, Listeria, norovirus, Hepatitis A, and Campylobacter all cause illness, but tying your case to one source takes evidence most people don’t think to gather while they’re sick. That’s why we tell clients to do three things early: keep the receipt and any leftovers, get a stool test, and report the illness to the health department. A lab-confirmed pathogen, a health-department outbreak investigation, and a genetic match — through methods like PFGE and whole genome sequencing — are what connect your specific illness to its source. We move quickly to preserve all of it, because leftovers get thrown out, packaging gets recycled, and a restaurant’s records get overwritten within days.
The stakes can be severe. E. coli O157:H7 can cause hemolytic uremic syndrome and kidney failure, especially in children; Listeria threatens pregnant women and newborns; and what starts as a few days of illness can leave lasting digestive and neurological complications. Some of the most serious cases aren’t local at all — they come from packaged products distributed nationwide, where a single contaminated batch sickens people across many states. We handle those multi-state outbreak claims and pursue out-of-state manufacturers and grocery chains that put a contaminated product on Illinois shelves.
Because we’re a two-attorney boutique, Joe and Kristen personally investigate every food poisoning case from intake through trial — across Chicago and the Cook, DuPage, Will, and Kane County suburbs. Food poisoning is one type of injury claim that turns on assembling careful proof; if a property hazard is what hurt you, see our Chicago premises liability lawyer page, and for the most serious outcomes see our pages on catastrophic injuries and slip and fall. The case review is free, there’s no upfront cost, and we work on a contingency basis, so you pay nothing unless we recover for you. Call Joe or Kristen at (312) 621-0000 to talk through what happened and what comes next.

What to Do After Your Accident
- Get medical attention right away and tell the provider you suspect food poisoning — ask for a stool test, because a lab-confirmed pathogen is the single strongest piece of evidence in these cases.
- Keep the receipt, packaging, and any leftover food exactly as it is — bag it, refrigerate or freeze it, and don't throw it away, because it may still be testable for the pathogen.
- Write down everything you ate in the days before you got sick, where it came from, and when your symptoms started.
- Report your illness to the local or Illinois Department of Public Health — an official outbreak investigation can connect your case to others and pinpoint the source.
- Save the names and contact information of anyone who ate the same food and also got sick.
- Do not give a recorded statement to the restaurant's or manufacturer's insurer, and talk to an attorney before accepting any settlement offer.
Common Causes & Types
- Salmonella — from undercooked poultry and eggs, raw produce, and cross-contaminated surfaces — a leading cause of hospitalized foodborne illness.
- E. coli O157:H7 — from undercooked ground beef, raw leafy greens, and unpasteurized products — capable of causing kidney failure, especially in children.
- Listeria — from deli meats, soft cheeses, and ready-to-eat foods — particularly dangerous to pregnant women, newborns, and older adults.
- Norovirus — spread by infected food handlers and contaminated surfaces — the most common cause of restaurant-linked outbreaks.
- Hepatitis A — spread by infected food handlers and contaminated produce — often triggering public health alerts and vaccination clinics.
- Campylobacter from undercooked poultry and raw milk, plus improper food handling, poor refrigeration, and failures to follow safe-temperature rules.
Who Can Be Held Liable
- Restaurants and food-service operators who served contaminated or improperly handled food
- Food manufacturers and processors whose product was contaminated before it reached the shelf
- Grocery stores and retailers who sold a tainted product
- Distributors, suppliers, and packagers in the chain that put the food on the market

How We Prove a Food Poisoning Case
The legal theory in a food poisoning case is usually straightforward: contaminated food is a defective product, and Illinois product liability and negligence law hold the businesses that made and sold it responsible for the harm it causes. The hard part is never the theory — it's proof. To win, you generally have to connect your specific illness to a specific source, and that connection is built from three kinds of evidence.
Lab confirmation of the pathogen. A stool test or other clinical lab work that identifies the exact organism that made you sick — *Salmonella*, *E. coli* O157:H7, *Listeria*, *Campylobacter*, or a virus — turns "I think it was the chicken" into documented fact. This is why getting tested early matters so much; without a confirmed pathogen, a case is far harder to prove.
Health-department outbreak investigations. When several people get sick from the same source, the local or Illinois Department of Public Health and the CDC investigate. Their interviews, inspection findings, and case counts can establish that an outbreak occurred and trace it to a particular restaurant, batch, or product.
Genetic matching to the source. Public health labs use methods like pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS) to fingerprint the pathogen in a patient and match it to the organism found in the suspect food or facility. A genetic match is powerful evidence that your illness and the contaminated product are one and the same.
We move quickly to preserve all three — your medical and lab records, the implicated food and packaging, and the public-health record — because each one is fragile and time-sensitive.
The Legal Basis: Product Liability + Negligence
Food poisoning claims don't rely on one special "food poisoning statute." They're built on the same Illinois law that governs any defective, dangerous product. A business that sells contaminated food can be liable under more than one theory at once.
Under strict product liability, a seller can be responsible for putting a defective and unreasonably dangerous product — contaminated food — into the stream of commerce, even without proof of carelessness. Under negligence, a restaurant or manufacturer can be liable for failing to follow safe food-handling, cooking, refrigeration, or sanitation practices a reasonable business would follow. Many claims also include a breach of warranty theory, since food sold for consumption carries an implied promise that it's fit to eat.
Because the chain from farm to plate involves many businesses, more than one company is often responsible — the manufacturer that shipped a tainted batch, the distributor that stored it improperly, and the restaurant or grocer that sold it. We identify every party in that chain so no responsible business escapes accountability.
Multi-State Outbreaks and Nationwide Reach
Many of the most serious food poisoning cases come from packaged products distributed across the country — a recalled batch of leafy greens, ground beef, or deli meat that sickens people in dozens of states. When that happens, the source is rarely a local Chicago restaurant; it's a national manufacturer or grocery chain. We handle these claims, coordinate with national outbreak data and recall records, and pursue out-of-state companies that put a contaminated product on Illinois shelves.
- Packaged-product outbreaks — recalled produce, meat, and ready-to-eat foods that sicken consumers across multiple states from a single contaminated source.
- National recalls — FDA and USDA recall notices that often signal which product, batch, or lot number caused an outbreak.
- Out-of-state defendants — manufacturers and distributors based outside Illinois who can still be held accountable for harm caused here.

Frequently Asked Questions
Do I have a food poisoning case if I just felt sick for a few days?
It depends on what you can prove and how serious your illness was. The strongest cases involve a lab-confirmed pathogen, hospitalization or significant medical treatment, and a traceable source. A brief, untested stomach upset is hard to tie to a specific restaurant or product. We give you an honest assessment after reviewing your medical records and the facts.
Why is a stool test so important?
A stool test identifies the exact organism that made you sick — Salmonella, E. coli, Listeria, Campylobacter, or a virus. That lab confirmation is often the single most important piece of evidence, because it turns a suspicion into documented fact and lets public health labs genetically match your illness to the contaminated source. Ask for one early, before your symptoms resolve.
How do you prove which food made me sick?
We build the connection from three sources: clinical lab testing that confirms your pathogen, health-department outbreak investigations that trace cases to a source, and genetic matching — methods like PFGE and whole genome sequencing — that fingerprint the organism in you and match it to the suspect food or facility. Together, these tie your specific illness to a specific source.
Who can be held responsible for food poisoning in Illinois?
More than one business is often liable. A claim can reach the restaurant or grocer that sold the food, the manufacturer or processor whose product was already contaminated, and the distributors and suppliers in between. Food poisoning claims run on Illinois product liability and negligence law — contaminated food is treated as a defective product — so we pursue every party in the chain.
What if E. coli caused kidney failure or HUS?
E. coli O157:H7 can cause hemolytic uremic syndrome (HUS), a serious complication that can lead to kidney failure and is especially dangerous for children. These are catastrophic, high-value cases that often involve dialysis, long-term care, and permanent organ damage. We work with medical experts to document the full extent of the harm and the lifetime cost of care.
Can I sue if I got sick from a packaged product sold in another state?
Yes. Many serious outbreaks come from packaged products distributed nationwide — recalled produce, meat, or deli items from a single contaminated batch. The responsible party is often a national manufacturer or grocery chain rather than a local restaurant. We handle multi-state outbreak claims and can pursue out-of-state companies that put a contaminated product on Illinois shelves.
How long do I have to file a food poisoning claim in Illinois?
You generally have two years from the date of injury under 735 ILCS 5/13-202, though the clock can start when you discovered, or reasonably should have discovered, that contaminated food caused your illness. Deadlines for injured minors are generally tolled until age 18, and wrongful death claims run two years from the date of death. It's best to act well before any deadline so evidence can be preserved.
What does it cost to hire Ori Law Group?
There is no upfront cost. We handle food poisoning cases on a contingency basis — we are paid a percentage of your recovery only if we win or settle your case, and your consultation is free. You pay nothing out of pocket to get started.
