Let’s start with how to put down fries. You just grab a basket and head over to the topper machine, push down 2 shot of fries in one basket. Then drop them down at the fryer and pressing the 1 or 2 button at the fryer. Around 3 min mark they will display DUTY and all you have to do is press the button.

We don’t recommend going any longer than 24 hours at room temperature because the grounds’ bitterness will come back, and the coffee will develop a woody or dusty taste. You could steep for longer time if you put the cold brew in the fridge.

bacteria grow rapidly at temperatures between 40°F – 140°F. In general, cooked fries should be discarded after two hours if left at room temperature. A sealed container with fries will certainly accelerate the temperature and humidity that fuels bacteria growth, so figure even less time for safe consumption.

It has been revealed that McDonald’s fries do contain an animal product – Milk. They also contain wheat. There are thousands and thousands of people around the world who are allergic to wheat (mainly because of the gluten in wheat).

More recently, Serratia marcescens has been found to be pathogenic to a small percentage of people, having been identified as a cause of urinary tract infections, wound infections, and pneumonia in hospital environments.

Symptoms may include fever, frequent urination, dysuria, pyuria, or pain upon urination. In 90% of cases, patients have a history of recent surgery or instrumentation of the urinary tract.

S. marcescens has been shown to cause a wide range of infectious diseases, including urinary, respiratory, and biliary tract infections, peritonitis, wound infections, and intravenous catheter-related infections, which can also lead to life-threatening bacteremia.
