Rust In Ice Makers

I just need to find out want danger does rust impose in food , apparently our ice maker has rusted and the ice coming out is used for production.
Rust proof locks for a chemical cage
How to prevent rust in cans after sterilization?
Food-Grade Rust Sealant?
Food Grade Rust Inhibitor
Food grade rust preventive for molds

I would immediately stop using this machine and switch to bought in ice until it could be replaced.
There's the obvious foreign body hazard. Rust has a habit of breaking off in pieces not just staying where it is. If it's in contact with or over the ice, it's a major issue and needs dealing with.
There is also a microbiological risk too. Once a surface is damaged, in this case by rust, it's no longer smooth and easily cleanable, therefore you can't clean it properly and the pieces of rust breaking off could be carrying pathogens.
Ice machines are often overlooked from a hygiene perspective but I've known them to be sources of contamination.
I recommend replacing the machine rather than repairing it because if it's rusty, then was the quality of steel high enough to be in contact with food?

My Question to Concern- What Injection is given if you are pricked with rusty nail?
Yes - ATC- Anti Tetrac.
Why?
Because Tetnus Bacteria is always associated with rust.
Hence Iron is not allowed in food inductry.
Use the Good Quality Stainless Steel - SS 308 for making any equipment for food processing.
If any equipment is made of iron or ss quality is not good then rust will come and tetnus is not far.
Hence ideal situation is change the equipment.

Dear Chauke,
It depends on the type of freezer and internal / external design but one cause not always obvious is breaking / broken bearings in mechanical parts which will require changing immediately (often by manufacturer's original materials also).
Hopefully yr input water is OK.
Yr observation is normally considered a critical defect IMEX in relationship to the fundamental importance of "clean" water and "clean" ice.

Dear Chauke,
The hazards from rusty equipments (any equipment used for food preparation) can lead to physical, chemical and microbiological hazards which can cause adverse health effects. The ice which is an ingredient in your food preparation process has to be safe and made from an ice-machine working in sound condition.
I have heard of complaints because of parts from equipment like plastic or bolts etc. going into food from rusty equipments and this has caused choking in some cases. Metal shavings and sediments have resulted due to rust formation in water / ice.
The chemical hazards can be with heavy metals lead, cadmium etc depending on the metal used for making the pipelines and fittings.
The minerals in the water get concentrated as it becomes ice and leads to scale build up can result due and this can result in high energy and maintenance cost.
The rust can affect the taste, off colours and odour and other quality issues. If the water pipelines are rusty, water will be more turbid and this will interfere with the purification and disinfection, resulting in high TDS and this will make the ice cubes cloudy, softer & will melt faster.
Iron bacteria can be found in rust or particles of iron which leads to pipe corrosions. Though ice is not a PHF, it can carry organisms which can cause illness as the organism is live. Algal growth is possible in un-cleaned and rusty equipments.
In short, if the ice is contaminated this will result in the contamination of all the foods products being processed using the contaminated source.
So as the others have said, it’s essential to consider the rust in your ice-machine and ensure the necessary steps are taken to prevent the contamination.
Best regards,

The chlorine used for sanitizing the water used for making ice can lead to corrosion if the pH decreases.
