Explanation

To solve the question, we need to analyze each of the given statements and identify the incorrect one. Here’s a step-by-step breakdown:

### Step 1: Analyze the First Statement
- **Statement**: The dough used for making dosa and idli is fermented by bacteria.
- **Analysis**: This statement is correct. The fermentation of the dough for dosa and idli involves the action of beneficial bacteria, which help in the leavening process.

### Step 2: Analyze the Second Statement
- **Statement**: Microbes are used to ferment fish, soybean, and bamboo shoot to make food.
- **Analysis**: This statement is also correct. Various microorganisms are indeed used in the fermentation of fish, soybean, and bamboo shoots to produce different food items.

### Step 3: Analyze the Third Statement
- **Statement**: The large holes in Swiss cheese are due to the production of a large amount of CO2 by the fungi called Propionibacterium sharmani.
- **Analysis**: This statement is incorrect. While it is true that Propionibacterium sharmani is responsible for the formation of holes in Swiss cheese due to CO2 production, it is a bacterium, not a fungus. This is the key error in the statement.

### Step 4: Analyze the Fourth Statement
- **Statement**: Toddy is a traditional drink of southern India made by fermentation of microbes.
- **Analysis**: This statement is correct. Toddy is indeed a traditional fermented drink in southern India, produced with the help of various microorganisms.

### Conclusion
After analyzing all the statements, we find that the third statement is incorrect because it mistakenly classifies Propionibacterium sharmani as a fungus instead of a bacterium.

### Final Answer
The incorrect statement is: **The large holes in Swiss cheese are due to the production of large amounts of CO2 by the fungi called Propionibacterium sharmani.**
