Urinary mutagens in humans after fried pork and bacon meals
Cancer Letters
|April 1, 1984
Abstract:
Urinary mutagenic activity on Salmonella typhimurium strain TA1538 with S9 was determined after morning meals of fried pork and bacon. Both in fasting and non-fasting subjects a very marginal elevation of urinary mutagenic activity was observed, accounting for a small fraction only of the total amount of mutagens ingested.
Insights
Consuming fried pork and bacon caused a slight increase in urinary mutagenic activity. This observed mutagenic activity represented only a small portion of the total ingested mutagens.
Area of Science:
- Toxicology
- Food Science
- Analytical Chemistry
Background:
- Dietary intake of cooked meats can introduce mutagens into the body.
- Assessing the metabolic fate and excretion of foodborne mutagens is crucial for understanding health risks.
Purpose of the Study:
- To quantify urinary mutagenic activity following the consumption of fried pork and bacon.
- To compare mutagenic activity in fasting versus non-fasting individuals.
Main Methods:
- Urine samples were collected from human subjects after consuming specific fried meat meals.
- Mutagenic activity in urine was assessed using the Salmonella typhimurium strain TA1538 assay with metabolic activation (S9).
Main Results:
- A marginal elevation in urinary mutagenic activity was detected post-meal.
- The observed increase in mutagenic activity was minimal and accounted for a small fraction of ingested mutagens.
Conclusions:
- Fried pork and bacon consumption leads to a minor, detectable increase in urinary mutagenic activity.
- The human body appears to metabolize or excrete a significant portion of ingested mutagens from these food sources, as indicated by the low urinary levels.
