Claims
- 1. A hygiene monitoring method, which comprises:
a) swabbing a surface with a swab; b) collecting a sample taken up in the swab from the surface; and c) determining the presence of a carbohydrate as a measure of food residues and/or microorganisms in the sample.
- 2. The method according to claim 1, wherein the carbohydrate is lactose or sucrose.
- 3. The method according to claim 1, wherein the carbohydrate is glucose.
- 4. The method according to claim 1, which comprises adding to the sample reagents that convert the carbohydrate to give a signal.
- 5. The method according to claim 4, wherein the reagents also convert ATP to give the signal and the signal is generated more quickly in the presence of the carbohydrate than in the presence of ATP.
- 6. The method according to claim 3, which further comprises the addition of reagents that convert ATP and carbohydrates to give a signal and wherein the signal is generated more quickly in the presence of the carbohydrate than in the presence of ATP.
- 7. The method according to claim 2, which further comprises the addition of reagents that convert ATP and carbohydrates to give a signal and wherein the signal is generated more quickly in the presence of the carbohydrate than in the presence of ATP.
- 8. The method according to claim 1, which further comprises the addition of reagents that convert ATP and carbohydrates to give a signal and wherein the signal is generated more quickly in the presence of the carbohydrate than in the presence of ATP.
- 9. The method according to claim 3, which comprises adding to the sample reagents that convert the carbohydrate to give a signal.
- 10. The method according to claim 2, which comprises adding to the sample reagents that convert the carbohydrate to give a signal.
- 11. The method according to claim 9, wherein the reagents also convert ATP to give the signal and the signal is generated more quickly in the presence of the carbohydrate than in the presence of ATP.
- 12. The method according to claim 10, wherein the reagents also convert ATP to give the signal and the signal is generated more quickly in the presence of the carbohydrate than in the presence of ATP.
- 13. The method according to claim 2, wherein the carbohydrate is lactose.
- 14. The method according to claim 2, wherein the carbohydrate is sucrose.
- 15. The method according to claim 4, wherein the carbohydrate is glucose.
- 16. The method according to claim 7, wherein the carbohydrate is lactose.
- 17. The method according to claim 7, wherein the carbohydrate is sucrose.
